Description
Oppfinnelsen vedrører en fremgangsmåte til fremstilling av metallpulver av folier og folieformede granulater på aluminium-basis hvis legeringsbestanddeler ved hjelp av høy størknings-hastighet i størrelsesorden fra 10 5 til 10 6°C pr. sekund over-føres i overmettede oppløsninger. The invention relates to a method for the production of metal powder from foils and foil-shaped granules on an aluminum basis whose alloy constituents by means of a high solidification rate in the order of magnitude from 10 5 to 10 6 °C per second is transferred into supersaturated solutions.
Ifølge DE-OS 27 43 090 er det kjent i en innretning for opp-deling og hurtig stivning av metalliske smelter med en sentral-roterende tallerken å fremstille folieformede granulater på basis av aluminium. Granulatene skal ved den høye stivningshastighet på mer enn 10^°C pr. sekund få en optimal struktur-oppbygning og være spesielt egnet for videreforarbeiding ved forpressing og strengpressing, eventuelt trådtrekking. Med den kjente innretningen skal det oppnås at ved aluminiums-legeringer med noen vekt-% jern vokser mengden av fint hurtigstivnede granulatpartikler, og mengden av grovere leger-ingspartikler som er stivnet med ikke tilstrekkelig hastighet, nedsettes. De med de kjente granulater fremstilte halvfabrikata skal ha gode mekaniske egenskaper og korrosjonsfastighet samt kunne anvendes inntil en temperatur på 300°C. According to DE-OS 27 43 090, it is known in a device for dividing and rapidly solidifying metallic melts with a central rotating plate to produce foil-shaped granules based on aluminium. At the high solidification rate of more than 10^°C per second get an optimal structural build-up and be particularly suitable for further processing by pre-pressing and strand pressing, possibly wire drawing. With the known device, it is to be achieved that in the case of aluminum alloys with some weight % iron, the amount of fine, rapidly solidified granule particles increases, and the amount of coarser alloy particles that are solidified at an insufficient speed is reduced. The semi-finished products made with the known granules must have good mechanical properties and corrosion resistance and can be used up to a temperature of 300°C.
For å virkeliggjøre en høy avkjølingshastighet fra IO<5>til 10^°C pr. sekund må metallsmeltens varme umiddelbart over-føres til et metallisk fast legeme. Derved bør smelte-sjiktets tykkelse bare være liten for at det kan oppnås den nødvendige ekstremt høye avkjølingshastighet i det samlede tverrsnitt. Dette er blitt forsøkt på forskjellige måter. Således ble flytende metalldråper av en legering av aluminium med 8% Fe sammenpresset mellom to kjølte kopper-plater. Man har også forsøkt å helle metallet mellom to koppervalser med meget snever spalte. I alle tilfeller får man imidlertid bare metallfolie hvis tykkelse ligger omtrent mellom 10 og 100 um. Ved større tykkelser lar det seg på grunn av for langsom avkjølingshastighet ikke gjøre å oppnå den ønskede struktur. To realize a high cooling rate from 10<5> to 10^°C per second, the heat of the metal melt must be immediately transferred to a metallic solid body. Thereby, the thickness of the molten layer should only be small so that the necessary extremely high cooling rate can be achieved in the overall cross-section. This has been attempted in various ways. Thus, liquid metal drops of an alloy of aluminum with 8% Fe were compressed between two cooled copper plates. Attempts have also been made to pour the metal between two copper rollers with very narrow slits. In all cases, however, you only get metal foil whose thickness is approximately between 10 and 100 µm. With larger thicknesses, it is not possible to achieve the desired structure due to too slow a cooling rate.
For å nytte de gunstige egenskaper av tynne metallfolier, To take advantage of the favorable properties of thin metal foils,
har man forsøkt herav ved valsing, strengpressing eller smiing å fremstille kompakte halvfabrikata. Disse er imidlertid i deres samlede tverrsnitt ikke tilstrekkelig tette og kompakte . attempts have been made to produce compact semi-finished products from this by rolling, strand pressing or forging. However, these are not sufficiently dense and compact in their overall cross-section.
Oppfinnelsen vedrører en fremgangsmåte til fremstilling av metallpulvere av folier og folieformede granulater av en aluminiumlegering, hvis legeringbestanddeler ved høy stivningshastighet i størrelsesorden fra 10 til 10 °C/sek. overføres i en fast overmettet oppløsning, idet fremgangsmåten erkarakterisert vedat folier resp. folieformede granulater av en AlCuMg- eller AlZnMgCu-legering med 5 til 8% Fe, Co eller Ni knuses til en partikkelstørrelse mellom 10 og 50 |am, idet forholdet mellom lengde og bredde og tykkelse av enkeltpartiklene ikke overskrider faktoren 10. The invention relates to a method for producing metal powders from foils and foil-shaped granules of an aluminum alloy, whose alloy constituents at a high solidification rate in the order of 10 to 10 °C/sec. is transferred in a solid supersaturated solution, as the method is characterized by foils or foil-shaped granules of an AlCuMg or AlZnMgCu alloy with 5 to 8% Fe, Co or Ni are crushed to a particle size between 10 and 50 |am, the ratio between length and width and thickness of the individual particles not exceeding a factor of 10.
Ifølge oppfinnelsen er dette mulig når disse folier eller foliestykker før kompaktering og forming males i en egnet slag- eller skjæremølle til fint pulver hvis partikkel-størrelse ikke utgjør mer enn 10 ganger tykkelsen av folie-materialet. Et på denne måte frembragt metallpulver lar seg under oppvarming eventuelt i vakuum eller beskyttelses-gass forarbeide til kompakte partikler som enten umiddelbart finner anvendelse som formdeler eller deretter videre-formes ved valsing, smiing eller strengpressing og således kan bringes i alle ønskede halvfabrikataformer. På denne måten lar det seg fremstille anvendelsesklare halvfabrikata av enhver ønsket sammensetning. Derved er det mulig å kombinere egenskapene ifølge splat-cooling-metoden frembragte aluminiumlegeringer med Fe, Ni, Co, Ti, Zr, Cr, W, Mo, V According to the invention, this is possible when these foils or foil pieces, before compacting and shaping, are ground in a suitable impact or cutting mill to a fine powder whose particle size does not amount to more than 10 times the thickness of the foil material. A metal powder produced in this way can, under heating, optionally in a vacuum or protective gas, be processed into compact particles which either immediately find use as mold parts or are then further shaped by rolling, forging or strand pressing and can thus be brought into any desired semi-finished form. In this way, it is possible to produce ready-to-use semi-finished products of any desired composition. Thereby, it is possible to combine the properties of aluminum alloys produced according to the splat-cooling method with Fe, Ni, Co, Ti, Zr, Cr, W, Mo, V
og lignende med de konvensjonelle legeringers. Således har eksempelvis en AlCuMg- eller AlZnMgCu-legering som for-uten de vanlige innhold av Cu, Mg, Zn dessuten også til-settes 6-8 vekt-% Fe, Co eller Ni, en fasthet som ligger langt over de kjente verdier. Samtidig forbedres tallrike andre egenskaper, spesielt også varmfasthet, permanent and the like with the conventional alloys. Thus, for example, an AlCuMg or AlZnMgCu alloy to which, in addition to the usual contents of Cu, Mg, Zn, 6-8% by weight Fe, Co or Ni is also added, has a strength that is far above the known values. At the same time, numerous other properties, especially heat resistance, are permanently improved
svingforhold og korrosjonsbestandighet. turning conditions and corrosion resistance.
På den nevnte måte er det mulig å fremstille helt nye leger-inger med hittil enda ikke oppnåelige egenskaper. In the aforementioned manner, it is possible to produce completely new alloys with hitherto unattainable properties.
Metallpulveret består fortrinnsvis av enkeltpartikler hvor forholdet mellom lengde respektivt bredde:tykkelse av enkeltpartiklene ikke overskrider faktoren 10. Dette betyr at hver partikkel med en bestemt utgangstykkelse males så sterkt at den største utvidelse (målt i den opprinnelige folieplan) ikke overstiger 10 ganger folietykkelsen. Det oppnås altså plateformede partikler. The metal powder preferably consists of individual particles where the ratio between length and width:thickness of the individual particles does not exceed a factor of 10. This means that each particle with a specific initial thickness is ground so strongly that the largest expansion (measured in the original foil plane) does not exceed 10 times the foil thickness. Plate-shaped particles are thus obtained.
Ved andre partikkeldimensjoner respektivt former oppnås ingen kompakte halvfabrikata som er tilstrekkelig tette. Dette er å føre tilbake på at det ikke finner sted noen sammensveising på alle sider av partiklene. With other particle dimensions or shapes, no compact semi-finished products are obtained that are sufficiently dense. This is due to the fact that no coalescence takes place on all sides of the particles.
