Description
Technical field
The present invention relates to a kind of high temperature preheating powder that utilizes self propagating high temperature synthetic technology (SHS) to be produced, utilize water, be applicable to the technology of the difficult fixed metal of preparation high density (or pottery) composite and FGM (FGM) thereof for transmission medium carries out the method for bidirectional blasting and concreting to difficulty fixed (as W, Mo, Ti and pottery etc.) dusty material.
Background technology
Because refractory metal such as W, Mo, Ti and ceramic material are subjected to the restriction of material character itself, normal temperature explosive consolidation technology does not often reach the required surface temperature rise of powder particle bonding, therefore is difficult to satisfy the needs of difficult fixed metal of preparation high-quality or ceramic composite.Pre-heating powder explosive consolidation technology thereby become the dominant direction of Recent study, heating techniques such as electrical heating, self propagating high temperature synthetic (SHS) reaction intensification are also therefore developed.
Gorobtsov and Roman combine the shock wave effect with the green compact technology of being rapidly heated, adopt refractory materials such as the fixed tungsten heavy alloy of high temperature explosive consolidation (HEC) technology.Powder is opened heating furnace cover in electric furnace after the preheating when main charge is installed detonator, with explosive above guide rail slides into the container that fills pre-heating powder.Mobile powder was controlled in 20 seconds to the time of detonating charge.Test shows adopts the HEC method that is higher than the material recrystallization temperature can obtain the theoretical density pressed compact.This method only is applicable to the explosive consolidation of simple metal, prealloy and ceramic material.
Disclosed quality of utilizing chemical-reacting furnace to improve self propagating high temperature synthetic (SHS) pottery with No. 5139720 United States Patent (USP)s of Takeda No. 4655830 of people such as Akashi.People's such as Akashi patent has also disclosed a kind of explosive consolidation device with a plurality of sample boxs, and this device and external heat furnace accretion lump together.After the temperature rising of heater, explosive container is slided into remote initiation on the consolidation device with whole steel explosive consolidation device.
People's such as Niiler No. 5114645 United States Patent (USP)s have disclosed the two-step method of preparation theoretical density ceramic material, and this method is promptly carried out explosive consolidation at sample when spreading synthetic first base.
No. 5996385 United States Patent (USP)s of Kecskes are in conjunction with people's such as Niiler two-step method and people's such as Takeda, Akashi chemical heat stove.The SHS synthetic material provides preheating its coated required heat of metal or alloy powder only as thermal source.This method can prepare solid density and be higher than 90% high purity tungsten and tungsten-bast alloy.For same purpose, people such as the Japan Kumamoto A.Chiba of university have developed shock wave cumulative explosive consolidation device in the pre-heating powder water, the Mohaupt effect of this technology has improved maximum impact pressure, and its shock wave continuous action time is more much longer than the film flying loading explosive consolidation technology of Sawaoka and Akashi exploitation.Powder heats under the condition of protective atmosphere, and the powder preheating descends heating furnace by two cylinders that link to each other with oil-gas converter after finishing, and explosive train component is placed on the powder assembly thereupon, and explosive detonated in the moment of its underpart contact pre-heating powder assembly.
People such as M.A.Meyers use the uniform principle of cylinder charger dose and have designed plane wave explosive consolidation device.The rectangle sample box left-right symmetry of this device is also put, and places metal caul therebetween and can fall into as absorbing catching of back wave.Two groups of film flying symmetric arrangement are transferred to sample box with the energy of explosive., propagate under the sliding detonation wave direction at device top detonating charge with linear plane wave producer (arranging the triangle powder column of emptying aperture), on the metal caul of centre, clash, avoided the destruction of sample box.When the blast pressure that requires was low, this device can be without film flying, and this moment, explosive directly contacted with sample box.This device also is applicable to the preheating explosive consolidation of difficult consolidated powder, to improve the ductility of matrix powder.Sample box slips into along the guide plate on destructor top in electric furnace after the preheating.
Yoshida explosive consolidation device also adopts planar impact ripple head-on collision layout, has improved the peak value surge effectively.Sample box is positioned on the left and right sides shock wave head-on collision point, and its surge is the twice of unidirectional shock wave pressure, and pressure thereby can reach the megabar magnitude in the sample can be fixed with diamond dust.
Adopt from the advantage that spreads the system pre-heating powder and be that its heat time heating time short (in second), energy consumption little, heating-up temperature is far above traditional Electric heating.Simultaneously do not need the remote control of mobile high temperature powder body, but directly thermal source is enclosed in around the sample, powder preheating and explosive consolidation carry out in same set of device.Its shortcoming need to be corresponding insulating unit, and destructor is installed and shown complicated slightly.Electrically heated shortcoming is heat time heating time long (in hour), easily causes mould to soften, cause tungsten etc. to incorporate base material and forms too much solid solution.Plane wave head-on collision placement peak pressure height, but the pulse duration is shorter, and the stretching ripple that shock wave head-on collision back produces is unfavorable for the raising of sample explosive consolidation quality.
