The preparation method of the high-strength deformation platina of the described Mg of containing is: adopt protective covering method to carry out melting, copper, magnesium, titanium add with Zn-Cu, Cu-Mg, Zn-Ti master alloy form respectively, zinc, aluminium then add with pure zinc, fine aluminium form respectively, smelting temperature is 620～710 ℃, after treating that the alloy liquation mixes, under 450～500 ℃, be cast into ingot casting; Ingot casting is after 360～380 ℃ of homogenizing are handled 6～10h, and at 240～310 ℃ of following extrusion moldings, extrusion ratio is 10～20; The extruding back is at 170～210 ℃ of annealing 2～4h.
The preparation method of above-mentioned Zn-Ti master alloy is: the pure Ti that will account for Zn-Ti master alloy total mass 5～8% adds melting in the Zn liquation, treat that Ti all melts and mixes after, be incubated 25～35 minutes, be cast into ingot casting then.
The preparation method of the high-strength deformation platina of a kind of Mg of containing of the present invention: described melting is to carry out in medium-frequency induction furnace.
The high-strength deformation platina of a kind of Mg of containing of the present invention is to reach the effect of reinforcement by adding alloying elements such as an amount of copper, magnesium, aluminium, titanium, and the action effect that adds element is as follows:
The effect of Cu mainly shows solution strengthening, and the Cu solid solution of trace causes lattice distortion in Zn, to the slippage generation obstruction of dislocation, thus reinforced alloys.The solid solubility of Cu in zinc is little under the normal temperature, and Cu can form intermetallic compound ε phase (CuZn
4), this hard second Mass of meeting is distributed in matrix, and is obvious to the strengthening effect of alloy.But when the copper too high levels, the ε phase (CuZn that the crystal boundary place generates
4) cause alloy plasticity sharply to descend too much.Therefore, through a large amount of evidences, in the time of between copper content (massfraction %) fixes on 0.1～5.0%, alloy has higher intensity, and over-all properties is also better.
Mg can solid solution in matrix, but its solid solubility is little, the solid solubility of magnesium only is 0.005% under the room temperature.Solid solution strengthening effect is played in the adding of magnesium, improves alloy strength and creep-resistant property; When Mg content increased, Mg can generate intermetallic compound Cu with Cu
2Mg, disperse is distributed in matrix, can largely improve the intensity of alloy; And magnesium can also prevent intergranular corrosion; But along with Mg content increases, make the flowability of alloy liquid reduce, be unfavorable for the castability of alloy.Therefore the present invention fixes on Mg content (massfraction %) between 0.05～3.0%.
Al can crystal grain thinning, also plays solution strengthening, and tensile strength of alloys and creep strength are obviously improved, and the corrosion resistance nature that improves alloy is also had certain effect.Alloy is in fusion process, and Al can improve the flowability of zinc liquid largely, thereby improves its castability, aluminium can also form one deck compact oxide at molten surface, and the energy slag making, can prevent the alloy liquid oxidation, the castability that improves alloy there is very big benefit.The add-on of Al in the alloy of the present invention (massfraction %) is: 0.1～2.5%.
Ti can generate intermetallic compound TiZn with the zinc reaction
15, be distributed in the crystal boundary place, the intensity that improves alloy there is good supplementary function; In addition, Ti adds as a kind of alterant, mainly is the basic phase of refinement, and improves frangible compounds that impurity and be mingled with the form and the distribution of grade in an imperial examination two-phase improves the over-all properties of alloy.The addition of Ti of the present invention (massfraction %) is: 0.02～0.3%.
In sum, reasonable component formula of the present invention, prepared zinc alloy is the zinc alloy with higher intensity and good over-all properties, and alloy liquid good flowing properties, have advantages of good casting, can be used as structured material and use, be specially adapted to the manufacturing structure part, as fields such as bathroom hot-water heating, five metals and automobile industry's component, be a kind of material that has very much application prospect.
