Abstract

The invention discloses an impact resistant composite alloy material. The impact resistant composite alloy material is smelted from the following alloy elements according to mass percent: 12.8 to 13.6% of copper, 3.52 to 3.79% of chromium, 0.82 to 1.64% of nickel, 0.74 to 0.96% of germanium, 0.021 to 0.024% of cerium, 0.026 to 0.037% of yttrium and the balance of magnesium. A preparation method comprises the following steps of preheating pure metal powder which contains all of the elements according to to-be-smelted elements in an aluminum alloy material to 364 DEG C, then putting in a ceramic crucible so as to be smelted for 1 h at the smelting temperature of 850 to 940 DEG C, transferring to a medium-frequency induction heating furnace after smelting so as to be refined at the refining temperature of 1152 to 1264 DEG C, extracting slags after refining, finally, pouring into a die which is preheated to 450 to 480 DEG C, and demolding. The impact resistant composite alloy material which is prepared by reasonably setting the proportion, the production process and the put order has good comprehensive mechanical properties and especially has strong impact resistant performance, the alloy life can be obviously prolonged, the damage rate of machinery is reduced, and the safety factor is increased.
