摘要

液态铸锻双控成形

是综合了压力铸造和锻造工艺特性而提出的一种新的成形方法。通过铸锻双控成形与普通压铸在相同工艺参数条件下

采用正交试验的方法进行AZ91D镁合金样件的试制

并对双控成形制件进行T6热处理

然后对样件进行力学性能测试及微观组织观察

得出在相同工艺参数条件下

与普通压铸相比双控成形制件的抗拉强度和伸长率分别提高84.394%和101.761%;经热处理后分别提高94.672%和121.617%

且微观组织晶粒细小。

Abstract

The liquid combination process of die casting and forging is a new forming method which combines processing property of die casting with that of forging.Under the condition of the same process parameter and with the help of orthogonal test

AZ91D magnesium test samples were preproduced by the combination process of die casting and forging and the common die casting

respectively T6 method was also employed to treat the test samples.In addition

the mechanical property of samples was tested

and the microstructure of samples was observed.It was indicated that

under the condition of the same process parameter

the tesile strength and extensibility of the test samples produced by the liquid combination process of die and forging

were increased by 84.394% and 101.761% respectively

the tesile strength and extensibility of the test samples treated by T6 were increased by 94.672% and 121.617% respectively;and the size of grain of the test samples is much smaller

in comparison with those of test samples produced by common die casting.
