摘要

采用倾斜管过流冷却-转移法生产半固态流变压铸件

研究了压铸工艺对ZL101铝合金半固态流变压铸件性能的影响

以及半固态压铸件经T6热处理之后性能的改变。对比研究了液态与半固态压铸件的力学性能。结果表明

在浇注温度为595℃、压射速度为1.8m/s时

压铸件性能最佳

此时较浇注温度为630℃的液态压铸件的抗拉强度提高了11%。经热处理的半固态压铸件抗拉强度与伸长率都得到改善。液态与半固态压铸件试样的拉伸断口为准解理断裂

经热处理的半固态压铸件试样的拉伸断口为韧性断裂。

Abstract

Die casting semi-solid ZL101 alloy prepared by inclined slope cooling-transferring method was conducted. Effects of processing parameters on properties of semi-solid rheoforming ZL101 alloy die castings were investigated

and the change of properties of the semi-solid die casting ZL101 parts after T6 heat treatment was analyzed. Mechanical properties of semi-solid die casting parts were comparatively analyzed with those of conventional die casting parts. The results reveal that

the semi-solid die casting parts exhibit desirable mechanical properties with pouring at 595 ℃ and injecting at 1.8 m/s

and the elongation is increased by 11% compared with that of conventional die casting parts at 630℃. Tensile strength and elongation of the semi-solid die casting parts after heat treatment are greatly improved. The fracture mechanism of both conventional die casting parts and semi-solid die casting parts are characterized by quasi-cleavage fracture

while semi-solid die casting parts after heat treatment are characterized by ductile fracture.
