摘要

以MFT（Minimum Filling Time）法自主开发了涉及高真空压铸的相关关键技术

包括真空截止阀、真空系统、模具的密封结构、涂料、浇注系统等。并以ZL101合金为对象

研究了高真空压铸下试样的力学性能和组织。结果表明

ZL101高真空压铸试样的力学性能比普通压铸有较大的提升

尤其是韧度显著增高

抗拉强度、伸长率分别比普通压铸提高约17.16、71.98;但T6热处理后

抗拉强度比铸态下提高了7.68

伸长率却下降了6.78。

Abstract

We have developed some key unites related to high vacuum die casting process based on MFT（minimum filling time） method

including shut-off valve

vacuum system

sealing structure of die

releasing agent and gating system.The mechanical properties and microstructure of ZL101 alloy in high vacuum die casting process were researched.The results indicate that

compared with those of one in conventional die casting

tensile strength and elongation of the ZL101 alloy in high vacuum die casting reach up to 204.55 MPa and to 8.41%

increased by 17.16% and by 71.98%

respectively

showing the great improvement of mechanical properties

especially ductility.However

compared with as-cast one

T6 treated ZL101 alloy after high vacuum die casting are increased by 7.68% in tensile strength and decreased by 6.78% in elongation.
