摘要

采用自制的倾斜板冷却剪切装置制备ZL104半固态浆料

研究了倾斜板倾角对半固态ZL104合金组织细化及圆整程度的影响。结果表明

倾斜板倾角对ZL104合金组织内部剪切作用及物理冶金作用具有显著的影响。倾斜板倾角在30°～45°区间内能够得到晶粒球化、细化效果较好的合金组织。45°倾角得到的ZL104组织绝大部分晶粒等效直径小于43μm

40%以上的晶粒形状因子在0.75以上

具有较好的晶粒细小度及圆整度。

Abstract

An experimental equipment with inclined plate cooling and shearing has been developed to prepare semi-solid ZL104 alloy slurry.The effects of inclined plate angle on microstructure refinement and spheroidization in semi-solid ZL104 alloy were investigated.The results show that the inclined plate angle has remarkable effect on physical metallurgy and shear action of ZL104 alloy.Fine spherical grain in the semi-solid ZL104 alloy slurry can be obtained in range of 30 °

45 °

and the major grain equivalent diameters are less than 43 μm and more than 40% of the grain shape factor is in 0.75 above at 45 °

exhibiting better grain fine degree and roundness.
