采用控制结晶法制备了初生α相颗粒圆整、尺寸细小、分布均匀 ,适合半固态加工的ZL10 1合金。初生α相的平均等效直径为 90 μm ,平均形状系数为 0 .75。在自行研制的压缩试验装置上 ,以不同变形温度 (恒定变形速率 0 .0 1s-1) ,分别对常规铸造组织和颗粒状组织浆料进行半固态直接压缩变形 ,从表观质量、极限塑性和变形量等 3个方面来评价浆料的变形特性。 5 85℃时颗粒状半固态组织浆料的极限塑性可达 33.10 % ,而普通树枝晶组织浆料的极限塑性只有 2 7.44 % ;5 65℃时颗粒状半固态组织的极限塑性为 2 2 .36% ,而普通树枝晶组织浆料的极限塑性只有 2 1.36%。半固态颗粒状组织的压缩变形主要以液相流动为主 The controlled crystallization method was used to prepare the primary α phase particles round, small size, uniform distribution, suitable for semi-solid processing ZL10 1 alloy. The average equivalent diameter of the primary α phase was 90 μm and the average shape factor was 0.75. In the self-developed compression test device, the semi-solid direct compression deformation of conventional foundry and granular slurry was carried out at different deformation temperatures (constant deformation rate 0. 01s-1), respectively. The apparent mass, ultimate ductility And deformation of the three aspects to evaluate the deformation properties of the slurry. The ultimate ductility of granular semi-solid slurry at 5 85 ℃ is up to 33.10%, while that of normal dendrite is only 2 7.44%. The ultimate ductility of granular semi-solid at 52 ℃ is 22. 36%, while the ordinary dendrite microstructure of the plastic limit of only 21.46%. The compressive deformation of the semi-solid granular structure is mainly dominated by the liquid phase flow
