半固态注射成形工艺参数对AZ91D流动性及力学性能的影响
Effect of semi-solid injection molding process parameters on the flowability and mechanical properties of AZ91D
摘要
Abstract
Semi-solid injection molding technology for magnesium alloys has developed rapidly in various fields,and the filling ability of semi-solid slurry plays a crucial role in the mechanical properties of castings.In this study,the effects of forming temperature,injection pressure,mold temperature,and holding time on the filling distance of AZ91D semi-solid slurry were systematically investigated in order to clarify the flow behavior of the semi-solid slurry and the influence of filling distance on mechanical properties.The experimental results show that the optimal filling quality is achieved at a forming temperature of 595~600 ℃,a mold temperature of 230~250 ℃,an injection velocity of 2.0~2.3m/s,and a holding time of 1.0s.The results also indicate that both excessively short and excessively long distances from the injection gate are detrimental to the mechanical properties.关键词
