Zr60Ti40合金铸造成形数值模拟及验证
Numerical Simulation and Verification on Zr60Ti40 Alloy Casting
摘要
Abstract
Taking titanium-zirconium alloy with nominal composition of Zr60Ti40 as the research object and simple cylinder structure castings as the carrier,numerical simulation and experimental verification of schemes of different casting processes and different mold materials were carried out.The simulation results show that metal liquid filling is smooth for the centrifugal pouring using ceramic shell and the gravity top pouring using single gate ceramic shell,and no sputtering and confluence phenomenon appear.Liquid metal feeding effect is good,and no large scale shrinkages generate in the castings.According to the experimental verification,there are no surface defects such as cold shut on the appearance in the castings,and no obvious defects such as large-scale shrinkage,blowhole and inclusion are found inside the castings,which is in good agreement with the numerical simulation results.关键词
