在热力耦合与刚塑性有限元分析的基础上,利用Deform模拟了Ti40阻燃钛合金包套的挤压变形过程,分析了温度场和应变场。结果表明:采用包套挤压可使Ti40合金保持在较高温度的挤压;提高挤压温度还可提高挤压坯料的温度,降低坯料流变应力,增加坯料变形程度并降低包套冷硬层厚度。
Based on the thermal coupling and the rigid plastic finite element analysis, Deform simulates the extrusion deformation process of Ti40 flame-retardant titanium alloy sleeve, and analyzes the temperature field and strain field. The results show that Ti40 alloy can be kept at a higher temperature by extrusion coating. Increasing the extrusion temperature can also increase the extrusion billet temperature, reduce the flow stress, increase the deformation of the billet and reduce the chill Layer thickness.
