摘要
Ti-15-3合金的热镦粗过程进行了数值模拟和实验研究.分析了变形程度对Ti-15-3合金组织的影响。结果表明,Ti-15-3合金件热变形后,组织很不均匀.为了保证零件的性能,得到晶粒细化的均匀组织,热变形过程中的变形程度需要足够大。
This paper introduces the simulation of hot upset process and the influence of deformation degree on the mi- crostructure of Ti-15-3 alloy. The result shows,Ti-15-3 alloy microstructure is not uniform after hot working and degree of deformation should be big enough to ensure the performance of parts and attain uniform microstructure with fine grains.
