Effect of Annealing Temperature on Microstructure and Mechanical Property of High Purity Titanium Cold Rolled Plate

State Key Laboratory of Rolling Technology and Continuous Rolling Automation, Northeastern University, Shenyang 110819, China

摘要

摘要: 以高纯(99.995%)钛板材为研究对象,对压下量为60%的冷轧高纯钛板材进行了不同温度的退火处理。采用 EBSD技术对高纯钛板材的显微组织进行了表征,对退火后的钛板材进行拉伸试验和硬度测试。结果表明,随着退火温度的提高,高纯钛板材的抗拉强度和硬度不断下降,而伸长率得到提高;在600 ℃下退火10 min后,板材的伸长率达到(74.6±5.0)%,抗拉强度达到(217±2) MPa。显微组织结果表明,在600 ℃下退火10 min后,晶粒已完全转变为无畸变的等轴晶,KAM值降低至0.16°,表明此时板材内部几乎不存在局部应变和储存能。这主要是因为随着退火温度的提高,晶粒的位错密度降低,软化效果增强。

Abstract: The cold rolled high purity (99.995%) titanium plate with 60% reduction is annealed at different temperatures. The microstructure of the high-purity titanium plate is characterized by EBSD technology, and the tensile and hardness tests are carried out. The results show that with the increase of annealing temperature, the tensile strength and hardness of the high-purity titanium plate decrease continuously, and the elongation increases. After annealing at 600 ℃ for 10 minutes, the elongation of the plate reaches (74.6±5.0)%, and the tensile strength reaches (217±2) MPa. The microstructure shows that the grains have been completely transformed into equiaxed grains without distortion after being annealed at 600 ℃ for 10 minutes, and that the KAM value is reduced to 0.16°, indicating that there is almost no local strain and stored energy in the plate at this moment. The reason is that with the increase of annealing temperature, the dislocation density of the grain decreases, and the softening effect increases.
