目前,在钛结构锻件的生产中,特别着重机械热处理技术的研究,因为要发展一种兼有高淬透性高韧性和适用强度的新合金往往需要较长的时间和较多的资金,而对现有的常用钛合金的生产工艺进行全面的详尽的研究,以求在改善全面的综合性能的基础上提高其韧性则具有更加现实的意义,本文对常用的不同氧含量(0.13—0.20%)Ti—6—Al—4V和Ti—6Al—6V—2Sn合金作8种成分/工艺变量的研究(见表1),结果表明,机械热处理对显微组织的调查而导致的全面性能的改善是明显的,特别是把韧性提高了50—70%之多。
At present, special attention has been paid to the research of mechanical heat treatment technology in the production of titanium forgings, since it takes a long time and a lot of money to develop a new alloy with high hardenability, high toughness and suitable strength Comprehensive and exhaustive research on the existing commonly used titanium alloy production technology in order to improve the overall comprehensive performance based on the increase of its toughness is more realistic meaning, this article commonly used different oxygen content (0.13-0.20% ) Ti-6-Al-4V and Ti-6Al-6V-2Sn alloy for 8 components / process variables (Table 1), the results show that mechanical heat treatment on the microstructure of the survey results in the overall performance improvement Is obvious, especially the toughness increased by 50-70%.
