一、概述73年,上海地区,在解剖 Tc_4钛合金叶片中,发现低倍组织上有亮条,引起了各单位的重视。随后,有的单位也先后在 Tc_4钛合金的成品、半成品、坯料、甚至铸锭中发现了类似的情况。这样,Tc_4钛合金的亮条成为众所周知的问题,急待解决。第二届钛和钛合金学术会议上,对Tc_4钛合金中存在的亮条问题进行了交流和讨论。《稀有金属合金加工》编辑部也专栏刊登了这个问题的讨论文章。由于各生产厂家、用户的生产条件和工艺控制存在差异。在铸锭、坯料、热加工半成品和成品中,出
First, an overview 73 years, Shanghai, anatomical Tc_4 titanium alloy blades, found that low magnification of the organization have bright, aroused the attention of all units. Subsequently, some units also successively in Tc_4 titanium alloy finished, semi-finished products, billets, and even cast ingot found a similar situation. In this way, Tc_4 titanium alloy bright become well-known issues, urgent solution. At the second session of the Titanium and Titanium Conference, the bright spots in Tc_4 titanium alloy were discussed and discussed. The editorial board of “Rare Metal Alloy Machining” also published a discussion article on this issue. Due to the various manufacturers, the user’s production conditions and process control differences. In ingots, blanks, thermal processing of semi-finished products and finished products, out
