前言 TA5是一种低合金化的α-型钛合金,具有密集六方晶体结构,屈服强度大于588MPa,塑性、韧性、可焊性、成型性与耐海水腐蚀性优良,是一种良好的船舶结构材料。本所与有关冶金厂经十多年的合作攻关,于1982年完成了“TA5钛合金宽厚板及大型锻件”的研制,全部性能达到了原规定的技术指标,1985年10月通过了部级鉴定,并通过了铸锭、板坯、板材、锻件四个技术条件,现可批量生产。
Introduction TA5 is a low-alloyed α-type titanium alloy with a dense hexagonal crystal structure with a yield strength of more than 588 MPa. It is a good marine structure with plasticity, toughness, weldability, formability and seawater resistance material. The Institute and the relevant metallurgical plant after more than 10 years of cooperative research, completed in 1982, “TA5 titanium alloy plate and large forgings,” the development of all the performance reached the original provisions of the technical indicators, in October 1985 passed the ministerial level Identification, and adopted the ingot, slab, sheet, forging four technical conditions, is now mass production.
