新日本钢铁有限公司在东邦钛有限公司的配合下,研制出强度与延展性平衡的优质合金高强度钛“TIX系列”。通常,纯钛具有良好的耐蚀性,但作为强度材料使用却受到限制。而钛合金由于加入了铝、钒、钼、锆等成分,有价格高及难加工等种种制约。而今,该公司研制成功的“TIX系列”合金,使用价格便宜的氧、氮、铁等作为添加元素。如经过适当的处理,则具有以往的材料所没有的特性,是既有纯钛特性,又有钛合金特性的全新材料。该系列各项主要特性如下: 1、耐蚀性不亚于纯钛; 2、抗拉强度高达784.8～882.9MPa,介于以往纯钛与钛合金之间; 3、屈服比大于0.85(屈服比=屈服强度/抗拉强度);
Nippon Steel & Steel Co., Ltd. cooperated with Toho Co., Ltd. to develop a high-quality titanium alloy “TIX Series” of high strength and ductility. In general, pure titanium has good corrosion resistance, but its use as a strength material is limited. The titanium alloy due to join the aluminum, vanadium, molybdenum, zirconium and other ingredients, there are high prices and difficult processing constraints. Today, the company developed a successful “TIX series” alloy, using inexpensive oxygen, nitrogen, iron and other elements as an addition. Such as the proper treatment, it has the characteristics of the material has not, is both the characteristics of pure titanium, but also a new titanium alloy material properties. The main features of the series are as follows: 1, the corrosion resistance of no less than pure titanium; 2, the tensile strength of up to 784.8 ~ 882.9MPa, between past pure titanium and titanium alloy; 3, yield ratio greater than 0.85 = Yield strength / tensile strength);
