一、前言 众所周知,钛合金具有比重小、比强度高,耐腐蚀性优良等特性,是一种非常宝贵和有着广泛应用前途的新型金属材料,因此被称为发展中的“第三金属”。随着各部门对钛合金制件需要量的日益增长,钛材的加工工业获得了较快的发展,与此同时,也产生了大量的残钛料。除了在海绵钛生产中约产 I. Preface As we all know, titanium alloy with a small proportion, high strength, excellent corrosion resistance and other characteristics, is a very valuable and has a wide range of promising new metal materials, it is called the development of “the third metal.” With the increasing demand of various departments of titanium alloy parts, titanium processing industry has achieved rapid development, at the same time, also produced a large amount of residual titanium material. In addition to about production in the production of titanium sponge
