前言钛是一种新型的金属材料。钛工业的发展相当快,钛及其合金已经成为对现代化工业的发展起着重要作用的金属材料。钛及其合金比重轻(为钢的60%),强度高,(高强钛合金抗张强度能达到180公斤/毫米~2)比强度大,耐腐蚀,耐低温,在500℃以下能保持良好的机械性能(工业纯钛使用温度一般在330℃以下),所以世界各国对钛工业的发展及钛材推广应用工作都很重视。 Preface Titanium is a new type of metal material. Titanium industry has developed quite rapidly, titanium and its alloys have become the metal material that plays an important role in the development of modern industry. Titanium and its alloy light weight (60% of steel), high strength, (high strength titanium alloy tensile strength can reach 180 kg / mm ~ 2) than the strength, corrosion resistance, low temperature, below 500 ℃ to maintain good Of the mechanical properties (industrial pure titanium temperature is generally below 330 ℃), so the world in all countries on the development of titanium industry and titanium to promote the application of work are very important.
