钛合金是一种新型结构及功能材料,它具有优异的综合性能,密度小,比强度高。钛合金的比强度高于铝合金和钢,韧性也与钢铁相当。钛及钛合金抗蚀性能好,优于不锈钢,特别是在海洋大气环境中抵抗氯离子的侵蚀和微氧化气氛下耐蚀性好,钛合金的工作温度较宽,低温钛合金在-253℃还能保持良好的可塑性,而耐热钛合金的工作温度可达550℃左右,其耐热性明显高于铝合金和镁合金,同时具有良好的加工性、焊接
Titanium alloy is a new type of structural and functional materials, it has excellent overall performance, low density, high strength. The specific strength of titanium alloy than aluminum and steel, toughness and steel quite. Titanium and titanium alloys have good corrosion resistance and are superior to stainless steel, especially in the atmospheric environment of the sea to resist the corrosion of chloride ion and the corrosion resistance under the micro-oxidation atmosphere. The working temperature of the titanium alloy is wide. The low temperature titanium alloy is stable at -253 ℃ But also to maintain good plasticity, and heat-resistant titanium alloy working temperature up to about 550 ℃, the heat resistance was significantly higher than aluminum and magnesium alloys, while having good workability, welding
