摘　　要：通过测试拉伸性能(σ_b,σ_(0.2),δ_5,n,r)的方法,研究了换热器用纯钛TAl薄板的冷成形性,同时进行了杯突、拉深、扩孔试验,结果表明,n值与杯突值有很好的正相关性。σ_(0.2),n,r值各向异性较大。文章还讨论了氧含量对力学性能的影响。Cold formability of titanium(TAl) sheet used for heat exchanger has been studicd. Tensile properties(σ_b,σ_(0.2),δ_5,n,r) have been tested, and erichsen, deep drawability and expanding tests have been done at the same time. It is proved that the n-Value has a direct relationship to IE-Value. The influence of oxygen contents to mechanical properties has been discussed.
