根据我厂的生产实际,对TA_7板材组织进行了观察,着重观察热轧和冷轧板在不同加热温度、退火温度和变形量等工艺条件下的组织变化。现就我们所做的工作小结如下。一、简介TA_7(T_i—5Al—2.5S_f)钛合金是一种α型钛合金。在室温下得到完全的α相组织,甚至从高于β相线温度迅速冷却时,α相仍处于平衡状态。其加工工艺和热处理方 According to the actual production in our factory, the TA_7 plate was observed and the microstructures of the hot-rolled and cold-rolled plates were observed under different processing conditions, such as heating temperature, annealing temperature and deformation. The work that we did now is summarized as follows. I. Introduction TA_7 (T_i-5Al-2.5S_f) titanium alloy is an α-type titanium alloy. The complete α-phase structure is obtained at room temperature, and the α phase is still in equilibrium even when rapidly cooled from the β-phase line temperature. Its processing technology and heat treatment side
