常常用 TC_4钛合金制成航空发动机的压气机叶片。发动机制造部门对叶片的生产工艺进行改革:采用高速锤模锻,再进行冷轧;使尺寸精确,以减少切削加工量。因此,要求材料有较好的塑性,拟定改用 TC_3 TC_4 titanium alloy is often used to make aeroengine compressor blades. Engine manufacturing sector of the blade production process to reform: the use of high-speed hammer forging, and then cold-rolled; the size of precision, in order to reduce the amount of cutting. Therefore, the material is required to have better plasticity, the proposed change to TC_3
