以简单压扁、单向热轧的Ti-6Al-4V合金板坯为试验料,采用完全β处理方法,使原铸锭遗传下来的粗大β晶粒完全消失,代之以细小的β晶粒,从而消除了板材中“带状组织”等异常组织,再经过适当加工和处理,可获得该合金薄板所要求的细小等轴α+β组织和良好的机械性能。 A simple flattening and unidirectional hot-rolled Ti-6Al-4V alloy slab was used as the test material. The complete β treatment method was used to completely eliminate the coarse β grains inherited from the original ingot and replaced by the fine β grains , Thus eliminating the “band organization” and other abnormalities in the plate, and then properly processed and processed to obtain the required thin equiaxed α + β alloy sheet and good mechanical properties.
