Microstructure and Properties of Trial-produced Large Size TA15 Alloy Bar
-
摘要: 研究了TA15合金试制棒材的组织和性能。结果表明:不同锻造工艺获得的棒材的组织与性能存在显著差异,要获得组织性能均合格的TA15棒材,开坯锻造阶段进行充分镦拔以破碎铸锭原始组织,成品锻造阶段控制锻造温度和变形量是关键。Abstract: The microstructure and properties of TA15 alloy bar were investigated.The results show that there are noticeable differences in the microstructure and properties of TA15 alloy bar produced by different forging processes.In order to obtain desirable microstructure and properties,it is essential that full upsetting and stretching operation should be carried out to break up as-cast structure of TA15 alloy ingot during billet forging,and forging temperature and deformation should also be well controlled when forging finished products.
