The effects of total deformation on the microstructure and room temperature tensile properties of BT-20 alloy plate were studied in α+β.
主要研究了在α+β区总变形量对BT-20钛合金厚板组织与性能的影响,获得了在两相区总变形量控制在71%、85%和91%生产出的三种规格厚板在相同热处理制度下的显微组织以及所对应的室温力学性能。
Based on the experiment,the elongation of the cladding sheet can be reached 50%～65% when the total deformation rate is 18%～20% and the heating temperature is 460～480℃.
