TB10钛合金的焊接组织与性能Microstructure and mechanical properties of TB10 titanium alloy after welding
研究电子束焊接态TB10钛合金的显微组织和力学性能。结果表明：TB10板材焊区经过固溶及双重时效后，可得到较好的强度配合以及优异的显微组织和力学性能；焊接和焊接前的热处理工艺使焊区的抗拉强度、屈服强度和塑性均有所下降；经过(725 ℃, 1 h, FC)固溶处理后经双重时效处理后，焊区的冲击断裂韧性达到31.3~45.6 J/cm2；固溶+双重时效处理后，合金基体和焊区的显微组织由β相、粗大的初生α相、短小细长的针状次生α相组成；热处理后，合金元素在不同相中的重新分布使各相变得更加稳定。
The microstructure and mechanical properties of electron beam welding of TB10 titanium alloy were investigated. The results show that, after solution treatment and twice aging treatment, the weld zone of TB10 plate obtains the best combinations of strengths, and showing excellent microstructure and mechanical properties. The processing of weld and post weld heat treatment decreases the tensile strength, yield strength and ductility of weld zone. After (725 ℃, 1 h, FC) solution treatment and twice aging treatment, the weld zone impact toughness is 31.3−45.6 J/cm2. After solid solution treatment and twice aging treatment, the microstructures of the base metal and weld consist of toughness β phase, coarsening primary α phase, short and minimum needle-shape secondary α phase. After heat treatment, alloy elements redistributions in different phases of alloy become more stable than before.
