【摘要】 研究了形变热处理对 TA15钛合金组织与力学性能的影响。在α+β两相进行形变热处理使组织中的条状初生α相碎化。对水冷的试样进行930℃/1h/空冷+915℃/1h/空冷+530℃/6h/空冷的处理,抗拉强度明显提高,组织中的条状初生α相发生球化。在β相进行形变热处理使强度略有降低,魏氏组织中的α层片增厚。更多还原

【Abstract】 The effects of thermomechanical treatment on microstructure and mechanical properties of TA15 titanium alloy were studied. Thermomechanical treatment in α+β zone makes the strip primary α phase broken.After heat treatment of 930℃lh/AC+915℃ /lh/AC+530℃/6h/AC for the water cooled samples,the tensile strength is apprently increased and the strip primary α phase is spberoidized.Thermomechanical treatment in β zone causes the tensile strength decreased slightly and the α lamellas in Widmanstaten become thicker.更多还原
