摘要

研究了相预转变条件下的热处理模式对钛合金 VT20 电子束焊接接头的结构和性能的影响。结果表明，在 980°C 的温度下进行 120 - 150 秒的热处理可以消除残余应力，将焊接接头的抗拉强度提高到 1230 兆帕，并确保接头体积内的化学成分均匀一致，以满足 OST 1 90013-81 的要求。建议的热处理方法可用于热影响区和焊接接头在空气环境中的局部处理。

Effect of Heat Treatment Modes Under Phase Pre-Transformation Conditions on the Structure and Properties of Electron-Beam-Welded Joints of Titanium Alloy

The effect of heat treatment modes under conditions of phase pre-transformation on the structure and properties of electron-beam-welded joints of titanium alloy VT20 is investigated. It is shown that heat treatment at 980°C for 120 – 150 sec makes it possible to remove residual stresses and to increase the tensile strength of the welded joints to 1230 MPa, as well as to ensure a uniform chemical composition over the volume of the joints to meet the requirements of OST 1 90013–81. The suggested method of heat treatment may be used for local treatment of the heat affected zone and of the welded joint in air environment.
