The methods of optical microscopy, x-ray phase analysis and microindentation are used to study the effect of vacuum annealing at 750, 800 and 850°C on the structure, phase composition and microhardness characteristics over cross section of welded joints of unlike alloys OT4 – VT6, VT20 – VT6 and VT23 – VT6. Recommendations are developed on the temperature of vacuum annealing of the welded compositions studied, which provide gradual variation of the hardness parameters in welded joints upon transition from the matrix metal of one alloy to the other.

钛合金焊接接头的真空退火 OT4 – VT6、VT20 – VT6 和 VT23 – VT6

采用光学显微镜、X射线相分析和显微压痕等方法研究了750、800和850°C真空退火对不同OT4合金焊接接头横截面组织、相组成和显微硬度特性的影响。 VT6、VT20 – VT6 和 VT23 – VT6。对所研究的焊接组合物的真空退火温度提出了建议,当从一种合金的基体金属过渡到另一种合金时,焊接接头的硬度参数逐渐变化。
