Conclusions

  1. 1.

    In the heat-affected zones adjacent to a welding seam obtained by argon-arc or electron-beam welding of alloy 36NKhTYu, intermittent decomposition does not occur during aging; this has a deleterious effect on the strength properties and the endurance in cyclic loading of specimens.

  2. 2.

    To eliminate structural inhomogeneity and to improve the strength properties and the endurance of welded joints of alloy 36NKhTYu, it is indispensable, after welding, to carry out a second quenching at 930–1100°C.
