Abstract

Low-alloy molybdenum alloys are widely used in high-duty welded structural parts and power units that operate under conditions of extremely high temperatures and loads in aggressive gas media. In some cases, in particular in storing and transporting the parts, they are subjected to cyclic and vibration loads, which may cause their fatigue and premature failure. The present paper gives the results of a study of the fatigue resistance of thin rolled sheets and welded joints of molybdenum alloys TsM-6 and TsM-10 with allowance for the structural state of the material and the factors of the manufacturing process, particularly the heat treatment regime.
