Sažetak
The paper presents the data on some cyclic creep and low-cycle fatigue characteristics of the cast weld metal of joints formed by welding low-alloyed molybdenum alloys (Mo-Al-B, Mo-Zr-B, and Mo-Re). The data have been obtained in high-temperature cyclic tension and compared with the similar parameters of the base metal. It has been shown that the experimental data obtained can be satisfactorily described by analytical expressions using equivalent stresses and data of static creep and long-term strength tests for the analogous temperatures. Some analytical expressions for stresses equivalent to those for a trapezoidal loading cycle have been derived on the basis of the time-dependent and energy-based criteria.
