High-temperature strength and creep of weld seams of molybdenum alloys in low-cycle loading
- Institute of Strength Problems, Kiev (Ukraine)
We present the cyclic creep and low-cycle fatigue characteristics of the cast weld metal in a weld seam of low-alloy molybdenum alloys TsM6 of the system Mo-Zr-B and TsM10 of the system Mo-Al-B under conditions of high-temperature mild cyclic tension compared with analogous indices for the base metal. We show that the experimental results may be satisfactorily described analytically starting from the concept of equivalent stresses and experimental data on static creep and long-term strength of a material under the corresponding temperature conditions. We have obtained analytical experiments for determination of the equivalent stresses for a trapezoidal load variation cycle based on time and energy criteria for equivalent damage to the material.
