The existence of two (low-and high-temperature) extremes of hydrogen embrittlement in heat-resistant austenitic steels and alloys with intermetallic hardening in the range of 293–1073 K was revealed. The low-temperature minimum of their properties in hydrogen is 250–300 degrees higher than that of martensitic and homogeneous austenitic steels. The high-temperature maximum of hydrogen embrittlement...
Purpose: This paper is devoted to the investigation of gaseous hydrogen and ash gas turbine fuel influence on the mass loss in long-term corrosion and mechanical properties of cast heat-resistant blade materials. It has been established that the level of corrosion resistance of the investigated alloys (Ni59Cr21Co10W4Ti3Al3MoLa (SM-104-VI); Ni57Cr16Co12W6Ti4Al3Mo2Hf (SM-90-VI); Ni57Cr16Co11W6Ti4Al4Mo2Hf...
