Webb24 juni 2024 · The influence of wall thickness and specimen surface on the creep behavior of the single-crystal nickel-based superalloy MAR M247LC is studied. Specimens with wall thicknesses of 0.4, 0.8, 1 and 2 mm, with and without casting surface, are compared to specimens of the same wall thickness prepared from bulk material. Creep behavior … Webb10 apr. 2024 · Thermal creep tests were conducted on diffusion-welded Alloy 800H tubes at 700 °C under various hoop stresses between 70 and 140 MPa using an in-situ creep measurement system. The tube-type creep specimens obtained from diffusion-welded Alloy 800H plates at 1150 °C and 10 MPa for 2 h achieved a uniform thickness with only …

WebbThe increased thermal efficiency of fossil power plants calls for the development of advanced creep-resistant alloy steels like T92. In this study, microstructures found in the heat-affected zone (HAZ) of a T92 steel weld were simulated to evaluate their creep-rupture-life at elevated temperatures. An infrared heating system was used to heat the … Webb18 dec. 2024 · creep rupture time of both Co-modified steels is significantly longer in comparison with ... obvious that the influence of W content on the stability of TMLS under long-term creep conditions is. swanwick hall school term times
