On the phase stability of MARM247LC alloy during long term thermal exposure
Journal of Materials Research and Technology, 2023 The microstructures stability of directional-solidified (DS) MarM247LC alloy were investigated during thermal exposure at 800–950 °C up to 5000 h. In the dendrite core (DC), the particle size distribution (PSD) of γ′ phase shows that the coarsening ...

Strain-induced precipitation behaviors of 7Mo super-austenitic stainless steel
Journal of Materials Research and Technology, 2023 Strain-induced precipitation (SIP) behaviors of 7Mo super-austenitic stainless steel (SASS) were studied by strain relaxation test at 850 °C. Our results reveal that sigma (σ) phases are the predominant SIP of 7Mo SASS, with the chemical formula of (FeNi)
