The microstructures and tension properties of Fe50Mn20Cr20Ni10 medium entropy alloy (MEA) were investigated,which was produced by vacuum induction melting and subsequently was homogenized at 1200 ℃ for 6 h.Microstructure characterization shows the single-
Effect of vanadium content on microstructure and properties of in situ TiC reinforced VxFeCoNiCu mul
VxFeCoNiCu high entropy alloy matrix composites reinforced by in situ TiC particles (10 vol.％),i.e.,VxFeCoNiCu/TiC composites,were fabricated from V-Fe-Co-Ni-Cu-Ti-C system using vacuum inductive melting method.With the content of vanadium increasing,the
T23 steel (2.25Cr-1Mo-1.6W-0.24V-0.05Nb,in wt.％) has been widely used as water walls in ultra-supercritical (USC)power plants.However,high reheat cracking susceptibility of T23 steel hazarded the safety of USC power plants.It is aimed to improve the rehea
Modified artificial neural network model with an explicit expression to describe flow behavior and p
The elevated-temperature deformation behavior of Ti2AlNb superalloy was observed by isothermal compression experi-ments in a wide range of temperatures (950-1200 ℃) and strain rates (0.001-10 s-1).The flow behavior is nonlinear,strongly coupled,and multiv
