Abstract High-entropy alloys (HEAs) have become a research focus because of their easy access to nanostructures and the characteristics high strength, hardness, wear resistance, oxidation been applied in aerospace lightweight materials, ultrahigh temperature high-performance biomimetic materials. At present, study HEAs mainly focuses on microstructure mechanical properties. Mo, Ti, V, Nb, Hf, T...
The effect of microstructure and dispersion secondary phases on tensile mechanical properties two high nitrogen austenitic stainless steels subjected to annealing or rolling at 1000 °C was studied. solid solution strengthening gave the main contribution overall strength after annealing. Similar provided by dislocation density that resulted in almost twofold increase yield strength.
Strength and ductility are mutually exclusive if they are manifested as consequence of the coupling between strengthening and toughening mechanisms. One notable example is dislocation strengthening in metals, which invariably leads to reduced ductility. However, this trend is averted in metastable austenitic steels. A one-step thermal mechanical treatment (TMT), i.e. hot rolling, can effectivel...
