Cr-Mn-Si alloyed high-strength steel was subjected to deep cryogenic treatment after quenching and tempering (Q-T), the microstructure property evolution of alloy were studied. The tensile strength increased by about 30 MPa, yield decreased 10 grains refined, indicating that toughness can be relatively improved via (−120 °C × 1 h); secondary carbides precipitated inside martensitic matrix unifo...

Deep cryogenic treatment has shown promise as a facile method of increasing the characteristics many materials including alloys iron, aluminum, and magnesium. However, there have not been any prior studies on its effect microstructure thermal mechanical properties magnesium-based nanocomposites. In this study, Mg/2wt.%CeO2 nanocomposite was processed using disintegrated melt deposition processi...
