Effect of initial dislocation density on hydrogen accumulation behavior in martensitic steel
, 2020We investigated hydrogen accumulation behavior of martensite structures with different initial dislocation densities. The hydrogen micro-print technique and microstructure observation revealed that the higher initial dislocation density facilitated ...

Yield stresses of ferritic iron pre-deformed at 298 K and 213 K were compared under an identical dislocation density. The specimens pre-deformed at 213 K introduced uniformly distributed dislocations, while those at 298 K formed dislocation cell ...

Low dislocation density AlN on sapphire prepared by double sputtering and annealing
Applied Physics Express, 2020AlN on sapphire with dislocation density of 107 cm−2 was prepared by double sputtering and annealing processes. Full width at half maximum values of X-ray rocking curve for 0002 and 10 1 ¯ 2 diffractions of the AlN films were measured to be 10–20 arcsec ...

Dislocation density-based study of grain refinement induced by laser shock peening
, 2020Laser shock peening (LSP) is an innovative surface processing technique. Grain refinement induced by LSP has been proved to be feasible to improve the surface properties of materials and prolong the service life of metallic components.

Strong and ductile steel via high dislocation density and heterogeneous nano/ultrafine grains
Materials Science & Engineering: A, 2019High strength and high ductility are critical to metallic materials and have always been pursued. A novel strategy to produce a medium Mn stainless steel with high dislocation density and heterogeneous nano/ultrafine-grains was designed and outstanding ...
