Mechanical properties of nanostructured 316LVM stainless steel annealed under pressure

Effect of applied pressure on microstructure development and homogeneity in an aluminium alloy processed by high-pressure torsion

“…Thus, a high pressure will reduce the rate of dynamic recovery by diffusioncontrolled mechanisms and this will increase the accumulation of dislocations and enhance the efficiency of grain refinement [15,60]. Under higher applied pressures, the generation of point defects will be suppressed since it is associated with an increase in volume of the material [61]. Also, the energy of forming dislocations increases where this is due to the changes in the shear modulus G, the Poisson's ratio ν and the Burgers vector, b.…”

Microstructure, mechanical and corrosion properties of friction stir welded high nitrogen nickel-free austenitic stainless steel

“…High density dislocations in the SZ generated by mechanical deformation were the key factor decreasing the percentage of elongation [43]. In addition, the presence of less amount and small size of Cr 23 C 6 carbides exhibits a certain extent effect on the decrement of percentage of elongation [44].…”

Recrystallization and grain growth of a nano/ultrafine structured austenitic stainless steel during annealing under high hydrostatic pressure

“…Nevertheless, one issue which remains almost completely neglected is how such materials behave during annealing under high hydrostatic pressure. This subject has been raised only in the author's previous work [14,15]. In those studies, annealing under high hydrostatic pressure was applied to a hydrostatically extruded (HE) austenitic stainless steel to optimize its mechanical properties, particularly its strength to ductility balance.…”
