Unusual strain hardening response and ductility of NiCoCr equiatomic alloy were investigated through microstructural analysis of [111], [110] and [123] single crystals deformed under tension. Nano-twinning prevailed at, as early as, 4% strain along t

In this work, we statistically studied the activation and suppression of 〈c + a〉 dislocations in a textured Mg–3Al–1Zn alloy after compression. Our results revealed that the activation and suppression of 〈c + a〉 dislocations in polycrysta

The orientation dependence of tensile deformation in Fe40Mn40Co10Cr10 high entropy alloy (HEA) was investigated in [111], [001] and [123] oriented single crystals. Transmission electron microscopy investigations revealed three major mechanisms contro

A newly developed ultra-high strength martensitic steel, AF9628, has generated academic and industrial attention due to its combination of high yield strength and ductility at a low cost. Several studies have demonstrated that this steel can be succe

The damage tolerance approaches to fatigue rely on fracture mechanics concepts to explicitly account for the fatigue crack growth process. These approaches typically adopt the Paris equation, which relates the crack growth per cycle to the range of v

Severe plastic deformation (SPD) leads to substantial strengthening in materials via grain refinement, however, the main drawback of the materials processed using known SPD techniques is the lack of uniform plastic deformation due to low strain harde
