This chapter reports the discovery of a hitherto unknown strain hardening mechanism, which
is intrinsic to the gradient structure in an engineering material. The gradient structure shows …

Additively Manufactured (AM) metallic alloys differ from their conventionally produced
counterparts by complex multi-scaled microstructures leading to deeply modified …

The deformation micro-mechanisms of an as-cast equimolar refractory high-entropy alloy
composed of Ti, Zr, Hf, Nb and Ta are analyzed by monotonic and relaxation compression …

The impact of a concentrated solid solution on the deformation mechanisms of a bcc multi-
principal elements alloy is investigated. The room temperature mechanical properties in …

The objective of this work is to study the effect of grain refinement using equal channel
angular pressing with parallel channels (ECAP-PC) on microstructure, mechanical …

Stress-relaxation experiments were performed on nanotwinned Cu to characterize the twin
size-dependence of the activation volume and mobile dislocation density. We find that the …

Microstructural analysis and mechanical testing have been performed on two types of
nanocrystalline (NC) Ni samples and compared to coarse-grained (CG) Ni. The NC …

Constitutive equations are constructed for single-crystal nickel-based superalloys. Account
is taken of dislocation glide in the channels of the matrix phase (referred to as γ) of the face …

With recent advances in computational modeling and in situ transmission electron
microscopy (TEM) technologies, there have been increased efforts to apply these …

A quantitative model for the peak temperature in work-hardening in L12 intermetallics is
proposed. It is based on the competition between the exhaustion of mobile dislocations by …
