Severe plastic deformation (SPD) is a common method to fabricate nano-grained metals.
However for Zr, a structural metal for nuclear applications, obtaining a nanoscale grain …

A large-grained Nb polycrystal was successively uniaxially compressed to different
cumulative strains to study the evolution of both the microstructure and the orientation of …

In response to temperature or pressure changes, many body-centered cubic (bcc) materials
undergo martensitic bcc-hcp phase transformation, which is known to produce rich …

Local fluctuations in the chemical composition of high-entropy alloys (HEA) are known to
have a significant influence on their mechanical performance. In this work, we conclusively …

The Ti–25Nb–3Zr–3Mo–2Sn (wt.%) alloy deforms primarily by {3 3 2}< 1 1 3> twinning with
limited {1 1 2}< 1 1 1> twinning and stress-induced phase transformations. For the Ti–25Nb …

The crystal orientation of body centered cubic (bcc) precipitates embedded in hexagonal
close packed (hcp) matrix is usually assumed to follow the so-called Burgers orientation …

Twinning in coarse-grained Zr is ubiquitous but not in nanostructured Zr due to the strong
nano-confinement. Here we show that hexagonal close-packed (hcp) twins can proliferate in …

Interface-dominate properties can be strengthened when the interface spacing is further
reduced to nanoscale dimensions. To analyze the dominant deformation modes in α-Zr …

We report ab initio study of the formation of chemically ordered athermal ω phase (trigonal
symmetry, space group, non-ideal ω, ω′) in Zr3Al2Nb and (trigonal symmetry, space group …

Zr is a hexagonal close packed metal which shows great anisotropy during deformation. To
reveal the effect of initial orientations on deformation behaviors of Zr alloys at elevated …
