We conducted systematically tensile tests with a series of Nb-based equiatomic alloys with single-phase, body-centered-cubic (bcc) structure. By subtracting all possible strengthening contributions, the intrinsic strength (or lattice friction stress)

Spherical nanoindentation was performed at room temperature to characterize the time-dependent plasticity behavior of the single-phase CoCrFeMnNi high-entropy alloy (HEA). It was observed that incipient plasticity occurred after a period of waiting t

The superplastic deformation and microstructural evolution of an as processed 8090 Al-Li alloy has been investigated with particular attention to the dynamic grain size refinement and the formation of high angle grain boundaries during concurrent str

The superplastic properties and microstructure evolution of a 0.15%Zr and 0.7%Cu modified 6061 aluminium alloy were examined in tension at temperatures ranging from 475 to 600°C and strain rates ranging from 7 × 10-6 to 2.8 × 10-2 s-1. The refined

Recently, there is a high interest in using light-weight metallic foams (e.g., Al and Mg) for automotive, railway and aerospace applications where weight reduction and improvement in comfort are needed. Metallic foams also have a potential for absorb

Superplasticity in a doubly extruded magnesium based composite, ZK60 reinforced with 17 vol.-%SiC particles, was investigated. The influences of strain rate on the flow stress and elongation in the composite were characterised. It was found that the

Molecular dynamics simulations show significant differences in the deformation mechanisms of nanocrystalline nickel with low- and high-angle boundaries. For the case studied with average grain size of 12 nm, low-angle boundaries present enhanced disl
