high strain rate compressionflow behaviourdrop weight compression testsThe flow behaviour of 2024 aluminium during drop weight compression tests was investigated. Use of cylindrical specimens of different height to diameter ratios, of different orientations and having undergone varying levels of prestrain,...
High strain rate triaxial-forging(HSRTF) was successfully conducted on three Mg–Zn–Zr alloys by using a pneumatic power hammer. The microstructure evolution and mechanical properties of the forged alloys were investigated. The results show that HSRTF significantly refined the grains due to dynamic...

A modified torsional split-Hopkinson-bar system was used in which a high shear-strain rate can be suddenly imposed on a short specimen while it is being plastically twisted in the opposite sense at a much lower rate. The torsional pulse has a short rise time and a large amplitude, and is...

The results revealed that the dynamic recrystallization (DRX) process was stimulated at high strain rates (ε5s-1) due to the high dislocation density and adiabatic temperature rise. Meanwhile, high nucleation of DRX and low grain growth led to the fine DRX grains. In the strain rate rage of...
The mechanism of deformation changes from simple slip leading to cell formation in the high SFE metal, Cu, to overlapping and/or intersecting deformation twins in low SFE alloy, Cu-4.5%Al. The effect of strain rate is such that it results in rather poorly defined cell boundaries in copper,...

The reason for this behaviour is the intrinsically high reactivity of Os–Ni, which cannot be stabilized at the surface and therefore evolves into the gas product via equation (7) or into unreactive Osubs–Ni species. Hence, the leakage of Os–Ni into the subsurface reduces the rate of ...
