The work carried out by the authors over the last decade on the processing, microstructural characterization and the mechanical behaviour of Mg alloys is reviewed. In particular, the potential for grain refinement and for the development of specific textures of large strain hot rolling (LSHR), equal channel angular pressing (ECAP) and accumulative roll bonding (ARB) is discussed. The recrystall...

Due to a combination of advantages, high-performance steel components, especially for automotive manufacturing applications, are generally forged parts. In the forging industry, bainitic steels being increasingly used, because they can reduce processing chain and energy consumption. this case, microstructure be obtained immediately after forging, with controlled cooling, without any subsequent ...

Twinning-induced plasticity (TWIP) steel is a second-generation advanced high strength grade developed for automotive applications. TWIP steels exhibit an excellent combination of and ductility, mainly originating from the activation deformation twinning. However, generally relatively low yield (YS), which limits their practical Thus, developing YS without ductility loss essential to increase i...

In the present investigation the disturbances in a homogeneous transversely isotropic magneto-Visco thermoelastic rotating medium with two temperature due to thermomechanical sources has been addressed. The thermoelasticity theories developed by Green-Naghdi (Type II and Type III) both with and without energy dissipation has been applied to the thermomechanical sources. The Laplace and Fourier ...

In recent years, short pulsed laser materials interaction has attracted considerable attention owing to the rapid development of short pulsed lasers and their potential applications in laser-material processing. In this work, molecular dynamics (MD) simulations are conducted to study the thermal and thermomechanical phenomena induced by picosecond laser heating. The generation and propagation o...

Polyetherimide (PEI) blends modified by either polycarbonate (PC) or polyethylene terephthalate glycol-modified (PETG) were prepared. The latter modifier (PETG) was an industrial grade widely used for fused deposition modelling (FDM) printing. PEI blends were compared to Ultem 9085, which is the standard PEI grade for FDM printing in advanced applications. All the blends were thoroughly charact...

The feasibility of using ‘‘grain-boundary engineering” techniques to reduce the susceptibility of a metallic material to intergranular embrittlement in the presence of hydrogen is examined. Using thermomechanical processing, the fraction of ‘‘special” grain boundaries was increased from 46% to 75% (by length) in commercially pure nickel samples. In the presence of hydrogen concentrations betwee...
