This study systematically investigated the effects of heat and thermomechanical treatments on pseudo-elastic behavior an Fe-based shape-memory alloy (Fe–17Mn–5Si–10Cr–4Ni-1(V, C) %wt.). First, samples were solution-annealed at 1000 °C for 2 h aged 760 6 h. A treatment was then applied to heat-treated samples. The microstructure mechanical properties (i.e., 0.1% yield stress pseudo-elasticity) c...

Friction stir welding (FSW) is a relatively new welding process that may have significant advantages compared to the fusion processes as follow: joining of conventionally non-fusion weldable alloys, reduced distortion and improved mechanical properties of weldable alloys joints due to the pure solid-state joining of metals. In this paper, a three-dimensional model based on finite element analys...

We investigate a mathematical model for induction hardening of steel. It accounts for electromagnetic e ects that lead to the heating of the workpiece as well as thermomechanical e ects that cause the hardening of the workpiece. The new contribution of this paper is that we put a special emphasis on the thermomechanical e ects caused by the phase transitions. We take care of e ects like transfo...

The thermomechanical behavior of multilayer structures is a subject of perennial interest. Stoney’s formula has long been one of the most important tools for understanding thermomechanical stress for single-layered structures like spin-coated polyimides or deposited metal thin film on substrates. In today’s microelectronics, however, as multilayer substrates have become widely available, the ‘‘...

a dynamic two dimensional problem of thermoelasticity with double porous structure has been considered to investigate the disturbance due to normal force and thermal source. laplace and fourier transform technique is applied to the governing equations to solve the problem. the transformed components of stress and temperature distribution are obtained .the resulting expressions are obtained in t...
