A triplex microstructure of bainite, martensite and retained austenite in the 0.3C-1.4Si-1.8Mn (wt.%) steel was obtained by the bainitic isothermal transformation combined with Q&P process (B-QP process). The effects of bainite morphology and content on the mechanical properties have been studied by controlling the isothermal holding temperature an...

Nonoriented electrical steel of 0.65 mm thickness was sheared to investigate the influence of guillotine clearance on cut-edge damage. The result shows that all the burr, work hardening, and magnetic property damage present an increasing trend initially, then a decrease, followed by an increase with increasing guillotine clearance. In particular, w...

The half-Heusler alloy TiNiSn is a promising material for high-temperature thermoelectric applications due to its good thermal stability and semiconductor-like electrical properties. Numerous synthesis techniques have been utilized to make TiNiSn, but a comparative study on its thermoelectric properties with respect to processing parameters has not...

In this paper, the constitutive modeling and hot deformation behavior of SP-700 titanium alloy was investigated by performing isothermal hot compression tests in the temperature range of 700-950 °C and strain rates of 0.001, 0.1, and 1 s−1. The flow curves of the alloy indicated that the yield point phenomenon occurs at strain rates of 0.1 and 1 s−...

A FeCrCuMnNi high-entropy alloy was produced using vacuum induction melting, starting from high-purity raw materials. The microstructure and mechanical properties of the as-cast FeCrCuMnNi alloy were studied, considering x-ray diffraction (XRD), scanning electron microscopy, and hardness and tensile tests. XRD results revealed the existence of two ...

Ductile damage model has been widely regarded as a valuable method to predict the failure of sheet metal. Based on the thermodynamic theory and continuum damage mechanics, the fully coupled ductile damage model can be developed, which also can better predict the initiation and growth of the fracture. But the identifications of model parameters with...

Contact tube wear is the bottleneck of industrial application for non-copper-coated solid wire. It is crucial that we understand the wear mechanism of contact tube so that we can decrease contact tube wear. The effects of temperature and heat input on contact tube wear were investigated in this work. The results demonstrated that fatigue peeling wa...

The multiscale model of pearlitic transformation, including the finite element solution of the second Fick’s equation with moving boundary in the microscale and Fourier equation in the macroscale, is presented in this paper. According to the mixed-mode approach, both the volume diffusion and the interface mobility were considered. Model describes s...
