Abstract: Isothermal compression tests of BSTMUF601 super-alloy in the temperature range of 950 ̋C–1200 ̋C and at the strain rates of 0.2 s ́1, 5 s ́1, 10 s ́1 were performed on a Gleeble-1500D thermo-mechanical simulator. Based on the hyperbolic sine function, the unified constitutive equations and hot processing maps during the hot deformation process were established. The flow stress predicted by...

The hot deformation behavior of a high carbon carbide-free bainitic steel was studied through isothermal compression tests that were performed on a Gleeble-1500D thermal mechanical simulator at temperatures of 1223-1423 K and strain rates of 0.01-5 s-1. The flow behavior, constitutive equations, dynamic recrystallization (DRX) characteristics, and processing map were respectively analyzed in de...

Isothermal interrupted hot compression tests of 5754 aluminum were conducted on a Gleeble-3500 thermo-mechanical simulator at temperatures of 350 °C and 450 °C, and strain rates of 0.1 s−1 and 1 s−1. To investigate the metadynamic recrystallization behavior, a range of inter-pass delay times (5–60 s) was employed. These tests simulated flat rolling to investigate how softening behaviors respond...

In this study, the influence of multi-step heating methods, such as two-step methods and three-step on properties Al–Si coating boron steel sheet were evaluated by using Gleeble-3500 thermal simulator. The evolution microstructure 3D surface topography also investigated. results showed that rates 50 °C/s, named rapid heating, at stage 20–500 °C did not significantly in methods. indicated volume...

The effect of post-weld heat treatment (PWHT) temperature on the mechanical properties heat-affected zone (HAZ) 2.25Cr-1Mo steels was investigated. SA-387 Gr. 22 Cl. 2 steel employed, and specimens taken from were thermally cycled using Gleeble to simulate coarse-grained HAZ (CGHAZ), fine-grained (FGHAZ), intercritical (ICHAZ). Before PWHT, simulated HAZs exhibited poor impact toughness as comp...

The automotive industry is interested in manufacturing components with tailored mechanical properties. To this end, advanced heating treatments can be exploited to obtain the so-called Tailored Heat-Treated Blanks (THTB). However, properties are strongly affected by process parameters of treatments, which require a preliminary design. Physical simulation decisive tool phase useful information a...

Titanium alloys exhibit mechanical and physical properties that fit structural applications demanding light-weight, corrosion resistance and biocompatibility. Ceramic reinforcements can further improve some of these mechanical properties, such as wear resistance, specific stiffness and specific strength. In comparison to continuous reinforced titanium alloys, the particle reinforced alloys (PRT...

Hot deformation behavior of the Cu-Cr-Zr-Nd alloy was studied by hot compressive tests in the temperature range of 650-950 °C and the strain rate range of 0.001-10 s(-1) using Gleeble-1500D thermo-mechanical simulator. The results showed that the flow stress is strongly dependent on the deformation temperature and the strain rate. With the increase of temperature or the decrease of strain rate,...
