The hot deformation characteristics of M50 steel in the temperature range 900–1150 °C and strain-rate 0.01–10 s−1 was investigated this study using a Gleeble-3800 thermal simulation testing machine. true stress–strain curves showed that resistance increased with decreasing temperature, increasing strain rate before peak stress reached. After stress, dynamic reversion occurred, consequently, dec...

Continuous cooling transformation (CCT) diagrams of base metals are common in welding. They can be built using physical or numerical simulations, each with advantages and limitations. However, those not usual for weld metal, considering its variable composition due to the dilution into metal. Wire Arc Additive Manufacturing (WAAM) is a distinctive case which interest materials comparable raises...

Two as-cast low-density steels grades (austenite-based duplex Fe-30.9Mn-4.9Al-4.5Cr-0.4C and austenitic Fe-21.3Mn-7.6Al-4.3Cr-1C) with an initial dendritic microstructure were subjected to hot working conditions understand the influence of deformation parameters on flow behavior microstructural evolution. The alloys produced using electric arc melting, their phase constituents determined optica...

The main contribution of the present work is to investigate the capability of exponential-type constitutive equationto model the warm deformation flow curves of a eutectoid steel in the temperature range of 620-770 °C andat the strain rates in the range of 0.01-10 s-1 conducted on a Gleeble-1500 thermomechanical simulator. Warmdeformation in this temperature range f...

AA6010 in the F temper was investigated using a Gleeble 3800 test rig across range of temperatures (350–550 °C) and strain rates (1 × 10?1 s?1 1 101 s?1) to identify optimal forming conditions. Post-forming electron back-scattered diffraction analysis conducted mechanisms responsible for material formability. Optimal conditions were observed be 500 °C rate s?1, with clear evidence dynamic recry...
