In this study, the effect of hot deformation on martensitic stainless steel was carried out in temperatures between 950 to 1100°C and strain rates of 0.001, 0.01 and 0.1 s-1. Two important dynamic recrystallization parameters, the critical strain...

Dynamic recrystallization of the AZ91 alloy was studied by conducting hot compression tests at temperature range of 325–400 ◦C and strain rate of 0.001–1 s−1. The influence of the hot deformation

variables on flow stress as well...

Dynamic recrystallization behavior of austenite in a superaustenitic stainless steel containing 16%Cr and 25%Ni was studied using hot compression tests in a temperature range of 900 ◦C–1200 ◦C and at strain rate of 0.001 s−1– 1s−1. The initiation...

Hot compression behavior of Al6061/Al2O3nanocomposite was investigated in the temperature range of 350−500 °C and the strain rate range of 0.0005−0.5 s−1, in order to determine the optimum conditions for the hot workability ...

performed. The dependency of the peak stress, initial stress, steady state stress, peak strain and dynamic recrystallization on Zener-Holloman parameter was determined. It was shown that the function relating stress and strain rate is generally...

-strain curves showed that dynamic recrystallization is responsible

for flow softening at steady temperatures and strain rates. The relations between peak strain and peak

stress with Zenner-Hollomon parameter, were developed and investigated via...

The as-cast AZ91 Mg alloy ingot with mean grain size of 98 μm after solution treatment was subjected to plastic deformation by multi-pass hot rolling. The process facilitated steady grain refinement by dynamic recrystallization with increasing...

جوش بدون درزی بر روی ورق 2 میلیمتری فولاد زنگ­نزن فریتی 430 با فرایند جوشکاری همزن اصطکاکی با سرعت چرخشی 400 دور بر دقیقه و سرعت پیشروی 50 میلیمتر بر دقیقه ایجاد گردید. مشاهدات ریزساختاری نشان داد که در ناحیه ریزساختاری ...
