The application of hot deformation during Friction Stir Welding (FSW) gives rise to produce a weld nugget consisting usually of dynamically recrystallized grains whose size is substantially lower than that of the base material. In the present study...

to alleviate ridging and enhance the hydroformability.

It was found that grain-scale shear bands were introduced by one-pass TCP, and

texture and microstructure was successfully modified by promoting recrystallization of...

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...

Cold rolling which is one of the most important technique in sheet steel forming causes stretching of microstructure and thus directionality of mechanical properties. This kind of directionality of mechanical properties ...

curves exhibited a peak stress at a small applied strain after which the flow stresses decrease gradually to a steady state flow stress at higher applied strain values representing the occurrence of dynamic recrystallization. Moreover, the material...

) equipped Scanning Electron Microscopy (SEM) and Transmission Electron Microscopy (TEM) are utilized for the microstructural characterizations. Results show that the Continuous Static Recrystallization (CSRX) is the main restoration phenomenon during...

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...
