This study was conducted in order to investigate the influence of plastic deformation on the transformation of retained austenite in a TRIP steel with a high content of Al and a low content of Si. To the aim, appropriate treatments were used to produce the starting material (TRIP steel). The microstructure of the obtained steel was composed of bainite and phases including ferrite and retained a...
One of reasons that researchers in recent years have tried to produce ultrafine grained materials is producing lightweight components with high strength and reliability. There are disparate methods for production of ultra-fine grain materials,one of which is severe plastic deformation method. Severe plastic deformation method comprises different processes, one of which is Parallel tubular chann...
in this paper, the correlation between the surface rumpling and cracking phenomena with twinning mechanism during plastic deformation of hadfield steel has been investigated. the effect of stacking fault energy and the amount of strain are evaluated. the experimental samples with specific amounts of carbon, manganese and aluminum resulting in different stacking fault energies, were produced usi...
