Thermomechanical processes, such as forging, are important steps during manufacturing of superalloy components. The microstructural development processing, which controls the final component properties, is complex and depends on e.g., applied strain, strain rate temperature. In this study, we investigate effect process parameters dynamic post-dynamic recrystallization hot compression Ni-base Ha...

Abstract In alloys where carbides are the main grain boundary phase, role of during hot working is not known. Here, we address effect on dynamic recrystallization compression Ni-base superalloy Haynes 282. When excluding variations from experimental factors neither stress evolution nor final microstructure indicated that exerted a significant influence recrystallization. The carbide solvus temp...

Recrystallization, which can occur dynamically or statically, is an importantphenomenon causing microstructure changes in deformed metals and therefore affecting theproperties of the material. Even though extensive investigations have been carried out on thenumerical modeling of recrystallization, the literature lacks accurate recrystallization modelswhich are able to predict mi...

it is well-known that severe deformation to metals causes a direct grain refinement of the matrix without special heat-treatments due to the mechanism of dynamic continuous recrystallization (dcr). however, the microstructural revolution during severe deformation is seemed to be different depending on the deformation mode, namely the direction of deformation. in general, multi-directional defor...
