In hot forming process, the workpiece undergoes plastic deformation at high temperature and the microstructure of the workpiece changes according to the plastic deformation. These changes affect the mechanical properties of workpiece. In order to optimize this process, both the plastic deformation of workpiece and its microstructural changes should be taken into consideration. Since material be...
Background Cardiac diffusion tensor imaging (cDTI) by cardiovascular magnetic resonance is becoming more robust for clinical imaging. It has the potential to assess microstructural changes, such as disarray in hypertrophic cardiomyopathy, through measures of fractional anisotropy (FA) and mean diffusivity (MD).[1] However, normal variation in regional and transmural FA and MD is not well descri...
the mechanical properties and microstructural developments of 321 stainless steel during thermomechanicalprocess were investigated. the repetitive cold rolling and subsequent annealing wereconducted to achieve nanocrystalline structure in an aisi 321 stainless steel. heavily cold rolling at−20°c was conducted to form martensite in metastable austenitic steel. the process was followed byannealin...
