    Advanced Quantitative Analysis of Dynamic Recovery During Warm Working of FCC Alloys

    By Prantik Mukhopadhyay

    Abstract: Metal working processes of warm working require an advanced quantitative analysis of dynamic and static recovery of dislocations to control microstructures and crucial shape forming properties. Feasibility of dynamic recovery by thermal glide and static recovery by climb of constricted jogs, applicable to ausforming, nano bulk forming by SPD and normalizing has been addressed to design new steels, used for hulls and tribologically superior bearings. Predictive dislocation recovery analysis shows …

    Fabrication of AA5182-Semis for Precise Components

    By Prantik Mukhopadhyay

    Abstract: Al4.5MgMn alloy is known to show an excellent physical and mechanical properties as well as manufacturing and fabrication ease as semis, suitable for making precise components like hull of the light weight vehicles and seamless tubes. Present work has tried to describe the development of microstructure and texture of an industrial tandem hot rolled Al4.5MgMn alloy sheet after laboratory cold rolling and annealing. Crystallographic orientation dependent strengthening rate has been …

    Structure and Cube Texture Development Trend of Al4.5MgMn Alloy at Variable Annealing Conditions

    By Prantik Mukhopadhyay

    Abstract: Hot-rolled Al4.5MgMn alloy was cold rolled to true strain levels 0.8, 1.6 and 2.3. Annealing at 300°C, 350°C and 400 °C was done to develop annealing structure. The annealed structures were measured by SEM-EBSD. The average grain size and grain size distributions were measured using Sigma-scan-Pro 5 structure analysis software. The average grain size and grain size distributions showed higher number frequency of lower annealing grain size with the increase …
