Deformation Behavior of Material

The microstructure evolution of Aluminum was investigated in different temperature range. Then the effect of different microstructure on high temperature deformation behavior was further studied. With the aid of scanning electronic microscopy (SEM) the fractography of Aluminum after super plastic deformation was analyzed. The results reveal that intergranular cavities with fine size & homogeneous distribution are beneficial to super plastic deformation. For characterization of material we take material like aluminum. We prepared test specimen having length 32cm, diameter 10mm.The test specimen was installed in the UTM(40T) & loaded in tension. Load-displacement diagram has been plotted for the entire specimen. Then another three specimen each of aluminum have been prepared & they have been kept in the muffle furnace for 30 minutes for a temperature of 200 ,250,300,400 deg. Centigrade. Then the above specimen was installed in UTM & loaded in tension. Then load- displacement diagram have been plotted for above specimen with different temperature .Results were compared with variation of temperature. Then above characterization will be utilized in the various engg. application.
