Abstract

The experimental procedure and image analysis for the microstructure and microhardness analysis of aluminum AA 6063 is given. The analysis includes the change of grain size and microhardness in thermo-mechanical history of extrusion. The grain sizes and microhardness are calculated at three different stages of extrusion which are as-cast billet, as-extruded and as-hardened. The whole plan is carried out in three steps. In first step extrusion trials are carried out on AA 6063, in second step grain sizes are calculated and in third step the microhardness are calculated. Optical microscopy and image analysis with Dexel Imaging is conducted to calculate the grain size of AA 6063. For the microhardness calculation Vickers Hardness Tester with Quntimate Imagetech software are used. To study the change in grain size and microhardness, the percentage reduction in grain size and percentage increase in microhardness was presented here. The results of the analysis are given and discuss.
