چکیده
|
The microstructure and mechanical properties of 7075 wrought aluminum alloy produced by strain induced melt activation (sima) route were investigated.also liquid volume fraction measurement was studied by three procedures. remelting process was carried out in the range of 560 to 610 °c for 20 min holding. the microstructure in the semi-solid state consists of fine spherical solid grains surrounded byliquid.the mechanical properties of the alloy vary with the grain size and weak mechanical properties of globular samples would appear if an alloy reheated at a high temperature. thermodynamic simulation is a fast and efficient tool for the selection of alloys suitable for semi-solid processing.
