Abstract

Structural alloys (Al7175) are widely used in aviation, marine, automobile and aerospace application due to their special characteristics such as high strength to weight ratio, high ductility, light weight, good corrosion resistance, low density, good thermal and electrical conductivity. Improvement in the microstructural, mechanical properties of this alloy can be achieved by homogenization process. Aluminum alloys were subjected to heat treatment to obtain a fine grain structure. Heat treated and as-cast aluminium alloy processed material were characterized using scanning electron microscope, x-ray diffraction, hardness test and erosion test. Material loss in structural materials is aggravated by erosive action and create a massive problem in industrial application such as turbine, agriculture equipment, pumps etc. Study of erosion behaviour on the structural aluminum alloy composite, erosion test of structural aluminum alloy composites was performed at different impingement angle (30º and 90º) and at specified velocity of erodent using erosion test machine (Air Jet Erosion Tester TR-471-800). Investigation was carried out as-cast aluminium alloy Al7175 and homogenized alloys, then set of reading were recorded at 50 m/s velocity of erodent by keeping other parameters like erodent discharge, impingement angle and temperature are variables parameters to obtain the erosion rate.
