Abstract

This research is to study the material properties of low density alloy after the heat treatment process. Low density alloy is category of alloy that have densities below that 4.5g/cm³. The alloys consist in this category are magnesium, titanium, beryllium and aluminium. In this study, the alloy used are titanium alloy, Ti6Al4V and magnesium alloy, MgAZ91D. These alloys will undergo the heat treatment process at various different temperature. Heat treatment temperature of Ti6Al4V are 950°C/4H and 900°C/4H. While, for MgAZ91D are 500°C/8H and 450°C/8H. Then, followed by water and air quenching medium and aging treatment at 400°C/4H for Ti6Al4V and 200°C/8H for MgAZ91D. The effect of the heat treatment parameter is documented by compared surface roughness, optical microscope analysis and hardness measurement with as-received materials. The results shows that heat treatment process with water quenching medium help to improve properties of material Ti6Al4V and MgAZ91D in term of grain size of microstructures. Generally, the value of surface roughness and hardness increased after the heat treatment process.
