Comparison of Oliver-Pharr and Work of Indentation Approach to Determine the Mechanical Properties of Melt-Spun Al-12%Wt.Si-0.5%Sb Alloy

In this research, the hardness and reduced modulus of Al-%wt.12-%wt.0.5Sb melt-spun alloy were evaluated by using depth sensing indentation atomic force microscopy techniques. We considered two approaches, Oliver-Pharr Work Indentation, to analyse load-displacement curves. The ratio final maximum was found be higher than reported critical value 0.70, which mean that pile-up dominant in melt-spun. A around deformed surface observed from microscope, is consistent with aferomentioned result. calculated method Indentation Approach. According results, Approach more reliable approach because reducing affect.
