Fracture Surface Characterisation of Friction Stir Processed Magnesium Alloy after Mechanical Tests EMANUELA CERRI1*, MARIA TERESA DI GIOVANNI1, TIZIANO RIMOLDI2 and LUIGI CRISTOFOLINI2 1Department of Industrial Engineering, University of Parma, Campus Area delle Scienze 181/A, 43124 Parma (ITALY) 2Department of Physics and Earth Sciences, University of Parma, Campus Area delle Scienze n.7/A, 43124 Parma (ITALY) Keywords: FSP, magnesium alloy, fracture surface, mechanical properties.
A high pressure die cast Mg-9%Al-1%Zn alloy was friction stir processed at two high rotation rates and advancing speeds.
Microhardness was measured on cross sections perpendicular to the advancing direction of the stirring pin, at various depth levels, before performing tensile tests to estimate the attitude of a single region to be deformed.
The indentations run from the base material (BM) to the stirred zone from the advancing to the retreating side.

From these results, an advanced stem having high strength at the necked part can be developed for a new artificial hip joint, keeping low Young's modulus at the distal part implanted in a femur.
Based on the obtained results we propose a fabrication method of the advanced stem as follows.
As a result, the advanced stem with high strength at the necked region and low Young's modulus at the distal region is produced with gradation of mechanical properties between both the edges.
This mechanical properties gradation is applicable to an advanced stem of an artificial hip joint, which has high strength at the necked region and low Young's modulus at the distal region.
