Magnesium Based Composite via Friction Stir Processing

Abstract

Friction stir processing (FSP) was used to incorporate 6 vol.% of micron sized B4C (6 micrometer) reinforcements in WE43 alloy to form a surface composite. Multiple passes were utilized in order to achieve homogenization. Better distribution of the reinforcements, grain size refinement and an increase in hardness was observed after every FSP pass. The composite was 4 6 mm thick and showed higher values of hardness and modulus than that of the base material. Post FSP aging was performed at 210 deg C for 48 h. The tensile properties were evaluated at room temperature for samples in as-FSP and after FSP+aging. The yield strength remained unaffected by the reinforcement addition.
