Abstract:

Small punch test was used to evaluate the properties of light alloys in various directions. Three different materials were studied: (i) magnesium alloy WE54 prepared by a powder metallurgical route with final hot extrusion, (ii) aluminium alloy reinforced with 20 vol. % of Saffil fibres with planar orientation, and (iii) Al-Al₄C₃ composite prepared by mechanical alloying and subjected to equal channel angular pressing as a final step. Tests were performed under constant force at elevated temperatures. The observed orientation dependence of creep properties is strongly material dependent. The results confirm the feasibility of the small punch test for determination of anisotropy of mechanical properties.
