Purpose: of this paper is to give information on the deformation behaviour of ZC63 magnesium alloys reinforced with 10 vol. % of SiC particles. Design/methodology/approach: The deformation behaviour of the ZC63/10SiCp composite was investigated in tensile tests over the temperature range from 23 to 200 °C at an initial strain rate of 8.3 x 10 ^-3 s ^-1. Findings: The flow stress decreases with increasing temperature. Both the yield stress and the maximum stress decrease with increasing temperature for temperatures higher than 100 °C. Research limitations/implications: The paper indicates significant softening mechanisms that take place at high temperature deformation. Practical implications: The ZC63/10SiCp composite may be used for applications at temperatures above 100 C. Originality/value: New results on the temperature dependence of the yield stress and maximum stress were obtained.
