Formatted Abstract/Summary
Stress relaxation tests at predetermined strain/stress were used to assess the athermal stress, σa, component of the flow stress between room temperature and 180°C for Mg-0.8at% Gd, Mg-0.87at% Nd, Mg-1.3at% Y and Mg-2.5at %Al solid solutions. σa decreased monotonically with increasing temperature for the Mg-2.5at%Al whereas it remained constant for Mg-Gd or increased for Mg-Y and Mg-Nd. The limited athermal behaviour of Mg-2.5at% Al alloy can be attributed to the random solid solution introduced by the Al. The remarkably athermal behaviour of the Mg-RE alloys is consistent with an increasingly strong tendency to develop short range order in conjunction with strain induced precipitation hardening.
