Abstract: The tensile performance of a novel dilute Mg-Ca-Y-Zn-Mn alloy processed by rapidly solidified ribbon consolidation (RSRC) technique was investigated in situ by X-ray diffraction using synchrotron radiation. Moreover, the same study was performed on specimens annealed at 300 and 400 °C for 2 h after RSRC processing. It was found that annealing at 300 °C had no considerable influence on the microstructure and, thus, on the tensile performance. On the other hand, the heat treatment at 400 °C yielded an increase in the recrystallized material fraction and the average grain size, coarsening of the secondary Mg$_2$Ca phase particles as well as a decrease in the intensity of $(10\bar{1}0]$ fiber texture. The latter effect caused twinning during tension which contributed to the increase in strain hardening with increasing strain. Due to the texture, mostly non-basal < a > dislocations developed during tensile testing. The interaction between the dominant prismatic < a > dislocations can result in immobile dislocations, which can contribute to the enhanced hardening observed at higher strains.
