The presented work is focused on the investigation of dilute Mg-Zn-Y alloys prepared by the consolidation of rapidly solidified ribbons. Particularly, the influence of both amount of the Zn and Y alloying elements (varies between 1 and 2 at.%) and th

Stress-relaxation tests were performed during plastic deformation at room temperature of three magnesium Mg–Li alloys reinforced with 10 vol% of short Saffil fibers. For comparison, the composite with the Mg matrix was studied. The time dependencie

AX61 magnesium alloy was reinforced with short Saffil fibres using squeeze cast technology. Samples were cut from the casting in two directions: parallel and perpendicular to the fibre plane. Samples were deformed in compression at various temperatur

An AX52 magnesium alloy (nominal composition Mg-5Al-2Ca in w.%) was submitted to equal channel angular pressing (ECAP) using processing route A; 1–8 passes through the ECAP tool were applied. The thermal conductivity of the ECAP samples was measure

Accumulative roll bonding (ARB) is one of the methods of severe plastic deformation which is relevant for industrial production of sheets. While mechanical properties of several magnesium alloys subjected to the ARB process have been studied, the phy

The amplitude-dependent internal friction of continuously-cast and rolled AZ31 magnesium alloy was measured in this study. Samples were annealed and quenched step by step; immediately after the treatment, the amplitude dependence of the logarithmic d

This letter presents a systematic study of serrated flow of the FeAlCrMo medium-entropy alloy in compression, first observed at 400 °C and a strain rate of ~10−4 s−1. In this work, these parameters were varied in order to evaluate how they affec
