RESPONSE OF SQUEEZE-CAST Mg-Y-Nd-Sc-Mn ALLOY TO ANNEALING WITH CONSTANT HEATING RATES
Original language description
The MgYNdScMn alloy was squeeze-cast under a protective atmosphere. Precipitation reactions were studied by differential scanning calorimetry. Additionally the electrical resistometry and hardness measurements were performed. Transmission electron microscopy of specimens quenched from temperatures of significant thermal changes were used to identify microstructural processes responsible for these changes. The measurements revealed three exothermic effects connected to complex precipitation processes. Nodirect evidence was observed for the first effect. As this early stage is associated with small resistivity and hardness changes, we suppose a submicroscopic formation of a transient beta'' phase there. Precipitation of the transient beta' phase in theform of fine plates was observed at 270 oC. A weak thermal reaction corresponding to this process was detected only for heating rates of 1 and 5 K/min. The I' phase subsequently transforms into the stable I phase. Discs of the Mn2Sc phase
