Název v původním jazyce

Effect of Heat Treatment on Phase Transformations in Mg-Y-(Nd)-Zn Alloys

Popis výsledku v původním jazyce

Phase transformations during isochronal annealing were investigated in squeeze cast Mg2Y1Zn and Mg2Y1Nd1Zn alloys. Electrical resistivity measurements at 77 K and room temperature, differential scanning calorimetry and microhardness measurements were performed. Transmission electron microscopy and optical microscopy revealed intermetallic phases at grain boundaries and in their vicinity and a relatively high density of stacking faults in grain interiors of both alloys. Resistivity annealing curves showmatrix enrichment by solutes in both alloys during isochronal annealing up to 440 oC. Only a weak precipitation proceeds during isochronal annealing of both alloys. Mechanical properties tested by microhardness measurements do not deteriorate due to theisochronal annealing. If a repeated isochronal annealing of both alloys previously isochronally annealed up to 440 oC is performed, an early precipitation stage appears in both alloys at 80 oC - 200 oC. Thermal stability of microhardness
