Název v původním jazyce

Thermal stability and creep behaviour of MgNiYCe-rich mischmetal alloys processed by a powder metallurgy route

Popis výsledku v původním jazyce

The thermal stability and creep behaviour of MgNi2Y1CeMM1 and MgNi3Y1.5CeMM1.5 alloys have been investigated at 523 and 623 K. Both alloys were processed by a powder metallurgy route involving rapid solidification of powders, cold isostatic pressing andextrusion at 673 K. The microstructure of both alloys was studied in the as-extrusion condition and after thermal treatments at 523 and 623 K up to 500 h. Mechanical characterization was carried out by hardness measurements in samples annealed at 523 and623 K and stepwise stress compressive creep tests at these temperatures. Results have shown long-term stability of the microstructure after annealing at 523 K in both alloys and hardness values remained constant along all treatment.
