Processing, microstructure and creep testing of Pt–Y2O3 composites
چکیده انگلیسی

Two Pt–Y2O3 composites were prepared from recycled wastes by powder metallurgy technique using two different times (8 and 24 h) of low-energy mechanical alloying and their high temperature deformation behaviour was investigated by compressive creep testing at 1200 and 1573 K. The creep strain of the two materials was mutually compared and the role of the milling time was identified. The material milled for 24 h had superior creep resistance due to the better distribution of yttria particles. The microstructure of the Pt–Y2O3 system (material B) was analyzed by optical microscopy, transmission electron microscopy (TEM) and scanning electron microscopy (SEM).
