چکیده مقاله:

In this study, the effect of annealing treatment on microstructure and mechanical properties of Nb-۱۰Hf-۱Ti wt.% produced by Spark Plasma Sintering (SPS) was investigated. Scanning electron microscope (SEM), optical microscopy, X-ray diffraction analysis, hardness, and uniaxial tension test were used. Annealing treatment was carried out in a vacuum of ۱۰-۳ Pa at ۱۱۵۰ °C for ۱, ۳, ۵, and ۷ hours and in an argon atmosphere at ۱۳۵۰ °C for ۵ hours. Internal oxidation and subsequent hafnium oxide formation causes the hardening of the C۱۰۳ alloy and drastically increases hardness and tensile strength. Although HfO۲ particles formed in the grain boundary cause brittleness and cleavage fracture of samples. Volume fraction, particle size, and mean interparticle spacing of oxides significantly change by annealing and subsequently the mechanical properties are affected. The SPSed sample at ۱۵۰۰ ℃ is softened by annealing at ۱۱۵۰ ℃ for ۵ hours and its hardness and yield strength are reduced from ۳۰۳ Hv to ۲۳۰ Hv and ۵۳۸ MPa to ۴۹۰ MPa respectively. While annealing at ۱۳۵۰ ℃for ۵ hours increases hardness and yield strength increases to ۳۴۳ Hv and ۵۸۱ MPa.
