Blended Elemental P/M Synthesis of Titanium Alloys and Titanium Alloy-based Particulate Composites
Hagiwara Masuo,Emura Satoshi 한국분말야금학회 2006 한국분말야금학회 학술대회논문집 Vol.2006 No.1
Titanium alloys and Titanium alloy-based particulate composites were synthesized using the blended elemental P/M route. First, processing conditions such as the fabrication of master alloy powder were investigated. Ti-6Al-4V, Ti-5Al-2.5Fe, Ti-6Al-2Sn-4Zr-2Mo, IMI685, IMI829, Timetal 1100 and Timetal 62S, and Ti-6Al-2Sn-4Zr-2Mo/ 10%TiB and Timetal 62S/10%TiB were then synthesized using the optimal processing conditions obtained. The microstructures and mechanical properties such as tensile strength and high cycle fatigue strength were evaluated.
Low Cost Synthesis and Property Evaluation of P/M Ti Alloys and Ti - Based Particulate Composites
KIM, Sung Joon,Hagiwara, Masuo 대한금속재료학회(대한금속학회) 1998 METALS AND MATERIALS International Vol.4 No.2
Ti-6Al-4V alloy and Ti-6Al-2Sn-4Zr-2Mo/10TiB particulate composites were synthesized using; a blended elemental powder metallurgy processing route. Microstructures and mechanical properties, such as tensile, creep, Young's modulus and high-cycle fatigue-strength were evaluated. Special attention was paid to improve the high-cycle fatigue-strength of these two materials by modifying the matrix microstructure or process innovation. The fatiguecrackinitiation mechanism, relationship between a-phase morphology and high-cycle fatigue-strength, and other factors contributing to the increase in fatigue strength were analyzed.
