Microstructure and grain boundary morphology evolution of a novel Co–9Al–9W–2Ta–0.02B alloy doped with yttrium

Effect of doping Mg on the microstructure and mechanical behaviours of a novel Co-9Al-4.5W-4.5Mo-2Ta-0.02B alloy at room- and high-temperatures

“…Micro-alloying, i.e., alloy addition of generally less than 1 at.%, is probability the most effective approach to improve the properties mainly via changing the metallurgical characteristics of the grain boundary [25]. At present, systemic works regarding the effect of micro-alloying on the microstructure and mechanical behaviours of Co-Al-W based alloys are still seldom.…”
