抄録

RuAl is one of the potentially useful intermetallics with a high melting temperature(2333K) as a structural material. Ru_100-xAlx(x=45, 47.5, 50, 52.5, 55at%) powders were prepared by mechanical alloying (MA). The MA powders were subsequently consolidated by Plasma Activated Sintering process(PAS) at 1673-1773K for 10 minutes under 50MPa pressure. Each compact had sub-micron structure, which were consist of Ru and RuAl for 45, 47.5 and 50 at%Al compacts, RuAl and RuAl2 for 52.5 and 55 at%Al compacts. Compressive tests were carried out for Ru-Al compacts at room temperature. Some of them below 50 at%Al exhibited compressive yield stress of 2.0-2.8 GPa and compressive yield strain of more than 25%.
