Phase transformation in Mo - Ru alloy induced by laser heating at high pressures
Phase transformations in the Mo-Ru alloy system were investigated at high pressures and high temperatures in a laser-heated diamond anvil cell. The room temperature compression of Mo-20 at.% Ru alloy to 67 GPa revealed that the bcc phase is stable to the highest pressure. Laser heating at high press...

Summary: | Phase transformations in the Mo-Ru alloy system were investigated at high pressures and high temperatures in a laser-heated diamond anvil cell. The room temperature compression of Mo-20 at.% Ru alloy to 67 GPa revealed that the bcc phase is stable to the highest pressure. Laser heating at high pressures performed without an insulating medium resulted in the formation of Mo sub 2 C phase. However, controlled laser heating to 2200K at 20 GPa with KCl insulating medium showed that the bcc phase transforms into a mixture of bcc and sigma ( sigma ) phases. The present phase-stability data are discussed within the context of the rigid-band model and electron transfer under high pressures in transition metal systems. |
