Determination of phase equilibria in the Co-rich Co–Al–W ternary system with a diffusion-couple technique
Abstract Phase equilibria in the Co-rich Co–Al–W ternary system were determined with a unique diffusion-couple technique in which Co–27Al and Co–15W binary alloys (at. %) were first coupled for
The effects of alloying elements (Ta, Hf) on the thermodynamic stability of γ′-Co3(Al,W) phase
Abstract This paper investigated the effects of alloying elements (Ta, Hf) on the thermodynamic stability of γ′-Co3(Al,W) phase with an L12 structure at 900 °C, based on microstructure observations
Phase equilibria in the Co-rich Co-Al-W-Ti quaternary system
Abstract We determined phase equilibria in the Co-rich Co-Al-W-Ti quaternary system at a temperature range between 900 °C and 1200 °C with a close attention to the thermodynamic stability of the
The Stability of γ ’-Co3(Al,W) Phase in Co-Al-W Ternary System
The thermodynamic stability ’- Co3(Al,W) phase (L12) in the Co-Al-W ternary system at 900 °C was investigated through microstructure and EPMA analysis on a heat-treated bulk alloy. To promote
Magnetic property and structural changes in TbFeCo by heat treatment below crystallization temperature
In magneto-optical recording using sputtered TbFeCo, it was observed that writing sensitivity appreciably increases after writing/erasing repetitions. To clarify this phenomena, magnetic properties
Alloying Effects on the Stability of γ/γ′ Microstructure in Co-Al-W Base Alloys
The aim of this study is two-fold: first we reexamine the thermodynamic stability of γ’-Co 3 (Al,W) phase in the Co-Al-W ternary system. Secondly, we investigate the effect of a fourth alloying
