Abstract Scope |
Multi-principal element alloys of the WMoFeNi system appear to exhibit self-sharpening behavior, which is primarily facilitated by the dispersion of μ phase precipitates throughout a comparatively soft FCC matrix. A thorough characterization of the phase transformations occurring for WMoFeNi alloys can thus be leveraged to regulate the composition, morphology, and distribution of the μ phase and optimize the resultant mechanical properties. Herein, the phase transformations for W0.125Mo0.375FeNi alloy are identified using differential scanning calorimetry (DSC). The microstructural characterization of bulk as-cast and cold-worked specimens via scanning electron microscopy and X-ray diffraction is provided to correlate the DSC data with underlying changes in the morphology and distribution of the μ phase. Overall, the present work demonstrates the utility of thermal analysis in elucidating the mechanisms underlying μ phase precipitation and dissolution in WMoFeNi, an understanding of which is vital to the potential applications of these alloys. |
