The calculated Birch-Murnaghan EOS for each composition demonstrate an increase in K 0 with rising W content and are in good agreement with previous computational studies. Furthermore, V 0 decreases as Mo is substituted by W, corresponding to the increase in valence electron density, hardness, and K 0 . Experimental determination of trends in K 0 within Mo 2-x W x BC solid solutions can inform future computational and experimental design endeavors in the search for environmentally sustainable materials with superb mechanical response.
