XRD and DSC traces obtained from as-cast alloys with , 0.25, and 0.5, respectively.
Room temperature compressive engineering stress-strain curves obtained from the ( and 0.5) samples.
Secondary electron SEM images taken from the deformed (before failure) and failed samples ( and 0.5): (a) outer surface, [(b) and (c)] fracture surface morphologies of sample; [(d) and (e)] lateral surface morphologies of deformed sample; and (f) fracture surface morphology of failed sample for the sample, respectively. The insets in (e) and (f) show a highly magnified image for the dashed circle region in (e) and the outer shape of the failed sample, respectively.
High-resolution TEM images and corresponding FFT patterns of the as-cast rod samples with and 0.5, respectively.
Compressive mechanical properties, density, and elastic constants for the as-cast alloys with , 0.25, and 0.5, yield stress , yield strain , ultimate compressive stress , plastic strain , density , Poisson’s ratio , Young’s modulus , shear modulus , and bulk modulus .
