| Description |
This in vestigation is aimed to understand crack initiation resistance and mechanism of cracking in a high entropy alloy, Al23Co15Cr23Cu8Fe15Ni15 (at%). The fracture toughness of the alloy consisting of primarily Fe–Cr rich disordered and Al–Ni richordered BCC phases is found to be 5.4 +/- 0.2 MPa m1/2. Lower magnitude of fracture toughness has been at tributed to nanosized microstructural constituents, in which cracking is governed by formation of shear bands, cleavage facets and herringbone type features.
