Fig. 6. SEM image SE mode of the Cu 42.5 Zr 45 Co 12.5 ingot after fracture. A crack is depicted, which propagates in the interdendritic region indicating its brittleness. The vertical arrow marks where a branch of the crack is stopped by the softer B2 dendrites. The horizontal arrows show where martensite laths form in the dendrite in the vicinity of the crack.
