Figure 4. Dilatant shear bands observed in HPDC samples produced with filling velocities of 2.2 ms1 (top row), 3.6 ms-1 (middle row) and 4.2 ms-1 (bottom row). Typical macrostructure of etched samples from the centre of the gage section are shown (left) and corresponding EDX maps highlighting eutectic fraction are shown (right).
