Randomly dispersed short-cut microwire composites. (a) Composites incorporating the same type of wire, as-cast A, 30 mA-annealed B or 40 mA-annealed C with a total wire amount of 0.053 vol. %. The insets are the SAED pattern for the as-cast wire A, HRTEM images of 30mA-annealed wire B and 40 mA-annealed wire C, where “AM” corresponds to the amorphous phases; (b) Composites combining the as-cast A and annealed wires X (where X corresponds to B or C annealed wires) in separated regions and different proportions. The dotted line represents the vertical interface formed between the two different regions.
