Thebulk materials consolidated from 0 h and 4 h mechanically milled powders were characterised byVickers hardness tests and density measurements. Thermal stability of the consolidated bulkmaterials was evaluated by isothermal heat treatments at 673K. The as-consolidated bulk materialfrom the 0 h milled (i.e. unmilled) powder showed nearly full density. However, full density was notobtained with the 4 h milled powder even after eight passes. The HV values for the as-consolidatedmaterials fabricated from the 0 h and 4 h milled powders after four passes and from the 4 h milledpowder after eight passes were 57, 121 and 136, respectively. Softening was observed in the bulkmaterial consolidated from the 0 h milled powder during the isothermal heat treatment. However, thehardness of the bulk materials consolidated from the 4 h milled powders after four and eight passesincreased to maximum values of 137 and 141 after heat treatment for 28 h and 8 h at 673K,respectively. The maximum hardness was maintained for up to 100 h at 673K in both materials. Thehardening and thermal stability in the bulk materials from the milled powders are attributable todispersion strengthening of Al4C3 particles formed by solid-state reaction during the isothermal heattreatment.
