In recent years, discontinuously reinforced aluminum matrix composites have been identified as candidates for high temperature applications, where understanding of creep behavior of the material is important. In this study the authors report an anomalous creep behavior of an XD Al-TiB[sub 2] composite observed at higher temperatures. These anomalies include the presence of a sigmoidal primary creep stage, a temperature-dependent primary strain, and similar steady state creep strengths at 623 and 673 K. These observations differ from the normal creep behavior of Al-TiB[sub 2] composite produced by the conventional powder metallurgy route.
