Aluminium, copper, silver and nickel-base dispersion-strengthened materials were studied by many researchers. There are, however, few reports on dispersion strengthened iron. In the present work, the hardness and the thermal expansion of dispersion-strengthened iron and copper were studied. Pure powders of iron or copper were used as base metal and fine powders of alumina, magnesia and silica as dispersed particles. These powders were mixed and pressed at room temperature, and sintered at 1300°C and 10000°C for iron and copper, respectively. The results obtained were as follows. (1) In both iron and copper, alumina proved to be the most effective and silica to be the least as dispersion-strengthening particles. (2) The less the expansion coefficient, the stronger the effect of dispersion-strengthening. (3) Cold-worked iron or copper containing silica softens at recrystallization temperature, while that containing alumina softens little, even in austenite temperature range.
