Abstract
A method of making metal/refractory composites includes bubbling a reactive gas through a melt to form a foam including refractory particles. In continuous mode, the foam is separated from the melt and the melt replenished. Composites of lightweight metals reinforced with discontinuous refractory ceramic particles can be efficiently and economically produced.
