摘要
Al-matrix particulate composites are melted and mixed with immiscible metals to form their small droplets in liquid aluminum. It is shown that, in the Al-Si/SiC/Bi system, the Bi droplets are stabilized by the SiC particles in the liquid Al matrix. Upon solidification, homogeneous distribution of solidified Bi droplets is obtained in the Al matrix at the bottom part of the ingot. Thus, a new class of engineering materials (particle-stabilized monotectic alloys) is obtained.
