摘要：

The mechanical properties of some rapid-quenched, partly-amorphous (as-prepared) PdSiSb alloys have been studied. These alloys showed tensile strengths (fracture force/fracture surface area) of 58-232 kg/mm2, depending on their amorphous fraction (0-6%). The alloy's high strengths are due to an unusual microstructure, which consists of fine ( < 1 μm) dendrites of a ductile, supersaturated solution of Si and Sb in f.c.c. Pd, embedded in an amorphous matrix. The role of the glassy matrix in the fracture process is discussed. © 1979.
