Abstract
A copper alloy containing amorphous B2O3 dispersed particles is made by internal oxidation of a dilute Cu-B solid-solution alloy. Although the B2O3 particles behave as plastically non-deformable particles at room temperature, these become liquid particles in the solid Cu matrix at high temperatures. Cu single crystals containing the B2O3 particles are tensile tested at high temperatures. The shape change of the liquid particles due to the plastic deformation of the Cu matrix is observed with electron imcroscopy. The occurrence of relaxation by the diffusion of the Cu atoms along the Cu/B2O3 interface affects the shape change. The kinetics of the diffusional relaxation is discussed on the basis of the results of observations of the particle shape.
