INFLUENCE OF ALLOYING OF COPPER ON SEIZING IN CAPABILITY TEMPERATURES RANGE 23-450C.
Abstract
To study more fully the influence of alloying on seizing capability and its connection with the mechanical properties of alloys, a study was made of a large number of copper alloys in the region of solid solutions. Seizing capability was determined according to joint plastic deformation of pairwise formed sheet samples by symmetrically slanted punches by the method described earlier. The deformation of seizing found thus (minimum depths of penetration of punches at which durable bonding of samples occurred) were, for determination of specific pressures of seizing, plotted on curves representing the dependence of magnitudes of deformation on pressures applied during deformation of the same samples by flat narrow punches. The results of the investigation confirm that, for alloys of copper, the dependence of seizing capability with the dissolution of alloying components on the change of crystal lattice parameter and that of seizing capability on temperature are important indices of antifriction properties of alloys. Probably, analogous dependences can also serve as leading principles for the evaluation and creation of antifriction alloys on the basis of other metals.
