INFLUENCE OF SILVER ADDITIONS ON THE STRUCTURE AND PHASE-TRANSFORMATION OF THE CU-13 WT-PERCENT AL-ALLOY

The influence of silver additions on the structure and phase transform ation of the Cu-13 wt% Al alloy was studied by differential thermal an alysis, X-ray diffraction, scanning electron microscopy and energy dis persive analysis of X-rays. The results indicate that the presence of silver modifies the phase-stability field, the transition temperature and the structure of the alloy. These effects are more pronounced for silver concentrations up to 8 wt%.
