Phase Equilibria in System Pd-Au-Sn and Pd-Cu-Sn at 800°C and 500°C

摘要

Alloys of Pd-Au-Sn and Pd-Cu-Sn systems were investigated using metallography, electron microprobe,X-ray diffraction and DTA. Partial isothermal sections were plots at 800°C and 500°C. Ternary t-phase havingtetragonal structure has been established in each systems. The region of existence of phases in equilibrium withthe solid solution based on palladium.
