Critical assessment of copper–gold–silver ternary system

摘要: AbstractA critical assessment has been made of the phase equilibria Ag–Au–Cu system. An introductory section summarises main features ternary equilibria. Phase separation occurs in Ag–Cu system and ordering reactions Au–Cu In disordered Ag-rich Cu-rich phases begins at 800°C, whereas associated with Au-Cu occur temperatures below 400°C. Detailed consideration is given to liquidus, solidus, solvus surfaces low temperature which ordered play a major role. interpretation current data summarised proposed reaction scheme for
