Aging-induced changes in the austenite peak (A P ) temperature of Au 7 Cu 5 Al 4 shape-memory alloy are investigated. Whereas heat treating the parent phase at temperatures >140 Β°C or aging the martensite for long times at room temperature both stabilized the A P to $80 Β°C, low-temperature excursion
