Abstract

Phase transformations in Cu-12.4% Al and Cu-14.4% Zn-8.4% Al alloys were examined by DTA. The influence of the rate of temperature change on the sequence of phase transformations was studied. It was found that the rates of heating and cooling were the major factors determining the transformations which take place in these alloys.

Zusammenfassung

Phasenübergänge in den Legierungen Cu - 12,4% Al und Cu - 14,4% Zn - 8.4% Al wurden thermoanalytisch untersucht. Der Einfluß der Geschwindigkeit der Temperaturänderung auf die Reihenfolge der Phasenübergänge wurde untersucht. Aufheiz- und Abkühlgeschwindigkeit sind die wichtigsten Faktoren, von denen die Phasen übergänge in diesen Legierungen abhängen.

Резюме

Методом ДТА исследов аны фазовые превраще ния сплавов медь - 12,4% алюмин ия и медь - 14,4% цинка - 8,4% алюмин ия. Изучено влияние ск орости изменения температу ры на последовательность фазовых превращений. Найдено, что скорости нагрева и ох лаждения являются главными фа кторами, определяющи е происходящие в этих с плавах превращения.
