Impact toughness of ternary Al–Zn–Mg alloys in as cast and homogenized condition measured in the temperature range 263–673 K

[摘要] Impact toughness of six Al–Zn–Mg ternary alloys are compared with two Al–Zn binary alloys and one CP aluminium metal at eight different temperatures of 263, 268, 273, 300, 373, 473, 573 and 673 K. The effects of alloying and temperature on toughness have been compared and analysed. The influence of alloying is more pronounced than that of temperature in reducing the toughness.
