Two step–ageing of 7xxx series alloys with an intermediate warm-forming step

Two step–ageing of 7xxx series alloys with an intermediate warm-forming step

Two-step ageing of 7xxx series alloys can reduce ageing time while obtaining similar mechanical properties as a longer isothermal heat treatment. In this paper, an intermediate deep-drawing step at 120–160 °C is introduced to produce elongated cup–shaped parts with near-T6 strength. A Cu-containing...
