    摘要: The present invention relates to a method of producing a high damage tolerant aluminium alloy rolled product a high toughness and an improved fatigue crack growth resistance, including the steps of: a.) casting an ingot having a composition selected from the group comprising AA2000, AA5000, AA6000, and AA7000-series alloys; b.) homogenising and/or pre-heating the ingot after casting; c.) hot rolling the ingot into a hot rolled product and optionally cold rolling the hot rolled product into a cold rolled product, wherein the hot rolled product leaves the hot rolling mill at an hot-mill exit temperature (TExit) and cooling the hot rolled product from the TExit to 150° C. or lower with a controlled cooling cycle with a cooling rate falling within the range defined by: T(t)=50−(50−TExit)eαt and wherein T(t) is the temperature (° C.) as function in time (hrs), t is the time (hours) and α is in the range of −0.09±0.05 (hrs−1).
