The yield stress and work hardening behaviour of precipitation hardening alloys is directly related to the nature of the interaction between mobile dislocations and precipitates. In commercial systems such as aluminium alloys, the understanding of this problem is complicated by the overlap between v

The influence of precipitation hardening on the characteristics of serrated yielding in an Al-IMg-Si alloy has been investigated. The critical strain at the onset of serrated yielding was increased by ageing and for ageing times longer than 6 hr at 180°C serrated yielding was not observed. The strai

The effect of iron on the precipitation of a technical Al-Mg-Si alloy was studied by macroand microhardness, Y-modulus and SANS with D K D and was coinpared with a pure alloy. The iron phases of the technical alloy were preferentially considered by the SANS. I n addition the daniping by the elastoma
