Abstract

Effect of multi-step ageing of Al-Li system influences the decomposition of the solid solution at the first step on morphology of precipitates at the following steps. It results in a decrease of size and increase in the volume fraction of strengthening phases. The uniform distribution of precipitates also eliminates formation of non-desirable phases or provides a discreteness to stable phase precipitates along the grain boundary and a decrease of the width of precipitates free zone along the boundary. Usage of multi-step ageing regimes allows to increases fracture toughness, corrosion resistance and thermal stability in comparison with the one-step ageing for Al-Li system.
