摘要

Characteristic features of heat treatment of aluminium-lithium alloys are connected mainlyrnwith a presence of the general hardening phase δ' (Al3Li) both independently and as arnshell on θ', θ", Al3Zr and Al3Sc phases of composite two-phase particles. Influence of thernmulti-step artificial ageing of Al-Li-Cu, Al-Li-Mg-Cu and Al-Li-Mg alloys on phaserncomposition, precipitates morphology (particle size and distance between them), presence and width of precipitated free zones along boundaries is studied. Usage of multi-step ageing regimes allows to increase a fracture toughness, corrosion resistance and thermal stability in comparison with one-step ageing for Al-Li alloys.
