Abstract
The influence of solid solution treatment temperature (SSTT), stretching and two- and three-stage ageing regimes on the tensile properties, IGC, K e (K e0 ) and FCPR of sheets from 6013 alloy in comparison with properties of 6013T6 and 6056T78 alloys sheets has been investigated. The recommended regimes including stretching and two- and three-stage ageing allow to eliminate IGC and to increase strength properties of sheets from 6013 alloy, providing for the higher values of the strength, fracture toughness and the decrease of FCPR in comparison with 6056T78. The precipitates phase composition in body of grains and on the GB is the same - Q'(β')-phases. Their sizes and the width of PFZ are lower than after the standard overageing regime (T78).
