Notes:
The tensile strength, proof strength, hardness and electrical conductivity of Al alloy 7010under different temper and ageing conditions were investigated with the aim to correlate strengthwith hardness and electrical conductivity so that the strength of the alloy can be determined nondestructively.Following the solutionising treatment, continuous age hardening was performed on aseries of test coupons, taken from a large plate, to produce a wide range of precipitation hardeningconditions, which gave rise to progressive variations of strength, hardness and conductivity. Therelationship between strength and hardness was found to be reasonably linear, whereas therelationship between hardness and strength with electrical conductivity was non-linear. The ageingconditions and therefore the mechanical properties of the components can be predicted moreaccurately by the simultaneous combination of hardness and conductivity values
