Title

QUALITY CONTROL OF PRECIPITATION HARDENED ALUMINIUM ALLOY PARTS VIA EDDY-CURRENT NONDESTRUCTIVE EVALUATION

Pages

  83-87

Abstract

 Precipitation hardening is the most common method in the strengthening of aluminium alloys. This method relies on the decrease of solid solubility with temperature reduction to produce fine precipitations which impede the movement of dislocations. The quality control of aluminium alloy specimens is an important concern of engineers. Among different methods, non-destructive techniques are the fastest, cheapest and able to be used for all of parts in a production line. To assess the ability of EDDY CURRENT as a non-destructive method in the evaluation of PRECIPITATION HARDENING of aluminium alloys, 7075 ALUMINIUM ALLOY specimens were solution treated at 480° C for 1 hr. and followed by water quenching. Afterwards, the specimens were aged at different temperatures of 200, 170, 140, 110 and 80°C for 8 hr. EDDY CURRENT measurements was conducted on the aged specimens. Hardness measurement and tensile test were employed to investigate the mechanical properties. It was demonstrated that EDDY CURRENT is effectively able to separate the specimens with different aging degree due to the change of electrical conductivity during aging process.
