Original Abstract

The influence of solution heat treatment on corroison behaviour and mechanical properties of AZ61 magnesium alloy prepared by squeeze casting was evaluated. Experimental material was subjected to solution heat treatment at 380 C for various periods of time with subsequent water quenching. Metallographic analysis and tensile test were performed for assessment of optimum conditions of heat treatment. A temperature of 380 C and annealing time of 6 hours at the temperature were found to be optimal. Corrosion behaviour of both conditions, as cast (F) and solution heat treated (T4) was evaluated through neutral salt spray test and electrochemical spectroscopy method. Corroison rate was established on the basis of mass losses, teh corroded surfaces were analyzed using SEM.
