Then, the microstructures produced and corrosion behaviour after heat treatment was studied in detail. As-cast AZ91D was recrystallize by solution treatment at 415°C and then aged at 175°C for various period of time. The corrosion resistance of all the different microstructures was studied in NaCl solution through weight loss measurement in immersion testing. The β phase was found to have a significant influence on the corrosion behaviour. In solution treatment, β phase dissolution decreased the cathode area leading to accelerated corrosion rate. After aging treatment, fine β phase precipitates between grain and microstructure recrystallize causing an increase in the corrosion resistances. 2014-04-25T01:58:45Z 2014-04-25T01:58:45Z 2013 Article Advanced Materials Research, vol. 685, 2013, pages 102-106 978-303785676-5 1022-6680 http://www.scientific.net/AMR.685.102 http://dspace.unimap.edu.my:80/dspace/handle/123456789/34041 en Trans Tech Publications |
