Jen. Dato' Prof. Dr. Shaiful Rizam, Shamsudin mazlee@unimap.edu.my Endothermic peaks Solidification structures Superheating A357 Alloy Link to publisher's homepage at http://myais.fsktm.um.edu.my/ The microstructure of superheated as-cast A357 alloy has been analysed to study the solidification structures of α-Al dendrites, eutectic Si particles and intermetallic compounds at different sections of the specimen. The primary dendritic arms are broken to globular and spherical shaped of α-Al dendrites due to the thermal effect of superheating thermal treatment. Differential scanning calorimetry showed faster formation of endothermic peaks of superheated as-cast A357 alloy relatively also believed to be attributed by superheating thermal treatment. The solidification sequence of superheated A357 alloy was same as Sr modified Al7Si-Mg alloy [4] except for the reaction involving Al5FeSi intermetallic compound which started with Liq. → Al dendrites followed by Liq. → Al + Si and lastly Liq. → Al + Si + Mg2Si + Al8FeMg3Si6. 2010-08-20T07:40:25Z 2010-08-20T07:40:25Z 2009 Article International Journal of Mechanical and Materials Engineering, vol.4(2), 2009, pages 181-185 1823-0334 http://myais.fsktm.um.edu.my/10304/1/MICROSTRUCTURAL_STUDY_AND_DIFFERENTIAL_SCANNING_ALORIMETRY_ANALYSIS_AT_ELEVATED_TEMPERATURES_OF_UPER.pdf http://hdl.handle.net/123456789/8901 en University of Malaya
