Microstructural Evolutions and Strengthening Mechanism according to the Aging Temperatures of a High Si Cast Aluminum Alloy
Won-Sang Shin, Yoon-Jun Kim
Korean J. Met. Mater. 2023;61(7):524-533.   Published online 2023 Jun 21
DOI: https://doi.org/10.3365/KJMM.2023.61.7.524

Abstract
A356 cast aluminum alloy contains 7 at.% Si and 0.3 at.% Mg, producing an approximately 50% eutectic microstructure. This high Si content and various casting conditions play a significant role in strengthening A356 alloy, by controlling the eutectic morphology and precipitates of other intermetallic compounds. Understanding how Si-related precipitates and..... More

Korean J. Met. Mater. 2020;58(8):540-549.   Published online 2020 Jul 27
DOI: https://doi.org/10.3365/KJMM.2020.58.8.540

Abstract
The effect of aging heat treatment conditions on the mechanical properties and microstructure of the base and weld metal of Alloy 282 superalloy was investigated. The aging heat treatment conditions employed in this study were as follows: two-steps (1010 °C for 2 hours plus 788 °C for 8 hours) and..... More
