Abstract
High-Temperature Laser Scanning Confocal Microscopy (HT-LSCM) is an in situ technique that can be used for direct observation of the microstructure during melting, solidification, and solid-state cooling. Therefore, this tool is a powerful method that can be used to understand how cooling conditions affect the solidification structure and degree of alloy segregation in steel castings. In the current study, specimen shape and size were optimized for this technique using an ultra-low-carbon steel. HT-LSCM was then utilized to observe the melting and solidification phenomena as a function of cooling rate for the ultra-low-carbon steel as well as a high-alloy austenitic manganese and aluminum steel. The growth kinetics and evolution of the solid–liquid interface during solidification were derived from time-lapse videos. The resulting solidification microstructure was determined utilizing scanning electron microscopy.
期刊介绍：
The International Journal of Metalcasting is dedicated to leading the transfer of research and technology for the global metalcasting industry. The quarterly publication keeps the latest developments in metalcasting research and technology in front of the scientific leaders in our global industry throughout the year. All papers published in the the journal are approved after a rigorous peer review process. The editorial peer review board represents three international metalcasting groups: academia (metalcasting professors), science and research (personnel from national labs, research and scientific institutions), and industry (leading technical personnel from metalcasting facilities).
