Understanding the Solidification and Refinement of Steels

Abstract

Understanding the Solidification and Refinement of SteelsAbstract: This purpose of this project is to continue to develop our understanding of solidification basedgrain refinement in steels and the solidification of steels in general. This project will focus onrare earth and titanium based grain refining materials. Cooling curve thermal analysis will beconducted to determine how the pres"ence of rare earth or titanium containing inclusions changethe solidification path of 1030, 4130, and HY80 steels. This analysis wi"ll provide a betterbackground on how these alloys solidify and how inclusions act as nuclei for steels. A series ofexperiments will also be conducted on a rare earth element based grain refiner. The developmentof such a grain refiner will enable the researcher to choose specific inclusion compositions tohelp determine which are effective nuclei. This work will enable the creation of stronger andmore ductile steels without significant alloying changes to existing steel compositions.The project will be conducted at Sa"ginaw Valley State University, which is located nearSaginaw, MI. Both undergraduate and graduate students will work on the project.
