Understanding Solidification Based Grain Refinement in Steels

Abstract

The overall goals for this project are to elucidate the grain refinement mechanism in cast steels, develop a master grain refining alloy, and determine how heat treatment affects grain refined structures. Specific objectives: 1) Determine the cause of intermittent grain refinement in 1010 and 1030 alloys with rare earth additions. 2) Create a master alloy based on rare earth oxides. 3) Extend steel solidification knowledge by understanding how nucleation events occur. 4) Examine how industrial heat treatments affect the structure and properties of grain refined steels. 5) Determine if heat treatments can be modified to improve properties for grain refined steels.
