  6. A Study of Reduced Chromium Content in A Nickel-Base Superalloy via Element Substitution and Rapid Solidification Processing

    Powers, William OwenUniversity of Illinois at Urbana-Champaign2014

    A study of reduced chromium content in a nickel-base superalloy via element substitution and rapid solidification processing was performed. The base alloy studied was a commercial nickel-based superalloy, 713LC, which was developed by the INCO family of companies. The two elements used as partial …
