Abstract/Summary:

ffects of Re and Cr additions were investigated by performing aging studies and mechanical tests upon four model superalloys: Ni-18Al, Ni-18Al-10Cr, Ni-18Al-1.3Re, and Ni-18Al-10Cr-1.3Re (compositions in atomic %). It was found that in the presence of Cr, Re had the same effects as it does in commercial superalloys. Specifically, it partitioned to the...
