Deformation and strength behavior of two nickel-base turbine disk alloys at 650 °c
The strength and deformation behavior of two nickel-base turbine disk alloys at 650 ° C was analyzed. The compression tests consisted of a combination of antiphase boundary (APB)-connected dislocation pairs and partials creating superlattice intrinsic stacking faults (SISF). Experimental results showed an increase in the fault density for unimodal alloys with a decrease in both particle size and strain rate
