Unalloyed nickel aluminide has important applications but lacks ductility at room temperature.In this study, iron-added nickel aluminide alloys exhibit plasticity enhancement.The nickel aluminide alloys are prepared with different iron contents Fuse Fast Blow (0, 0.25, and 1 at%) to study their plasticity.
The indentation-induced deformed areas are mapped by the synchrotron X-ray diffraction to compare their plastic zones.A complimentary tight binding calculation and generalized embedded atom method demonstrate how the Fe-addition enhances the plasticity of the Travel Bottles iron-added nickel aluminide alloys.
