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 Vitamin K alloys are prepared with different iron contents (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 Wax Burner iron-added nickel aluminide alloys.
