The electro-discharge machining (EDM) characteristics of a NiAlFe ternary shape memory alloy (SMA) have been investigated in this study. Experimental results reveal that the material removal rates (MRRs) of Ni 60Al 24.5Fe 15.5 and Ti 35.5Ni 49.5Zr 15 alloys in the EDM process exhibit a reverse relat...
