Synthesis of intermetallic Ni3Al Alloy: properties and high temperature oxidation behavior

Two different methods were utilized to synthesize intermetallic nickel aluminide alloy. The first method was combination of powder metallurgy and reaction synthesis (IMC-RS) and the second method was plasma melting to form homogenous plasma melted samples (IMC-PM). XRD patterns for both samples show...
