Аннотация: Ni-AlNi metallic-intermetallic laminate (MIL) composites have been fabricated in open atmosphere using commercial purity Ni and Al foils with 250 μm initial thickness. Sintering process has performed at 700ºC under 2 MPa pressure for 5 hrs. Composite consisting of alternating layers of metallic Ni and the intermetallic AlNi have been fabricated by reactive foil sintering in open atmosphere furnace. The aluminum foil was almost consumed by forming a nickel aluminide intermetallic compound. Thus, the final microstructure consists of alternating layers of intermetallic compound and unreacted Ni metal. Microstructure and phase characterization were performed by scanning electron microscopy (SEM), energy dispersive spectroscopy (EDS) and x-ray diffractometry (XRD). Hardness values of test samples have also measured as 800 HV by vickers indentation method.
