Herein,　a　novel　method　is　proposed　to　prepare　the　multimaterial　composite　component　for　aerospace　applications　using　the　current　sintering.　Two　representative　high-temperature　structural　materials,　the　new　potential　intermetallic　NiAl　and　the　widely　used　Ni-based　superalloy　K4202,　have　been　employed　to　achieve　the　target.　As　shown　by　the　results,　a　clean　interface　with　almost　no　defects　is　successfully　obtained　in　NiAl/K4202　alloy.　Nevertheless,　the　existence　of　a　continuous　Cr(Mo)　phase　along　the　region　leads　to　an　insufficient　bonding　ability.　To　optimize　the　interfacial　microstructure,　a　Ni　foil　is　employed　as　the　interlayer.　The　results　indicate　that　the　interlayer　can　hinder　the　intense　diffusion　of　elements　and　prevent　the　abnormal　growth　of　Cr(Mo)　phases,　which　result　in　a　considerable　improvement　of　interfacial　properties.　©　2023　Wiley-VCH　GmbH.
