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.
