Microstructure of Layered Porous TiAl Composite Sheet Synthesized by Reacted Sintering
In this paper, pure Ti foil, pure Al powder and pure Nb powder are used as raw materials Firstly, AlNb composite foil was prepared by powder metallurgy process, and then layered porous TiAl alloy sheet is prepared by foil metallurgy The results show that after vacuum hot pressing, there is no new...

| description | In this paper, pure Ti foil, pure Al powder and pure Nb powder are used as raw materials Firstly, AlNb composite foil was prepared by powder metallurgy process, and then layered porous TiAl alloy sheet is prepared by foil metallurgy The results show that after vacuum hot pressing, there is no new phase in the Ti/AlNb composite sheet, and the combination of Ti foil and AlNb composite foil is mechanically combined, and the thickness of the sheet is uniform The thin plate after step heat treatment is composed of six phase layers of Al3Nb, TiAl3, TiAl2, TiAl, AlNb2 and Ti3Al, wherein the TiAl phase layer has a thickness of about 100 μm, the Ti3Al phase layer has a thickness of about 12 μm, and the (Ti, Nb) Al3 phase layer thickness It is about 80 μm and the thickness of the TiAl2 phase layer is about 2 μm AlNb2 is distributed in the (Ti, Nb)Al3 phase layer, and irregularly distributed pores are formed in the (Ti, Nb)Al3 phase layer |
