ZrO2 strengthened NiAl/Cr(Mo,Hf) composite fabricated by powder metallurgy

Optimization of the Microstructure and Mechanical Properties of a Laves Phase-Strengthened Hypoeutectic NiAl/Cr(Mo,W) Alloy by Suction Casting

“…In order to improve mechanical properties of NiAl, lots of methods have been applied and so many NiAl based materials have been designed and fabricated [15][16][17][18]. Yang et al [19] fabricated the NiAl/Cr(Mo) eutectic alloy and investigated its deformation mechanism which indicates the appropriate Cr(Mo) and NiAl lamellar structure was beneficial to mechanical properties.…”

TEM investigation on ceramic strengthening NiAl-based composite prepared by thermal explosion and hot extrusion

“…2(b). The inset selected area electron diffraction (SAED) pattern gives that TiC particle has an orientation relationship with NiAl matrix of [100] TiC //[100] NiAl and (020) TiC //(0-11) NiAl , which was reported in the former research [12]. However, further observation on NiAl and TiC interface finds that an amorphous transition layer with several nanometers exists between NiAl and TiC, as shown in Figure. 2(c).…”

“…Therefore, to overcome the shortcomings of the NiAl, many techniques [8][9][10][11] have been adopted, among which fabricating NiAl based composites by adding stiffness particles is a convenient way to obtain improvement in high temperature properties. For example, boride strengthening NiAl based composite, oxide strengthening NiAl based composite and nitride strengthening NiAl based composite have been investigated extensively to incorporate the ceramics particles into the NiAl matrix [12,13]. Generally, NiAl based composite strengthened by ceramic particles can be obtained by reaction synthesis, which is an easy, quick and economic method [14][15][16].…”

Incorporation and evolution of ZrO2 nano-particles in Pt-modified aluminide coating for high temperature applications

“…at.%) composite alloy instead of reacting with Al [29]. This may suggest that large ZrO2 particles may have different effects on the reaction between Al and ZrO2.…”
