- n.b. means that the corresponding Value was not determined.
- the NiAl-Ta-Cr alloy Compared to conventional super alloys, the NiAl-Ta-Cr alloy has the advantage that they are also above 1050 ° C to 1150 ° C has sufficient strength. It there is no sudden drop in strength in this alloy, due to the dissolution of the solidified phase is.
- Table 5 shows a comparison of the values of K IC values of various ceramics known from industry data and of the processed powder-metallurgical processed NiAl-Ta-Cr alloy.
- the toughness of the intermetallic NiAl base alloy is significantly better than the measured data for binary NiAl and SiC.
- the alloy has a good oxidation resistance of the order of 5 ⁇ 10 -14 g 2 cm -4 s, which is therefore equal to or better than the oxidation resistance of binary NiAl.
- no protective layers for example made of ceramic material, are necessary at high temperatures. This eliminates the problem of the connection between ceramic and metallic components.
- Adequate thermal shock resistance is given. At The alloy has 500 temperature cycles without 1350 ° C damage to the material.
