Monotonic properties of powder metallurgy materials such as tensile, creep, and stress rupture are governed by the chemical composition and grain structure.
TABLE 12.2 Composition of Powder Metallurgy Material for Brazing
The finer equiaxed grain structure of powder metallurgy material tends to lower the creep properties when compared with large-grained high-strength super- alloys.
Some examples of brazing with powder metallurgy materials indicate the effectiveness of the procedure.
Figure 12.15 shows the com- ponent after the repair procedure, with darker areas representing the area where the powder metallurgy material is applied.
