1. Introduce
– A newer vane material that is replacing the older alloy, X-45, in some designs due to its higher creep strength
– The ECY-768 alloy is a modified Mar-M 509 with improved castability
2. Property
– High temperature strength, good creep strength
| Element | Impact |
|---|---|
| Co | Provides high temperature creep strength, abrasion resistance |
| Cr | Provides corrosion resistance, strength |
| W | Provides high temperature hardness, abrasion resistance |
| Ta | Provides Strength |
