B-1900 Ni Superalloy
Material Description
B-1900 was a nickel based superalloy developed in the 1960's[1]. Its primary use, like most superalloys, is in high temperature applications like turbine airfoils[2]. The nominal specifications are captured in the table below [3].
| Element | Ni | C | Cr | Co | Mo | Fe | Al | B | Ti | Ta | W | Zr | Hf |
|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
| Percentage | 64 | 0.1 | 8 | 10 | 6 | - | 6 | 0.015 | 1 | 4 | - | 0.10 | 1.5(for B-1900 + Hf only) |
Mechanical Properties
The mechanical properties of this alloy are given for tension and compression tests considering temperature and strain rate.
Tensile Properties
Stress strain behavior in tension and at various temperatures. Strain rate = 8.33e-5 s-1[4].
Stress strain behavior in tension and at various temperatures. Strain rate = 100e-6 s-1[5].
Stress strain behavior in tension and at various temperatures. Strain rate = 100e-6 s-1[5].
Fatigue Properties
Strain life behavior at various temperatures[4].
Strain life behavior at two temperatures and with three methods: HROP - Bithermal high rate out-of-phase CCOP - Bithermal compressive creep out-of-phase TMOP - Thermo mechanical out-of-phase[6].
