Microstructural characteristics and mechanical properties of extruded TZA822 alloys.
| State | Microstructure | Mechanical Properties | |||||||
|---|---|---|---|---|---|---|---|---|---|
| FDRX (%) | dDRX (μm) | Texture Intensity | TYS (MPa) | UTS (MPa) | EL (%) | CYS (MPa) | YR | n | |
| Without T4 | 86.2 ± 3.1 | 2.96 ± 0.34 | 3.1 | 186 ± 3 | 231 ± 4 | 17.6 ± 0.3 | 163 ± 3 | 0.88 | 0.18 |
| With T4 | 96.1 ± 1.8 | 1.83 ± 0.26 | 2.9 | 245 ± 2 | 320 ± 2 | 26.5 ± 0.2 | 234 ± 3 | 0.96 | 0.21 |
FDRX and dDRX represent the volume fraction and average grain size of DRX grains, respectively. Texture Intensity represent intensity of (0002) basal planes. TYS, UTS, EL, CYS represent tensile yield strength, ultimate tensile strength, elongation and compressive yield strength. YR (yield asymmetric ratio) = CYS/TYS; n represent work hardening exponents.
