Thermal Stability |
| |
The single greatest advantage for B-3 alloy over B-2 alloy accrues from its ability to maintain excellent ductility during transient exposures to intermediate temperatures. Such exposures are routinely experienced during heat treatments associated
with fabrication. While very short exposures at temperatures such as 1290°F (700°C) can severely embrittle B-2 alloy at temperature, B-3 alloy exhibits a marked resistance to such embrittlement for up
to several hours. This provides far greater facility for the alloy to be
fabricated into complex components such as formed heads.
