A FRESH LOOK AT THE PROBLEMS IN BERYLLIUM METALLURGY
Technical Report
·
OSTI ID:4804191
The current status of beryllium metallurgy is reviewed. The nonsystematic variation in the mechanical properties, particularly the low room temperature and the ductility minimum around 600 deg C, are its most disturbing features. Recent work shows that the 600 deg C ductility minimum can be eliminated by overaging of controlled compositions, which means that commercial beryllium may be considered as a complex, unstable age-hardening alloy rather than as a somewhat impure dilute alloy. The implications of this on the room temperature properties are discussed. Some comments on the technological problems and analytical requirements are made. (auth)
