Paper Abstract

The microdeformation characteristics of a new instrunent grade of beryllium 1-250 are presented and compared to previously available conunercial grades. The importance of iuicroyield strength to mirror stability under mechanical and inertial loads as well as under temperature excursions is discussed and related to the HCP crystal structure. It is concluded that 1-250 may provide significantly improved dimensional stability over 1-70 or 0-50. 1.
