OSTI ID:4069039
Several beryllium single crystals were prepared by the floating zone method of zone melting. These crystals, tested in tension, exhibited extensive basal plane glide prior to fracture. These observations represent a significant increase in ductility in comparison to previously reported work. The increased ductility of the zone-melted crystals is discussed with respect to the purification attained and also with respect to the role of impurities in the presently proposed fracture mechanisms of beryllium.
