PLASTIC ANISOTROPY AND FRACTURE IN BERYLLIUM
Journal Article
·
· J. Nuclear Materials
The relation between plastic anisotropy and ductility in beryllium between 20 and 400 deg C is explored. Features of the plastic deformation and fracture of single crystals are discussed. They include basal slip, bend plane formation and splitting, crack initiation, and propagation. Comparison is made with basal fracture observed in zinc, and Stroh's theory for this type of fracture is applied to beryllium. The deformation and fracture of a polycrystalline aggregate is also discussed, and a qualitative explanation is proposed for the increase in ductility with temperature. Possible means of improving ductility are suggested. (auth)
