Abstract:

A review is given of the status of investigations at the end of the year, the primary approach still being X-ray techniques. The investigations included 1 determination of fault probability in the presence of applied or residual tensile stress for alpha brass in tension where the probability for a given strain is low AD-602 114 2 X-ray diffraction from niobium and tantalum deformed by wire drawing 3 peak shifts caused by layer faults in Cr-1 Re and Cr-35 Re alloys 4 X-ray diffraction from explosively deformed silicon bronze where line broadening appears to be caused by particle size not strain 5 methods for calculation of electron diffraction patterns containing twin reflections 6 elliptical diffraction patterns from faults in graphite 7 possible standardization of crystallographic formulas for hexagonal lattices and 8 extrinsic faults for cerium deformed by filing at room temperature as shown by peak shifts.
