✦ Synopsis


The cold-work distortion of zirconium was studied by means of an X-ray method which involves an interpretation of the shapes of the broadened peak profiles. This approach (l) had been applied extensively to materials of cubic symmetry(2), and to a study of imperfections in cobalt.(3) Broadening effects arising primarily from particle size and strains are expected for zirconium, with stacking faults less likely to occur. The metal is ductile at room temperature and deforms by slip and twinning processes.c4) Crystal bar zirconium containing 235 p.p.m. 0, 220 p.p.m. Fe, and 110 p.p.m. C, as the principal impurities was used. The hydrogen content of about 40 p.p.m. was lowered to about 3 p.p.m. by annealing The authors are indebted to Messrs. C. Houska and S. Allen for several valuable discussions,
