The interaction of hydrogen with defects in metals is reviewed, with the major emphasis on ion-implantation studies. Experimental results for trap binding enthalpies of hydrogen to defects (such as vacancies, interstitials, dislocations, and bubbles/voids) are discussed, as is the lattice location of hydrogen trapped to these defects (mainly vacancies) obtained by the channeling technique. The experimental results are compared with theoretical predictions based on the effective-medium theory. It will be shown how an interplay between theory and experiment has recently enhanced our understanding of these hydrogen-defect interactions. 57 references, 11 figures.
