Ion-implanted alloys have been used to study mechanisms of impurity immobilization in metals. These phenomena provide a means of suppressing detrimental impurity effects such as embrittlement. Processes investigated include the reaction of Al and Fe in Be to form AlFeBe/sub 4/ precipitates, the trapping of Sb in Fe by TiC and TaC precipitates, and the binding of hydrogen in Fe to lattice defects and to Y solutes. The broader applicability of the method of investigation is considered in the context of these examples.
