摘要：
The effect of hydrogen and helium on the physicochemical properties of ferritic steel has been investigated. Nondestructive testing was used: acoustic methods, nanoindentation, and the eddy-current method. A nonlinear dependence of the nanoindentation parameters and acoustic emission signals on the helium implantation dose is shown. It is established that helium implantation significantly increases the speed of sound, whereas hydrogen only slightly affects this parameter. © Allerton Press, Inc 2008.
