Calculation of the substitutional fraction of ion-implanted He in an Fe target
, 2010 Ion-implantation is a useful technique to study irradiation damage in nuclear materials. To study He effects in nuclear fusion conditions, He is co-implanted with damage ions to reproduce the correct He/dpa ratios in the desired or available depth range.

Dynamic Precipitation during High‐Pressure Torsion of a Magnesium–Manganese Alloy
Advanced Engineering Materials, EarlyView.An ultrafine‐grained alloy is produced by high‐pressure torsion of solutionized Mg–1.35 wt% Mn. Precipitation of nanometer‐scale Mn particles during deformation provides pinning sites. This prevents the formation of a bimodal grain structure and results in a finer grain size than for pure Mg.
