Abstract
The penetration depth of Ti ions extracted at 30 kV from a metal vapou r vacuum arc source reaches 130 nm in H13 steel for a 5 x 10(17) cm-2 doping and is reduced to 60 nm for 1.5 x 10(19) cm-2. The retained con centration is 21 at.% and 49 at.% respectively. The substantial struct ural change is the formation and growth of Fe2Ti, FeTi etc., and Fe2Ti precipitate becomes dominant at very high doses. The local electronic environment around Fe sites is distinctly altered owing to the intera ctions with Ti and the bonding state of Fe atoms is greatly enhanced.
