Turn-back diffusion of interstitial elements in weld joints of steels

Investigator: Ing. Bořivoj Million, DrSc.
Number of Project: 106/01/0382
Agency: Czech Science Foundation
Duration: 01. 01. 2001 - 31. 12. 2003

It may be expected, with respect to the previous measurements, that in a weld joint of the steels (creep resisting steel P91)/(stainless steel 18/8) the C and N diffusion from the steel P91 into the steel 18/8, as well as in opposite direction will occur.
