Abstract
The presence of easy-diffusion paths is very important for fast format ion or healing of a protective Cr-rich oxide scale for resistance of c hromia-forming steels against metal dusting. Such easy-diffusion paths , grain boundaries, subboundaries, and dislocations are provided by a fine-grain microstructure, cold and/or surface working-polishing, grin ding, machining, sand blasting. Their importance and effectiveness are demonstrated by various laboratory results and also by a failure case and their appearance is shown by TEM studies on ground steel specimen s.
