摘要：
The presence of easy-diffusion paths is very important for fast formation or healing of a protective Cr-rich oxide scale for resistance of chromia-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, grinding, 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 specimens.
