... Metal dusting of heat-resistant alloys occurs in carbonaceous atmospheres at temperatures above 425 °C (800 °F), with very high activity in the range of 790 to 845 °C (1450 to 1550 °F)and above 925 °C (1700 °F) ( Fig. 6 ). Carbon adsorption and diffusion into the metal matrix induce the formation...
