The influence of various gases on the graphitization in white cast iron. The author carried out the present investigation by devising a dilatometer of new type in which a specimen of white cast iron can be annealed in a voluntary atomosphere, and found the following important new facts:-
(1) In the atomosphere of carbon dioxide, the graphitization in the first stage ofwhite cast iron completes in a far shorter time than in that of other gases.
(2) Nitrogen is not indifferent to the graphitization in white cast iron.
(3) Hydrogen, ammonia and methane strongly retards the graphitization in white cast iron.
