1060. FORESTIER, H., AND NURY, G. [Variation of the Velocity of Cementation of Iron at the Temperature of the Curie Point.] Compt. Rend., vol. 227, 1948, pp. 280-282; Chem. Abs., vol. 43, 1949, p. 472. Velocity of cementation of Fe at temperatures 600°-800° was followed by 2 methods: Variation of electric resistance of wires and hardness of polished faces of cubes. The velocity was a maximum at the Curie point, about 775°. |
