抄録

Effect of C contents on the properties of Ni-Mo-Cr alloys has been investigated by hardness, tensile, microscopic tests and corrosion tests, made with specimens in boiling 10 and 2 wt%HCl for 24 hours. The following results have been obtained: (1) With increasing content of carbon, both the corrosion loss and the hardness of solution-treated Ni-Mo-Cr alloys increased, but the elongation was lowered. This may be attributable to an increase of eutectic carbide (M6C a=11.03 Å), the amount of which increased by addition of carbon. (2) After annealing at 700° and 800°C for 30 min, the higher carbon contents, the more appreciably deteriorated the corrosion resistance due to the continious precipitation of carbide on grain boundaries.
