抄録

The effect of V,Nb and W on the properties of Ni-Mo-Cr alloys was investigated by hardness, tensile, microscopic and corrosion tests. The corrosion test was carried out on specimens in boiling 2 wt%HCl for 24 hours. The following results were obtained. (1) With increasing content of V and Nb, both the corrosion loss and the strength of solution-treated Ni-Mo-Cr alloys increased, but those of the alloy containing W showed no remarkable variation. (2) The alloy containing 5%W annealed at 700°C and 800°C showed superior corrosion resistivity, but the alloy V and Nb annealed at the same temperature showed corrosion resistivity inferior to that of plain Ni-Mo-Cr alloys. (3) Upon age hardening at high temperature, the relation between the hardness and the contents of added elements was not always consistent.
