抄録

The efect of Al contents on the age-hardening of 70Ni-30Cu alloys has been investigated by Rockwell-and micro-hardness, microscopic and corrosion test. The following results have been obtained. (1) The maximum hardness was obtained by aging at 590°C for 12 hrs and more, or at 640°C for 2∼6 hrs. (2) The alloy containing 3.0∼3.5%Al has been found to be the most age-hardenable. (3) Against boiling in 20 wt%H2SO4, full-and over-aged alloys showed corrosion resistivity superior to that of solution-treated alloys and plain Ni-Cu alloys.
