抄録
Magnesium may be effective as an additional element for Cu-Be alloy because its atomic size and size-factor for copper are fairly analogous to those of indium, cadmium, tin and antimony whose good effects on aging properties of Cu-Be have already been shown by the authors’ previous works. Considering this, the age-hardening and mechanical properties of Cu-1.6%Be alloys after the addition of around 0.5% magnesium have been examined. It has been proved that these alloys are insensitive to over-aged softening up to the aging temperature of 350°C and have excellent mechanical properties.<BR>Cerium and lanthanum are in a different category from the other additional elements examined so farin the respect that both of them form intermetallic compounds with copper which are stable up to fairly high temperatures and neither of them has any solubility for copper. Using samples of Cu-1.6%Be alloys containing 0.17% and 0.42% of a mixture of CeLa, the aging properties have been investigated. An intermetallic compound identified as CeCu6 is formed in these samples. In order to improve the aging properties, it is necessary to disperse this compound into the matrix by cold-rolling after solution treatment. Although the incoherent precipitation is not always supressed in these cold-rolled samples on aging, it appears as finely dispersed particles under the electron microscope. These alloys are insensitive to over-aging up to 350°C.
