摘要: Abstract Two types of hardening were observed on ageing after quenching Cu wire, depending the temperature. A comparison quench in and Au with decay quenched-in resistivity shows that two can be explained assuming sinks for vacancies as discussed Part I. For high temperatures, is considered to due formation sessile rings; low annihilation at pre-existing dislocations. Detailed mechanisms are discussed. The activation energies migration single- di-vacancies found about 0.7 eV 0.6 eV, respectively.
