Effect of Deformation and Recovery on the Subsequent Resistivity Increase in Cold-worked Cadmium


RECENT experiments1 on copper have shown that, following deformation at 78° K and recovery at room temperature, the number of defects produced per unit strain increase during subsequent deformation. Apparently, during the recovery, a defect-enhancing defect is formed, the exact nature of which is at present not clearly understood. Similar experiments on metals the recovery spectrum of which is such as to have defects other than point defects mobile at the recovery temperature and also the effect of changes of crystal structure on this phenomenon have not as yet been investigated. It is the purpose of this communication to describe results obtained on cadmium and to present reasons why cadmium behaves differently from copper.
