dc.description The electrical resistivity rho of a metal can be expressed as rho = rho <sub>I</sub>+ rho <sub>T</sub>+ rho <sub>CW</sub>+ rho <sub>GB</sub> where rho <sub>I</sub> and rho <sub>T</sub> are the components of the resistivity due to impurities and lattice vibrations respectively. rho <sub>CW</sub> is the component of the resistivity due to cold work while rho <sub>GB</sub> is that due to grain boundaries. Both rho <sub>CW</sub> and rho <sub>GB</sub> will change on annealing. rho <sub>CW</sub> will be reduced as the imperfections anneal and rho <sub>GB</sub> will decrease with grain growth. Unfortunately these effects are usually masked by changes in rho <sub>T</sub> except under high stability isothermal annealing conditions. The technique described represents a novel method of suppressing rho <sub>T</sub> and allows direct measurement of rho <sub>CW</sub>+ rho <sub>GB</sub>. This makes possible the in situ monitoring of industrial annealing processes.
