The change in electrical resistance of Pd-, Cu-, Ni- and Fe-base metallic glasses in tensile process and the effect of composition, cold deformation and heat treatment on the strain coefficient of resistance k, have been investigated. The results show that the resistivity increases with the increase of strain and K is positive. K of all the alloys are always less than those of pure metals; k of cold deformed state and annealed state samples are greater than that of rapidly quenched state samrte. The physical nature of K and its factors of influence on metallic glasses are discussedpl in virtue of generalized Ziman theory.
