-resistant Al-0.15Zr conductor with different amounts of Ce were studied by means of electrical resistivity measurement, hardness test, optical microscopy and scanning electrical microscopy. The results show that metallic compound containing Ce and impurity are congregated at the grain boundary and dendritic boundary, which is beneficial to the electrical conductivity and strength. Alloying of Ce......
before the microhardness measurement. Keithley model 6157 electrometer (made in USA) was used to measure the electrical resistivity of the as-prepared nc-Cu at 233-293 K. Sirion200 FESEM was employed... nanocrystalline metals was characterized by XRD and FESEM. The microhardness and electrical resistivity were tested by the HMV-2 type Microhardness Tester and 6157 type Electrometer, respectively......
