PREPARATION, STRUCTURE AND PHYSICAL-PROPERTIES OF FE-RICH, CO-RICH AND NI-RICH MELT-QUENCHED RIBBONS CONTAINING ZR OR HF .2. ELECTRICAL-TRANSPORT PROPERTIES

A melt-spinning technique was used to produce TE-TL alloy ribbons with TE = Zr and Hf and TL = Fe, Co or Ni for compositions around the TL-r ich eutectic (about 90 at.% TL-content). A large amount of data on the room-temperature electrical resistivity and the thermopower as well a s on the temperature coefficient of resistivity between 77 K and 300 K is presented for these alloys with the aim to provide a complete char acterization of the reproducibility of the ribbon preparation and to d emonstrate the macroscopic homogeneity along the length of long ribbon s. The influence of atomic structure and chemical composition on the e lectrical transport properties of these alloy systems is also discusse d to some extent.
