Abstract:	中文摘要　　利用擠鍛及抽拉之技術，我們將緊密結合在一起之五十對五十重量百分比之銅鋅金屬粉粒混合體之截面縮小約200倍而成未經熱處理過之多絲狀細線，在絕對溫度350度至650度區間內，我們已仔細的研究了電阻係數隨溫度之變化關係。此外，等溫不可逆電阻係數之變化亦在攝氏溫度150度，250度，350度及570度分別進行。依據我們的實驗結果判斷，此種多絲狀銅鋅複合材料若在攝氏溫度150度至350度間經熱處理後則會產生合金效益，並逐漸改變其性質；但當熱處理兩天以上則將達平衡狀態。多絲狀銅鋅複合材料若一直保持在低於絕對溫度390度以下時，合金效益將不易發生，故可保持其原有之複合材料特性。 Abstract 　　Compacts of Cu-50 wt. % Zn powders were reduced in cross section to produce multifilamentary thin wires. Swaging and drawing techniques were used to achieve an areal reduction of about 200 without any intermediate anneals. The temperature-dependent electrical resistivity was studied between 300K and 650K. The isothermal irreversible electrical resistivity changes due to anneal effect was studied at 150 C, 250 C, 350 C and 570 C. According to our experimental data, the alloying effect in multifilamentary Cu-Zn system is completed after annealing at temperatures between 150 C and 350 C for 2 days; and the multifilamentary Cu-Zn thin wire can be annealed at least with a few hours at temperatures below 390K without any alloying effect.
