摘要

本文目的是在於研究不同的含銅量經過不同的時效處理對抗菌沃斯田鐵系不銹鋼機械性質之影響。含銅不銹鋼具有廣大的應用性及較好的成形性，銅會影響沃斯田鐵系不銹鋼的部分特性，如：拉伸性質，應力應變。另外，含銅不銹鋼經抗菌處理後，會產生ε-Cu相的析出，而具有抗菌的效果；雖然抗菌不銹鋼具有高附加價值，而且目前在台灣尚沒有生產抗菌不銹鋼之經驗，故本研究將不同的含銅量使用真空熔煉，經過熱軋及冷軋處理後，再經過不同的時效處理，使其ε-Cu相析出，以及研究其銅含量及時效處理對抗菌不銹鋼的ε-Cu相析出及機械性質之影響。

The goal of this proposed research is to investigate the effects of copper content and aging treatment on ε-CU precipitation and mechanical properties of antimicrobial austenitic stainless steels .The copper-containing austenitic stainless steels have wide applications and good formability. Copper has rather unique effect on the tensile properties and strain hardening characteristics of austenitic stainless steels. ε-Cu phase precipitates in the matrix of Cu-containing austenitic stainless steel after antimicrobial treatment which provides this steel antimicrobial activity against various bacteria. Owing to the potential market of this steel, it is worthy to study it. Until now this antimicrobial austenitic stainless steel has not been produced in Taiwan. In this research the vacuum arc refining method was used to melt the specimens with different Cu contents. After hot rolling and cold rolling specimens were conducted with various aging treatments in order to study the effects of copper content and aging treatment on ε-Cu precipitates and mechanical properties of antimicrobial austenitic stainless steels.
