摘要

本文目的在於利用加入不同鈦含量來探討其對肥粒鐵系抗菌不銹鋼之機械性質、集合組織與抗菌性之影響。由於添加鈦可改善條紋性質與深衝性，但是如果添加過量而引起過量介在物或析出物時，則會傷害擴張性質與表面性質。此外，在肥粒鐵系抗菌不銹鋼中添加鈦，會形成TiC、TiN析出物，在其周圍有助於ε-CU相均一析出，此作用在Ti 0.02wt%以上較為顯著，但是超過1 wt%時，會使製造性及加工性降低。本研究將以真空電弧精煉方式配置不同鈦含量試片，經熱軋、冷軋製程，並施以抗菌處理，以拉伸試驗、硬度試驗、顯微組織觀察，極圖分析以及ESCA分析來探討各種不同鈦含量對機械性質與條紋性質以及ε-Cu相析出的影響。

The goal of this proposed research is to investigate the effects of titanium content on mechanical properties, texture and antimicrobial activity of antimicrobial ferritic stainless steels. Addition of titanium can minimize ridging and increase plastic strain ratio of ferritic stainless steels. Titanium has a greater affinity for carbon and nitrogen than chromium, binding the carbon and nitrogen as TiC and TiN. TiC and TiN are favorable to the uniform precipitation of ε-Cu phase in antimicrobial ferritic stainless steels. When titanium content is over 0.02 wt%, this effect is obvious. But when titanium content is over 1 wt%, it could deteriorate the workability of steel. In this research the vacuum arc refining method will be used to melt the specimens with different titanium contents. After hot rolling and cold rolling, specimens will be conducted with antimicrobial treatment. In order to study the effect of titanium content on the mechanical properties, texture, ridging and antimicrobial activity of antimicrobial ferritic stainless steels, tensile test, microstructure observation, pole figure and ESCA analysis will be used.
