| 中文概述 Chinese Description | 使學生瞭解塑性變形對材料機械性質、物理性質、及化學性質之影響，實習內容如下： 1.鋼鐵、非鐵材料在各種加工度下之機械性質變化實驗；2.不鏽鋼料（18-8不鏽鋼）在各種加工度下之耐蝕性比較實驗；3. 線材之抽拉實驗，各種潤滑劑對抽拉力之影響；4.加工硬化對退火處理之組織變化，結晶粒大小之影響；5.壓軋加工下之變形實驗；6. 鍛造加工實驗；7.板材之引伸加工實驗。實驗內容主要分成兩大類，A.為材料加工製程實習，包含板材輥軋加工、棒材旋鍛實驗、線材盤元抽拉實驗、薄板沖壓實驗、塑料射出成形。B.為材料進階機械分析，包含塑性Luder's band 現象、金屬之雙晶與滑移破壞分析。 | |||
| 英文概述 English Description | This lab course makes students understand the effects of plastic deformation upon mechanical, physical and chemical properties of metals. The course includes: 1. mechanical properties of ferrous and non-ferrous metals under different degree of plastic strain; 2. corrosion properties of 18-8 stainless steel; 3. tension tests of wires using different lubricants; 4. change of grain size with strain and annealing; 5. deformation by rolling; 6. forging; and 7. wire drawing. The main experiments will focus on: A. processes of plastic deformation including, rolling, swaging, wire drawing, plate pressing, plastic injection forming, and B. the observations of Luders’ bands, twinning, and slips in plastic deformation and fractures. | |||
