The experiment is divided into two parts: The first part is direct cold roll pure iron into different deformation of A%, B%, C%, D% and E%. The second part is anneal treatment after cold-rolled deformation 80%, and the anneal treatment temperature T1~ T5. Pure iron has yield strength 169MPa, tensile strength 257MPa and ductility 69%. The tensile strength is increased with increasing cold roll deformation. Cold-rolled deformation E% has yield strength 510MPa, tensile strength 548MPa, and ductility 15%. The corrosion rate is also increased with increasing cold roll deformation. Cold-rolled deformation E% has the highest corrosion rate 0.2285mm/yr and immersion degradation rate 0.1207mm/yr. Anneal treatment condition T1, 1 hour after cold-rolled deformation E%, which has the best mechanical properties, yield strength 506MPa, tensile strength 540MPa and increased ductility 21%. Recrystallization was observed with anneal treatment condition T5, 1 hour and has yield strength 180MPa, tensile strength 292MPa and increased ductility 62%.

碩士 === 國立成功大學 === 材料科學及工程學系碩博士班 === 101 === In this study, pure iron processed different thermomechanical treatment, expect to reach higher mechanical strength and maintain high ductility as the main purpose. The experiment is divided into two parts: The first part is direct cold roll pure iron into different deformation of A%, B%, C%, D% and E%. The second part is anneal treatment after cold-rolled deformation 80%, and the anneal treatment temperature T1~ T5.
Pure iron has yield strength 169MPa, tensile strength 257MPa and ductility 69%. The tensile strength is increased with increasing cold roll deformation. Cold-rolled deformation E% has yield strength 510MPa, tensile strength 548MPa, and ductility 15%. The corrosion rate is also increased with increasing cold roll deformation. Cold-rolled deformation E% has the highest corrosion rate 0.2285mm/yr and immersion degradation rate 0.1207mm/yr. Anneal treatment condition T1, 1 hour after cold-rolled deformation E%, which has the best mechanical properties, yield strength 506MPa, tensile strength 540MPa and increased ductility 21%. Recrystallization was observed with anneal treatment condition T5, 1 hour and has yield strength 180MPa, tensile strength 292MPa and increased ductility 62%.
