摘要註:	本研究為了解SCM435球化退火製程退火後之機械性質與微組織的關係,以利後續機械加工,本實驗利用田口實驗設計簡化實驗次數,並以不同時間與不同溫度材做為實驗因子,運用田口實驗設計為2因子四水準進行實驗測試,並利用拉伸試驗、硬度試驗、OM、SEM等收集機械性質與微組織之參數,以田口方法來做單一靜態品質特性分析並與微組織比較以了解其差異性。結果顯示不同退火溫度對於機械性質與微組織有顯著影響,機械性質隨著持溫溫度升而顯著下降,而肥粒鐵相分率也以正相關之趨勢成長,但球化率在此參數下與持溫溫度及時間之變化並不明顯;當退火持溫溫度為750℃其機械性質與微組織之變化皆較730℃及710℃明顯,但770℃時抗拉強度會有略微上升之現象;而持溫時間的增加,對於機械性質而言有緩慢之下降趨勢,微組織散佈更為均勻;使用田口方法分析770℃-10hr為較理想之參數設計,但由微組織觀察與機械性質測試結果,發現在退火持溫溫度750℃在較短持溫時間時,碳化物分佈較為均勻,雖機械性質略高於770℃,在經濟效益考量下可以設定其生產參數得到較佳之生產效率,也說明田口實驗設計要廣泛的應用在產線上時,除了時間溫度外,應考慮其他影響因子如:碳化物大小、組成、散佈情形及經濟效益等,以利整體效能提升。 In this study, it would understand that how spheroidizing annealing process affected the microstructure of SCM435 Cr-Mo steel and how the microstructure changed the mechanical properties. Our aim was figure out which kind of microstructure would be good for mechanical deformation. In this experiment, experiments reduced by Taguchi method. Applied the Taguchi method to set up two-factor and four- level for testing in spheroidizing annealing. And Test bars of SCM435 Cr-Mo steel would be tested by mechanical properties, OM and SEM. The results showed a significant effect on the annealing temperature about mechanical properties and microstructure. Mechanical properties appeared to decline with increasing temperature and time. But spheroidization ratio was non-significant in this experimental parameters. In Taguchi method, spheroidizing treatment of 770℃ holding temperature and 10 hours holding time was the best. But spheroidizing treatment of 750℃ holding temperature would be improved economic efficiency.
