這篇研究主要是探討0.63C-12.7Cr 麻田散鐵不銹鋼在不同回火條件下之顯微結構及機械性質之改變.從實驗結果顯示微小之初析碳化物出現在此材料中,從硬度測試發現在回火條件300 C,60分鐘之情況下硬度值仍可維持在677Hv.同時回火溫度介於200 C–500 C時,硬度值之變化也不是太顯著.另外由於此材料之低碳及铬含量,麻田散鐵相之轉換溫度可提升至96.4 C. In this study, the microstructure and mechanical properties of 0.63C-12.7Cr martensitic stainless steel during various tempering treatments were investigated. Experimental results demonstrate that finely distributed primary carbides can be observed in 0.6
