低碳鋼在銲接時,於銲處周圍的粗晶熱影響區會產生沃斯田鐵晶粒成長的現象,為了解決這個問題,添加鎂於低碳鋼中,可有助於阻止晶粒成長.本研究探討添加不同鎂含量的低碳鋼SS400在高溫下晶粒成長的影響,使用晶粒成長公式預測不同熱處理溫度及時間下沃斯田鐵晶粒尺寸. 本研究將試片使用高溫共軛焦雷射掃描顯微鏡(HT-...
In this study, the effect of welding parameter such as rotational speed on the mechanical properties and microstructure of friction stir spot welded Al 5052 and SS400 sheet have been investigated. The rotation speed of 1250, 1600, 2000 rpm and the dwell time of 10, were applied to fabricat...
Thermodynamic calculation has been applied to predict the inclusion formation in molten SS400 steel. When the Cerium addition in liquid iron is 70 ppm and the initial Oxygen and Sulphur are both 110ppm, the formation of oxides containing Cerium would experience the transformation from Ce2O3 to ...
