【實習課題 2】

實習題目：

增材制造316奧氏體不銹鋼的鉛鉍腐蝕行為研究

Lead-Bismuth Eutectic Corrosion Resistance of 316L Stainless Steel manufactured by Selective Laser Melting

實習內容：

面向核用奧氏體不銹鋼部件加工困難、抗鉛鉍腐蝕性能不穩定等問題，利用增材制造技術開展奧氏體不銹鋼結構材料的快速制造、成分優化與抗鉛鉍腐蝕性能篩選；主要研究內容包括一下幾個方面：

1. 開展不同成分與打印、熱處理工藝奧氏體不銹鋼的550C條件下的鉛鉍腐蝕測試。
2. 探究微量元素添加對增材制造316L不銹鋼鉛鉍腐蝕性能的調控機制。
3. 研究增材制造316不銹鋼的晶粒尺寸、晶界形貌等因素對鉛鉍氧化腐蝕和滲透腐蝕的作用機制與調控方法。

Due to the difficulties in processing austenitic stainless steel parts for nuclear use and lead-bismuth eutectic corrosion, additive manufacturing technology is utilized for rapid manufacturing, composition optimization, and selection of resistance to lead-bismuth corrosion performance of austenitic stainless steel structural materials. The main research contents include the following aspects:

1. Conducting lead-bismuth corrosion tests on austenitic stainless steel with different compositions and printing and heat treatment processes under 550°C conditions.
2. Exploring the regulation mechanism of trace element addition on the resistance to lead-bismuth corrosion performance of additively manufactured 316L stainless steel.

Studying the mechanism and regulation method of the effects of factors such as grain size and grain boundary morphology of additively manufactured 316 stainless steel on lead-bismuth oxide corrosion and permeation corrosion.
