氢在灰铁铸件焊补开裂中的行为研究
1
作者 张瑞杰 史光远 《中原工学院学报》 CAS 2003年第4期35-38,共4页
 采用排液测氢法和插销试验法较系统地研究了氢对钢芯石墨化铸铁焊条施焊的灰口铸铁焊接接头冷裂倾向的作用;将试验结果与高强钢综合比较,得出灰口铸铁对氢致裂纹不甚敏感的结论.在微观上应用显微镜下录像测氢试验法观测焊接接头中氢...  采用排液测氢法和插销试验法较系统地研究了氢对钢芯石墨化铸铁焊条施焊的灰口铸铁焊接接头冷裂倾向的作用;将试验结果与高强钢综合比较,得出灰口铸铁对氢致裂纹不甚敏感的结论.在微观上应用显微镜下录像测氢试验法观测焊接接头中氢的动态行为,明确了氢的微观扩散行为及逸出过程.对此问题的研究不仅对工程实践具有较高的指导意义,更为进一步探讨灰口铸铁焊接接头裂纹产生原因提供了实验与理论依据. 展开更多

The HyFrance Group was originally formed in France to support the European project HyWays, by providing (former projects HyFrancel and HyFrance2) the French data and possible hydrogen pathways according to national specificities. HyFrance3 is a new project that focuses on the economic competitiveness of different steps of the hydrogen chain, from the production to end usage, at the time horizon of 2030 in France. The project is coordinated by CEA with the other partners being: ADEME (co-funding), AFH2, CNRS, IFP, Air Liquide, EdF, GdF Suez, TOTAL, ALPHEA. The project is divided into 4 sub-projects, that address present and future French hydrogen industrial markets for chemical & refinery uses, the analysis of the interplay between wind energy production and storage of hydrogen for different automotive requirements (refuelling stations, BtL plants, H2/NG mix), massive hydrogen storage to balance various offer and demand characteristics, and the supply network (pipeline option competitiveness vs. trucked in supply) to distribute hydrogen in a French region for automotive applications. Technical and economical issues, as well as GHG emissions, are addressed. 展开更多
