Recommended Research to Protect Coal Liquefaction Vessels Against Non-Ductile Failure

摘要

The concepts of fracture mechanics are used routinely to guarantee the structural integrity of components. General guidelines for performing a fracture analysis are provided in Appendix A to Sect. XI of the ASME Boiler and Pressure Vessel Code. Those guidelines apply directly to coal liquefaction vessels; however, the data base necessary for the analysis does not exist. The available literature on candidate materials (2-1/4 Cr-1 Mo steels) is reviewed, and recommendations are made on the range and scope of the research programs needed to develop the fracture mechanics data base. 22 references, 13 figures, 3 tables.
