PEELS of STEELS

摘要

Some of the salient results of parallel electron energy loss (PEELS) studies of the detection, distribution and quantification of carbon in various steels are presented. The feasibility of deecting C in ultra low carbon alloy steels containin gas little as 0.03wtpercent C by PEELS is demonstrated followed by examples of electron energy loss images showing C partitioning between retained austenite and ferrite or martensite. In addition, an example of C and Mo segregation to ferrite: martensite interfaces during diffusional austenite decomposition in a Fe-C-Mo steel is presented.
