TEM-analysis was supported in part by the Nanotechnology Support Project of the Ministry of Education, Culture, Sports, Science and Technology (MEXT), Japan . The authors thank Dr. Yoshitaka Misaka and Dr. Kazuhiro Kawasaki of Netsuren Co. Ltd. for conducting the SRIHQ, and Mr. Shoichi Toh and Ms. Rika Ohkubo of the Research Laboratory for High-Voltage Electron Microscopy of Kyushu University for their assistance in EDS-analysis. A part of the TEM-observation was carried out by using a facility in the Research Center for Ultrahigh-Voltage Electron Microscopy, Osaka University. The authors thank Professor Hirotaro Mori and Dr. Eiji Taguchi of the center for their help. This research was partly supported by the ISIJ Research Promotion Grant.

N2 - Microstructures and hardness of a Fe-1.4%Cr-1%C pearlitic steel processed by super-rapid induction heating-and-quenching (SRIHQ) under various conditions have been investigated. A nano-scaled laminated microstructure composed of two different types of martensite (highly-twinned or containing a high dislocation density) was formed and the maximum hardness was obtained by heating to 1223. K in 0.5. s and quenched. Electron energy loss spectroscopy indicated that the two different types of martensite were formed depending on the local solute-concentration in the non-uniform solute-distribution realized by the SRIHQ-process.
