【Abstract】 The low alloyed steels wth boron content varying from 0.15% to 0.55% are produced by means of the vaccum induction melting method. The microstructure of B and Fe element interaction is studied on the basis of x\|ray diffraction and Mossbauer spectra analysis. We discover that the basic parameter of the Müssbauer spectra—Isomer shift, quadrupole splitting and hyperfine magnetic field change with the composition of the high B steel. Experimental results show that a little B element is solid\|soluted in α Fe and most of the B element form Fe 2B and FeB compounds. The features of how B and Fe change and the reasons for the change in the hyperfine structure have been analyzed.更多还原
