%X TEM observation in situ on the single-side thinned specimens wasmade of the nucleation and growth of borides during boronization of steel 20 andthe influence of prior room temperature deformation. The results of X-ray diffrac-tion and electron probe microstructure analysis show that only Fe_2B formed inthe surface layer of specimens at the beginning of boronization; the atomic concen-tration of B in the surface layer increased with the increase of deformation mon-otonously; and the segregation of B atoms in the dislocation cells hindered the re-covery and recrystallization of the deformed structure of the matrix and accelara-ted the nucleation and growth of borides in the surface layer.
