In this work, the chemical composition of carbide was changed at shock loading. The formation of austenite from ferrite or pearlite and the change of carbide composition runs as a result of diffusion processes, therefore it was supposed, that as a result of micro- and macro-plastic metal deformation, which is conducted by heat evolution, the iron diffusivity in local amounts of the alloy should increase considerably and therefore it should be dissolved in carbides. The increase of iron contents took place in carbides of M7C3 and M23C6 as a result of tempering or contact-shock circular loadings at the expenses of diffusion processes. It was explained that strengthening phase of developed alloy 2M3 was carbides MC, M7C3 and M23C6.
