Effect of external friction on deformational aging of steel taking into consideration its thermal treatment
Abstract
Features of external friction effect on the process of natural aging of carbon steel after different thermal treatment was studied by amplitude-dependent and amplitude-independent methods of internal friction. Determined, that natural aging of steel is conducted by primary growth of internal friction as a result of relaxation processes development with further de-creasing internal friction level, generated by blocking of dislocations. It is showed, that external friction decelerates devel-opment of deformational aging of martensite structures, but considerably activizates this process in the case of high-temperature tempering of steel on late stage of agingReferences
