FIELD: plastic working of metals, possibly manufacture of bimetallic articles, namely fuel elements of nuclear reactors.
SUBSTANCE: method comprises steps of assembling core blank and envelope blank; calibrating assembled blank due to taper drawing of wall of envelope; sealing assembled blank and subjecting it to thermal diffusion working. Assembled blank is twice subjected to axial pressure action, at first after assembling and then after calibration of assembled blank while applying pressure with effort sufficient for deformation of bottom portion of envelope blank but not exceeding lengthwise stability effort of core blank.
EFFECT: lowered gas saturation of assembled blanks, high quality joining of end surface of core blank and inner surface of bottom portion of envelope blank.
