Description
Известен способ диффузионной сварки ме/гд .-.ЮВ с предаар тельнэй их обработкой.There is a method of diffusion welding IU / GD .-. SE with the pre-treatment with their processing.
Иредлага8 1ь;й способ отличаетс от извести ог о тем, что дл снижени температур / сварки гфоизБод т предварительную термичесхую обработку с образованием метастабил .ькь.х фаз. а сварку ведут при температуре распада этих фаз.This method differs from lime in that in order to reduce the temperature / welding of the body it is a preliminary thermal treatment with the formation of metastable phases. and welding is carried out at the decomposition temperature of these phases.
В результате термообработки получают метастабиль-ггг ге , например мартенсит дл стали. Во врем нагрева под сварку при темпера; уре растсада мартенсита подвижность .-. томов за счет распада неравновесной структуры йозрастает, что приводит к интенсификации диффузионных процессов. Температура распада метастабильных фаз значительно ниже 0,8 т. пл. металла, т.е. обычной температуры диффузионной сварки.As a result of heat treatment, metastable-yyyy ge, for example martensite for steel, is obtained. During heating for welding at tempera; Ura herdsten martensite mobility .-. due to the decay of the nonequilibrium structure, it grows, which leads to an intensification of diffusion processes. The disintegration temperature of the metastable phases is well below 0.8 tons. Pl. metal, i.e. normal diffusion welding temperature.
