Abstract
The aim of this paper is to demonstrate the application
possibilities at using diffusion bonding for creation the
homogenous joints regarding their strength properties in
comparison with the fusion MMAW method and with the
parent material. Connection was carried out for low-alloyed
bainitic steel 10GN2MFA that is designed for production shells
and bodies of the primary steam-generators collectors which
are used in the nuclear power industry. In the paper are
theoretically described the basics of diffusion. Moreover, there
is described also the proposal and optimization of the diffusion
bonding process parameters and optimization of the thermal
treatment procedure. Experiments were carried out by means
of the thermal-mechanical simulator Gleeble 3500. Welded
joints were subsequently evaluated in light of mechanical
properties by hardness measurement and metallography.
