The object of the study was diffusion-hardening gallium solders and other composite components. The market is experiencing an active growth in demand for low-temperature assembly technologies, especially in the field of IoT, wearables, and microsensors. The growing interest in low-temperature solders is due to the fact that they have a very low melting point (≈ 29.8 °C), which makes them promising for heat-sensitive electronic components, flexible electronics, 3D assembly without high heating. However, there are problems with their use that need to be solved: gallium corrosion to many metals, surface oxidation leading to poor wettability, slow curing at room temperatures. An experimental study of the phase formation during the interaction of Fe, Ni and iron-nickel alloys 36Н and 50Н with liquid gallium and tin was conducted. During the research, it was found that the intermetallics that are formed do not always grow according to a parabolic dependence in the coordinates: the thickness of the diffusion layer and the contact time. After calculating the reactive diffusion parameters, it was found that the effective reactive diffusion coefficients during gallium contact in the Fe-Ga, Ni-Ga systems are higher than in the Fe-Sn, Ni-Sn systems. It was found that during the interaction of iron-nickel alloys with liquid gallium, the rate of formation of new phases can be regulated. Iron-nickel alloys with a high nickel content in gallium solder pastes can be used both as solidification accelerators and as stabilizers. The results obtained allow us to state that functional solders are one of the directions of modern microelectronics.
