couples obtained by the Transient Liquid Phase Bonding (TLPB) process at temperatures
ranging from 800 C to 1000 C. The crystal structure and the chemical composition of the
phases formed, including the AlNi intermetallic, were evaluated using TEM-EDS. The evolution
of the AlNi layer as a function of bonding time was studied by in situ high energy synchrotron
x-ray diffraction. The AlNi lattice parameter increases up to 2.9401 A˚ and subsequently
decreases with the annealing time due to changes in the chemical composition of AlNi. This
behavior is related to the formation of two distinct layers of AlNi: Al-rich AlNi and Ni-rich
AlNi. The split of the AlNi phase indicates that a chemical partition takes place when Ni and Al
atomic concentrations are approximately equal. The growth kinetics of both layers are
controlled by diffusion with different growth rate constants. These results contribute to the
understanding of the solid-state transformations occurring in a multicomponent and multilayered TLP bond under isothermal conditionsPracoviště Ústav fyziky materiálu Kontakt Yvonna Šrámková, sramkova@ipm.cz, Tel.: 532 290 485 Rok sběru 2022 Elektronická adresa https://link.springer.com/article/10.1007%2Fs11661-021-06159-y
