Abstract

Scanning electron microscopy, electron probe microanalysis, X-rays diffractometry, and microhardness measurements were used for studies of diffusion zones in systems Al-Тi, Al-Co, and Al-Ni formed by means of diffusion couples method in a temperature range of 1,300-1,350 °С. It was shown that diffusion zones have the multilayer structure with numerous peculiarities. For a number of intermetallic compounds formed in all three systems there were revealed their temperature shifts using the electron probe microanalysis methods and confirmed with X-rays diffractometry. The correlation between the individual intermetallic layers and their microhardness numbers are not always evident. For some aluminides the microhardness can reach 7,060 ± 1,200 MPa (in globular area of Ti5Al11 and TiAl) and 4,938 MPa (in multilayer area of titanium aluminide TiAl₂). For very thin (about 10 μm) layers in multilayer area the microhardness has been measured in the first time 4,000 MPa (TiAl) and 4,450 MPa (Ti₃Al). The obtained microhardness numbers demonstrated reasonable coincidence with previous published results. Microhardness in Al-Ni system was measured as 5,200 ± 500 MPa (for β-NiAl) and 5,300 ± 860 MPa (for γ΄-Ni₃Al). For cobalt aluminide СоАl from Аl-Со system the microhardness showed numbers 3,900 ± 200 MPa, whereas for СоАl₃ it was higher up to 6,600 MPa. The intermetallic compound γ΄-Ni₃Al considered as the most interesting from practical point of view had small (up to 10 μm) width whereas the next layer Ni₃Al₅ had the wider (100 μm) width. There were also revealed some globular Ti₅Al₁₁ having thin shells which consist of intermetallic Ti₉Al₂.
