The aluminium
interaction with cobalt and titanium
Abstract
The aim of present investigation is
studying of aluminium interaction with Co and Ti by construction of isothermal
(at 6000C) and polythermal sections. The experiment was carried out by X-ray, X-ray microprobe,
microstructure, differential thermal analysis’s and microhardness and hardness
measurements. It was established, that
between intermetallics Al3Ti and Al9Co2 the
interaction by eutectic type with limited components solubility is realized;
but in other case, as a result of AlCo and TiCo interaction, the ternary
compound AlCo2Ti is formed. For a first time, in present research
the temperatures, ways of formation and boundaries of homogeneity regions of
ternary compounds Al15Co8Ti6 and AlCo2Ti
were determined.
