Abstract
In the present work, dependences of lamellar spacing (λ), microhardness (HV), and ultimate tensile strength (σUTS) on growth rate (V) were investigated in the Al–Cu–Ti (Al–33 wt % Cu–0.1 wt % Ti) eutectic alloy. For these purposes, the Al–Cu–Ti eutectic alloy was solidified at a constant temperature gradient of 6.45 K mm–1 with a wide range of growth rates, from 8.58 to 2038.65 µm/s. Then, the values of λ, HV, and σUTS were measured on the directionally solidified Al–Cu–Ti specimens. The dependences of λ, HV, and σUTS on V in the Al–Cu–Ti eutectic alloy were experimentally obtained using regression analysis. The results obtained in the present work were compared with the similar experimental results in the literature.
