Effect of solidification processing parameters on the cellular spacings in the Al–0.1 wt% Ti and Al–0.5 wt% Ti alloys
چکیده انگلیسی

The aim of this work is to investigate the relationship between solidification processing parameters (temperature gradient, G, growth rate, V  , and cooling rate,T˙) and cellular spacing, λ, in the Al–0.1 wt% Ti and Al–0.5 wt% Ti alloys grown at high growth rates. In order to achieve this aim, the specimens were solidified under argon atmosphere and steady-state conditions upward with different temperature gradients, G at a constant growth rate, V and with different V at a constant G for the Al–Ti alloys in the Bridgman type directional solidification apparatus. The cellular spacing, λ was measured and expressed as functions of solidification processing parameters, G, V   and T˙ by using a linear regression analysis. The results were compared with similar previous experimental work and current theoretical models suggested for cellular growth.
