Özet

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, lambda, 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,. 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. (c) 2006 Elsevier B.V. All rights reserved.
