Effects of Furnace Moving Velocity on the Growth Behavior and Microstructure of Directionally Solidified Al-15Cu-1Mg Alloy |
| Abstract |
14㎝ length Al-15Cu-1Mg alloys in 3㎜ I.D. alumina tubes have been directionally solidified under the furnace temperature of 760℃. Furnace moving velocity(V) was changed with the range 0-120㎝/hr. By analysing the evolution of the temperatures profiles along the specimen length, the growth characteristics-the position of the solid/liquid interface, temperature gradient(G) and local growth velocity(R)-have been examined. The microstructures of the alloys have been observed for the investigation of microstructural uniformity along the specimen length and the effects of the furnace moving velocity(V). |
