Variation of microindentation hardness with solidification and microstructure parameters in the Al based alloys
(ELSEVIER SCIENCE BV, 2008)
The Al based alloys (Al-3 wt%Si, Al-3 wt%Cu and Al-1 wt%Ti) were prepared using metals of 99.99% high purity in the vacuum atmosphere. These alloys were directionally solidified upward with a constant growth rate (V = 0.008 ...
Investigation of directional solidified Al-Ti alloy
(ELSEVIER SCIENCE BV, 2009)
Al-1 wt% Ti alloy was directionally solidified upwards under argon atmosphere under the two conditions; with different temperature gradients (G = 2.20-5.82 K/mm) at a constant growth rate (V = 8.30 mu m/s) and with different ...
