Influence of growth rate on microstructure, microhardness, and electrical resistivity of directionally solidified Al-7 wt% Ni hypo-eutectic alloy
(KOREAN INST METALS MATERIALS, 2013)
Al-7 wt% Ni alloy was directionally solidified upwards with different growth rates, V (8.3-489.5 mu m/s) at constant temperature gradient, G (4.2 K/mm) using a Bridgman-type growth apparatus. The dependence of the dendritic ...
Mechanical, electrical, and thermal properties of the directionally solidified Bi-Zn-Al ternary eutectic alloy
A Bi-2.0Zn-0.2Al (wt%) ternary eutectic alloy was prepared using a vacuum melting furnace and a casting furnace. The samples were directionally solidified upwards at a constant growth rate (V = 18.4 mu m/s) under different ...
Effects of Cooling Rate and Composition on Mechanical Properties of Directionally Solidified Pb100-x-Sn-x Solders
Pb100-x-Sn-x solders (x = 5 wt.%, 10 wt.%, 20 wt.%, 35 wt.%, 50 wt.%, 60 wt.%, 61.9 wt.%, and 95 wt.%) were directionally solidified upward over a wide range of cooling rates (T) over dot (0.016 K s(-1) to 4.0 K s(-1)) by ...
Measurements of Microhardness and Thermal and Electrical Properties of the Binary Zn-0.7wt.%Cu Hypoperitectic Alloy
Zn-0.7wt.%Cu hypoperitectic alloys were directionally solidified upwards with different temperature gradients (3.85 K/mm to 9.95 K/mm) at a constant growth rate (0.042 mm/s), and with different growth rates (0.0083 mm/s ...
