Effect of High Pressure on the Solidification of Al–Ni Alloy

The effect of high pressure on the microstructure hypo-peritectic Al–38wt.%Ni alloy was studied. results show that Al3Ni and Al3Ni2 phases coexist at ambient pressure. However, it becomes a typical hyper-eutectic when synthesized 2 GPa 4 GPa. Meanwhile, interface temperature calculated with combination BCT dendrite growth model, which is suitable for phase. According to highest principle, result shows phase dominates over 1–5 Finally, Debye potential energy under different pressures were researched. Based low specific heat-capacity curve. temperatures pressure, GPa, are 504.4 K, 508.71 K 515.36 respectively, in lowest point decreases increase
