| 摘 要： | Effects of melt temperature and casting speed on microstructure and mechanical properties of Cu-14%Al-3.8%Ni(mass fraction) alloy wires fabricated by continuous unidirectional solidification technology were investigated.It was found that the average size of columnar grain in the alloy decreased and grain boundary turned clear and straight with increasing the casting speed at a given melt temperature.When the melt temperature was up to 1 280℃,theβ_1 phase gradually transformed into lozenged and lanciformγ...
