锆合金

Sponge zirconium was employed as raw material to prepare wedge-like specimens of Zr52.5Cu17.9Ni14.6Al10Ti5 quinary alloy by a tilt casting method using ladle-hearth-type arc furnace. The effect of active element Sc on the glass forming ability and crystallization kinetic parameters of the quinary alloy is investigated.

The coarse needle-like or nubby Al9FeNi phase existed in the cast microstructure of high content Fe and Ni alloy 2618(2#). After hot extrusion, it was broken into coarse multi-angle Al9FeNi particles. The contents of Fe and Ni have no effect on aging characteristic and the hardness of the alloy after aging.

含锆的高铁、镍2618合金经熔体高温过热处理后(4#)，在合金铸态组织中获得均匀细小的针片状Al_9FeNi相，热挤压后获得均匀细小的颗粒Al_9FeNi相；弥散Al_3Zr粒子的存在可使2618合金得到细小的再结晶晶粒组织，该合金既可获得较高的高温强度，还可获得较高的延伸率。

By the OM and SEM observation of solidification microstructure, the interfacial reaction between TiAl alloy and Al2O3 crucible was serious, and a large number of α-Al2O3 inclusion formed in the solidification microstructure. The interfacial reaction between TiAl alloy and ZrO2 crucible occurred only on the sample surface, but the crucible was not stable at high temperature and a tack coating was formed, clinging tightly with TiAl alloy. C element in the graphite crucible changed the original solidification path of TiAl alloy, and club-shaped γ-TiAl phases formed.

通过用光学显微镜和扫描电镜对凝固组织观察发现，TiAl合金与氧化铝坩埚之间的界面反应较为严重，在凝固组织中形成了大量氧化铝夹杂；TiAl合金与氧化锆坩埚的界面反应仅发生在试样表面，但该坩埚在高温下不稳定，并在试棒表面形成一层无法剥离的粘结层；石墨坩埚中的C元素改变了原有TiAl合金的凝固路径，生成了棒状的γ-TiAl相。
