IMI834高温钛合金熔模铸造充型性能Investment casting mold filling capacity of high temperature titanium alloy IMI834采用10×10网格蜡网制备熔模铸造型壳，研究型壳预热温度、离心转速以及型壳面层材料对IMI834高温钛合金充型能力的影响。研究结果表明：在本实验条件下，当型壳预热温度为400~600 ℃，离心转速为300 r/min时，IMI834的充型性能最好。面层材料以CaO稳定的ZrO2和醋酸锆粘结剂制备的型壳充型性能远好于Al2O3和硅溶胶粘结剂制备的型壳的，表明界面反应对合金的充填性能有极大的影响。离心浇注实验结果表明：合金熔体在Coriolis力的作用下优先向与离心转向相反的方向充填。
The investment casting mold was prepared using wax pattern (10×10 squares with diameter of 0.5 mm). The mold filling capacity of high temperature titanium alloys IMI834 at different mold preheat temperatures, centrifugal speeds, and with different primary layer materials. The results show that IMI834 alloy exhibits the best mold filling capacity at the mold preheat temperature between 400 and 600 ℃ and centrifugal speed of 300 r/min. The primary material with ZrO2 (CaO stabilized) and zirconium acetate binder presents better mold filling capacity than the Al2O3material and silica gel binder, indicating that the mold filling capacity is greatly influenced by interface reaction. With the effect of Coriolis force, the anti-centrifugal turn side is preferentially filled.
