采用10×10網(wǎng)格蠟網(wǎng)制備熔模鑄造型殼，研究型殼預(yù)熱溫度、離心轉(zhuǎn)速以及型殼面層材料對IMI834高溫鈦合金充型能力的影響。
IMI834高溫鈦合金熔模鑄造充型性能Investment casting mold filling capacity of high temperature titanium alloy IMI834采用10×10網(wǎng)格蠟網(wǎng)制備熔模鑄造型殼，研究型殼預(yù)熱溫度、離心轉(zhuǎn)速以及型殼面層材料對IMI834高溫鈦合金充型能力的影響。研究結(jié)果表明：在本實(shí)驗(yàn)條件下，當(dāng)型殼預(yù)熱溫度為400~600 ℃，離心轉(zhuǎn)速為300 r/min時，IMI834的充型性能最好。面層材料以CaO穩(wěn)定的ZrO2和醋酸鋯粘結(jié)劑制備的型殼充型性能遠(yuǎn)好于Al2O3和硅溶膠粘結(jié)劑制備的型殼的，表明界面反應(yīng)對合金的充填性能有極大的影響。離心澆注實(shí)驗(yàn)結(jié)果表明：合金熔體在Coriolis力的作用下優(yōu)先向與離心轉(zhuǎn)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.
