摘要
基于组织定量分析技术,研究了铸型材料和铸板厚度对Ti-6Al-4V钛合金成形性能及成形后铸板的微观组织中原始β晶粒尺寸和α片层间距的影响。结果表明,铸型材料和铸板厚度对Ti-6Al-4V钛合金的成形和成形后的微观组织具有重要影响。石墨铸型相比陶瓷铸型具有较差的成形能力,铸件的微观组织也明显细化。随着铸板厚度的增加,原始β晶粒尺寸、α片层间距呈近线性上升的趋势。
Through quantitative metallographic analysis,effects of mould materials and plate thickness on formability of the TC4 alloy and β-phase grain size and α phase lamellar spacing in microstructure were investigated. The results show that the formation of TC4 alloy and its microstructure are closely related with mould materials and plate thickness. The ceramic mould is superior to graphic mould in formability and in refining microstructure of plate. With increasing in plate thickness,initial β-phase grain size and α phase lamellar spacing are increased in linear way.
