温度对TC4/ZL105固液界面组织及显微硬度的影响
Effect of Temperature on Microstructure and Microhardness of TC4/ZL105 Solid Liquid Interface
摘要
Abstract
TC4/ZL105 composites were prepared in a molybdenum wire resistance furnace.The microstructure and constituents of transition layer were characterized by optical microscope (OM),scanning electron microscope (SEM) and energy dispersive spectrometer (EDS),and the microhardness was tested as well.The results show that the TC4/ZL105 bimetallic composites with suitable transition layer can be achieved at 700 ℃ for 60 min with relatively dense microstructure and less defects.In the intermediate layer of the TC4/ZL105 composites,the microstructure is compact near the titanium side,which consists of dense α-Ti solid solution,whereas it is loose on the aluminum side,which is mainly composed of TiAl3 and TiSi2 eutectic phases.In addition,the microhardness on the aluminum side is larger than both of the base metal.The microhardness of the bonding zone also increases with the bonding temperature rising.The peak hardness can reach 643 HV.关键词
