TC4钛合金电子束熔丝沉积快速成形性能研究

Performance of Titanium Alloy Electron Beam Fuse Deposition Rapid Prototyping

  • 摘要: 采用熔丝沉积的方法进行电子束增材制造是一种新兴的快速制造技术,可以用于医疗、航空与航天等领域金属结构件的制造。试验过程旨在找出电子束熔丝沉积快速成形过程对TC4钛合金的显微组织以及显微硬度的影响。结果表明:添加椭圆扫描波形使电子束的作用范围增加,并且能量分布更加均匀;在加工后的熔融区以及相邻的熔覆区均发现了一定体积分数的α相和α'相,在快速成形过程中熔融区和熔覆区均经历了由初生α→β→α/α'的相转变过程。

     

    Abstract: Electron beam fused deposition rapid prototyping is a new kind of rapid prototyping technology, can be used for manufacturing of large metal structures, aerospace, medical and other fields. During the inspection of electron beam in order to find out the fused deposition forming process on Microstructure of TC4 titanium alloy and influence of micro-hardness. The results show that the effect range of the electron beam is increased and the energy distribution is more uniform; A certain volume fraction of α phase and α' phase have been found in the melt zone and adjacent zone, In the process of rapid prototyping, the melting zone and the cladding region have experienced the phase transition process from primary α→β→α/α'.
