摘要:
增材制造技术（也称3D打印技术）在发展新型TiAl合金领域有巨大潜力。电子束熔炼技术制备TiAl合金逐渐引起关注，本文对相关工艺探索的研究进行了综述。通过调节EBM过程中的各工艺参数，例如片层厚度、熔炼温度、扫描速率、线能量和构建路径等参数，可获得致密并且无大量Al损失的均匀样品。经过热等静压处理和热处理，可得到细小均匀的组织。通过控制热处理温度，可获得等轴晶组织、双态组织（片层比率不同）或全片层组织。总结了EBM技术的优点和存在问题，并对其发展前景进行了展望。
Abstract:
Additive manufacturing (3D printing) holds strong potential for the production of a new class of TiAl alloys. In the present paper, recent research progress on the processing TiAl alloys by electron beam melting was reviewed. The EBM parameters such as layer thickness, melting temperature, scanning speed, line energy, or building strategy were set up to minimize porosity and achieve a homogeneous specimen with less Al loss. The very fine microstructure resulting after EBM can be then set up by HIP and heat treatment(HT). According to the HT temperature in particular, an equiaxed microstructure, a duplex microstructure with different lamellar radio and a fully lamellar microstructure were obtained. Summary remarks were presented on the advantageous aspects of EBM and the prospect of this technique also.
