## Description

- description: 3D Additive Manufacturing (AM) is a promising processing method that
    enables the fabrication of complex shapes by melting and solidifying one layer
    at a time using a laser or electron beam. Additionally, in the AM process, super
    thermal field could have a significant impact on the microstructure of metallic
    materials and mechanical properties. In this study, the microstructure evolution
    produced by the laser powder bed fusion (LBPF) and subsequent heat treatment of
    near α-Ti (Ti-6Al-4Nb-4Zr, mass%) and near β-Ti alloys (Ti-6Al-2Sn-4Zr-6Mo) was
    investigated. Creep behavior of near α-Ti and near β-Ti alloys was also investigated,
    and the potential of LBPFed Ti alloys as jet engine materials is discussed.
