## Description

- description: Additive manufacturing of bulk metallic glasses using laser powder
    bed fusion is a challenging task, even for materials with a high glass-forming
    ability. This is due to the complex thermal history of the additively manufactured
    glass-forming materials, which are repeatedly heated upon laser processing of
    subsequent layers, leading to their devitrification. In this study, the influence
    of laser processing on the commercial Cu-based metallic glass AMLOY-CU01, having
    a reduced glass transition temperature Trg ∼0.44, has been systematically explored,
    incorporating high-energy synchrotron X-ray diffraction studies complemented by
    transmission electron microscopy. Despite the low Trg, both vitrified and devitrified
    states can be obtained. The findings reveal that phase composition is weakly correlated
    with porosity in the keyhole regime but shows a strong correlation in the lack
    of fusion regime. The stabilization of the nearly glassy state of the metallic
    glass is achieved within a laser energy density range of 11 J mm−3 ≤ e ≤ 25 J mm−3
    and a normalized enthalpy range of 92 ≤ ΔH ≤ 239, correlating with moderate porosity
    values in the obtained samples. The current results provide insights into the
    fundamental understanding of phase formation in glass-forming materials synthesized
    by laser processing and pave the way for their engineering application.
