## Description

- description: 'The layer-by-layer laser powder bed fusion (L-PBF) process was applied
    to fabricate functionally graded multi-materials (FGMs) of nickel-titanium alloy.
    The FGMs Ni-Ti alloy was built with composition transitioning from pure Ni incrementally
    graded to pure Ti by different composition gradients. The microstructure, chemical
    composition, and phase evolution were characterized using SEM, EDS, XRD, and EBSD
    along the build direction. By varying the proportions of Ni and Ti, the microstructure
    and phases were changed gradually across the build direction. Several phase transformations,
    gamma-Ni -> NiTi B2 + intermetallic phases alpha-Ti, appeared through the compositional
    gradient. Cracks were found in the gradient zone, and the results were explained
    in terms of the various phases present. The potential to accomplish such a completely
    deposited FGMs Ni-Ti alloy and considerable changes in composition are made possible
    by a new strategy to make innovative FGMs Ni-Ti alloys together with 3D components
    using L-PBF additive manufacturing. '
