## Description

- description: Hard magnetic materials are classified among functional materials,
    which, in many respects, are the basis of modern technological processes, day-to-day
    operation devices, electrical transport, etc. The rate of improvement of the magnetic
    hysteretic properties of permanent magnets has steadily decreased because in the
    industrial production, the potential of the Nd2Fe14Bcompound has been realized
    almost completely. To further improve the functional properties of articles with
    permanent magnets, new approaches to designing such articles should be used. The
    additive manufacturing of functional magnetic materials and articles based on
    them is among these approaches. Additive technologies have several significant
    advantages over subtractive (edge cutting machining) and forming (strain without
    moving off a material) technologies. One of the advantages consists in the possibility
    of preparing samples and articles of any form, which is limited by the mechanical
    properties of a material. The other advantage is the local tuning of the material
    properties at the preparation stage at the expense of varying both the chemical
    composition and micro-structural state.In the present study, the effect of synthesis
    parameters on the phase composition and magnetic hysteretic properties of single-layer
    Nd2Fe14B-based permanent magnets synthesized by selective laser sintering is investigated.
    The causes for the effect of synthesis parameters on the magnetic hysteretic properties
    are considered. The possibility of reaching a coercivity of single-layer magnets
    of 19.5 kOe, which are free of heavy rare-earth metals, will be demonstrated.Also,
    this work presents a proof-of-concept of additive manufacturing of (Sm,Zr)Fe11Ti
    permanent magnet. A way to produce permanent magnets from (Sm,Zr)Fe11Ti powder
    and its mixture with low-melting additive Sm75(Cu, Co)25 by the selective laser
    melting will be demonstrated. The phase transformations which accompany the liquid
    phase sintering of hard magnetic particles in low-melting Sm75(Cu,Co)25 additive
    will be discussed. The printing parameters which allow sintering of the hard magnetic
    alloy particles were found. When the main phase is (Sm,Zr) Fe11Ti, the coercivity
    of Hc = 5 kOe is achieved. This work was financially supported by FEUZ-2024-0066.
