Abstract

Additive manufacturing is a perspective method to create new functional materials, e.g., permanent magnets. 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 is demonstrated. The phase transformations which accompany the liquid phase sintering of hard magnetic particles in low-melting Sm75(Cu,Co)25 additive are discussed. The printing parameters which allow sintering of the hard magnetic alloy particles are found. When the main phase is (Sm,Zr)Fe11Ti, the coercivity of Hc = 3.0 kOe is achieved.
