Abstract

The directional solidification of Ni70.2Si29.8 eutectic alloy was carried out, and the solidification microstructure and compression properties of Ni2Si – Ni31Si12 eutectic composite were systematically studied. Directional solidification samples were obtained by induction heating and down – draw process. During directional solidification, well-aligned lamellar structure with a micron scale was obtained in directional solidified Ni70.2Si29.8 eutectic alloy. Despite it is a kind of faceted – faceted eutectic alloys, highly regular and homogeneous structure was obtained through directional solidification. Compared with other methods, the compress test results showed that fracture strength of Ni70.2Si29.8 eutectic alloy obtained through directional solidification was improved obviously, reaching 2100 MPa.
