Long‐Range Ordered Structure of Ti – B – C – N in a TiB ₂ – TiC _x N _{1− x} Eutectic Composite

Abstract

A TiB 2 – TiC x N 1− x quasi‐binary eutectic composite, with a rod‐like faceted texture and a long‐range ordered structure of Ti – B – C – N , was prepared by the arc‐melting of TiB 2 , TiC , and TiN powders. Hexagonal single‐crystalline TiC x N 1− x rods were grown in a single‐crystalline TiB 2 matrix with a crystal orientation relationship of TiB 2 // TiC x N 1− x and TiB 2 [0001] // TiC x N 1− x [111]. A long‐range ordered structure of Ti – B – C – N was formed by the intermixing of the coherent interplanar spacings of seven TiB 2 (0001) and nine TiC x N 1− x (111) planes.
