Liquidus Projection of the Zr-Si-B Ternary System
Source abstract
Abstract
The knowledge of phase equilibria in RM-Si-B systems (RM = Refractory and/or Reactive Metals) is of great interest for the elaboration of thermodynamic databases, aiming the development of high temperature materials. Despite this, no experimental investigation is available in the literature concerning the liquidus projection of the Zr-Si-B system. Based on that, in this work, the liquidus projection of the Zr-Si-B ternary system was experimentally investigated in the Zr-ZrB2-ZrSi2 region via microstructural characterization of arc-melted alloys in the as-cast state using x-ray diffractometry and scanning electron microscopy. A proposal for the Zr-Si-B system liquidus projection is presented for the first time containing eight primary precipitation fields in which the ZrB2 prevails and no signs of a ternary phase was found.
