摘要

钛合金铸造模具的获取问题还没有完全解决。这主要是由于钛合金的高反应性导致它们与耐火材料相互作用。由于各种缺陷的形成，这降低了铸件的质量。研究了液态VT1-0级钛与CaO、ZrO2和CaZrO3的相互作用。本文描述了在这些物质之间的接触边界发生的过程以及在该边界附近钛铸件的组织和显微硬度的变化。得到的数据显示了基于CaO和CaZrO3的成型材料的缺点。钛熔体与CaZrO3相互作用的特征，在反应区形成了一个高度多孔的CaTiO3层，使这种化合物有可能被推荐为铸造模具的有前途的材料，以便从钛合金生产铸件。

Investigation of the mechanism for interaction of calcium zirconate, oxides of calcium and zirconium with titanium melts

ABSTRACT The problem to obtain casting molds for titanium alloys is not resolved in full. It is primarily due to the high reactivity of titanium alloys resulting in their interaction with refractory materials. This reduces the quality of the castings due to the formation of various defects. The interaction of VT1-0 grade titanium in the liquid state with CaO, ZrO2 and CaZrO3 were studied. The processes occurring at the contact boundary between these substances and a change in the structure and microhardness of titanium castings near this boundary were described herein. The data obtained showed the disadvantages of molding materials based on CaO and CaZrO3. The features revealed for the interaction of a titanium melt with CaZrO3, where a highly porous CaTiO3 layer has been formed in the reaction zone,made it possible to recommend this compound as a promising material to cast molds in order to produce castings from titanium alloys.

期刊介绍： The International Journal of Cast Metals Research is devoted to the dissemination of peer reviewed information on the science and engineering of cast metals, solidification and casting processes. Assured production of high integrity castings requires an integrated approach that optimises casting, mould and gating design; mould materials and binders; alloy composition and microstructure; metal melting, modification and handling; dimensional control; and finishing and post-treatment of the casting. The Journal reports advances in both the fundamental science and materials and production engineering contributing to the successful manufacture of fit for purpose castings.
