摘要

本工作提出一种倾斜放置籽晶制备镍基单晶高温合金以获得特定取向单晶铸件的方法,采用实验和数值模拟研究该方法制备单晶过程中凝固组织演化过程及其机制,并讨论了倾斜籽晶控制单晶铸件晶体取向的原理。结果表明:通过改变〈001〉取向的籽晶与铸件之间的位向关系,可以制备出特定取向的单晶铸件。单晶制备过程中籽晶部分回熔,回熔界面与籽晶轴向垂直,定向凝固过程中熔体沿未熔籽晶外延生长形成单晶。

Abstract

An inclined seeding method for Ni-based single crystal superalloy with a specific orientation is presented. The evolution of solidification microstructure and its mechanism are studied during the preparation of single crystals by this method through experiment and numerical simulation. The principle of controlling the crystal orientation of single crystal castings by inclined seeding crystals is discussed. The results show that single crystal castings with specific orientations can be produced by changing the orientation relationship between the 〈001〉 orientation seed and the casting. During the preparation process of single crystal, the seed is partially un-melted, and the un-melted interface is perpendicular to the seed axial. The melting alloy grows epitaxially along the un-melted seed to form a single crystal casting during the directional solidification process.
