This Small Business Innovation Research (SBIR) Phase II project will develop a new ceramic material, yttrium-aluminum garnet (YAG), for cutting tools used in the machining of titanium (Ti) alloys. Phase I found it feasible to base a cutting tool on YAG, reinforced with silicon carbide (SiC) whiskers and TiC. Phase II will further explore the use of YAG-based composites as a cutting tool for Ti alloys through: 1) optimization of compositions and fabrication parameters to obtain a fully dense composite with uniformly dispersed reinforcement phases; 2) evaluate the optimized composite relative to state-of-the-art materials in machining Ti alloys; and 3) identify wear and failure mechanisms by detailed microstructural characterization of YAG-based composite cutting tools, before and after machining tests.Potential commercial applications are expected in titanium-alloy machining operations in the aircraft and aerospace industries.

该小型企业创新研究（SBIR）第二阶段项目将开发一种新的陶瓷材料钇铝石榴石（YAG），用于钛（Ti）合金加工中使用的刀具。 第一阶段发现它是可行的基础上YAG，增强碳化硅（SiC）晶须和TiC的切削刀具。 第二阶段将进一步探索YAG基复合材料作为钛合金切削工具的用途，具体做法是：1）优化成分和制造参数，以获得具有均匀分散的增强相的完全致密的复合材料; 2）评价优化后的复合材料相对于加工钛合金的最新材料的性能; 3）通过YAG基复合材料刀具的详细微观结构表征来识别磨损和失效机制，在飞机和航空航天工业的钛合金加工操作中，预期潜在的商业应用。
