9315057 Bhaduri The ultimate objective of the proposal is to produce zirconia toughened titanium diboride matrix composites by the novel "Combustion Synthesis" or "High Temperature Self Propagating Synthesis" route. The project seeks to achieve one step densification by carrying out carefully planned experiments incorporating transformable zirconia in elemental blends of powders. Zirconia plays two important roles; 1) control the exothermic reaction, 2) impart enhanced toughness to the brittle titanium diboride matrix by the process of transformation toughening. Thermodynamic analyses will also be carried out in order to analyze the effect of the addition of zirconia. %%% The aim of the proposed research is to produce toughened titanium diboride matrix composite materials to retain the beneficial hardness properties of titanium diboride while reducing its brittleness and increasing numerous applications such as coatings for cutting tools will benefit from the research proposed. ***

9315057 Bhaduri 该提案的最终目标是通过新颖的“燃烧合成”或“高温自蔓延合成”路线生产氧化锆增韧二硼化钛基复合材料。 该项目旨在通过进行精心策划的实验，将可转变氧化锆纳入粉末元素混合物中，实现一步致密化。 氧化锆起着两个重要作用： 1）控制放热反应，2）通过相变增韧过程赋予脆性二硼化钛基体增强韧性。 还将进行热力学分析，以分析添加氧化锆的效果。 %%% 拟议研究的目的是生产增韧二硼化钛基复合材料，以保留二硼化钛有益的硬度特性，同时降低其脆性，并增加许多应用，例如切削工具涂层，将受益于拟议的研究。 ***
