A Fundamental Investigation into Particle Size and Shape Control During SHS Reactions

本文的重点是建立一个基于反应的模型来预测等离子体引发的自蔓延高温合成(PSHS)工艺参数，以控制所得到的细颗粒的颗粒形状、尺寸形貌等性质。提出的工作包括实验和建模两个部分。提出要研究的两个系统，包括金属间化合物Ni-Al和Ti-Al。将对所得到的粉末进行现场m和详细的微观结构表征。

ABSTRACT -- III-9362183 Guha The focus of this proposal is to develop a reaction based model which predicts Plasma Initiated Self Propagating High Temperature Synthesis (PSHS) process parameters in order to control such properties as particle shape, size morphology etc. of the resulting fine particles. The proposed work includes both an experimental and modeling components. Two systems are proposed to be investigated and include the intermetallics Ni-Al and Ti-Al. In-situ m and detailed micro structural characterization of the resulting powders will be carried out.
