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.

摘要-- III-9362183 Guha 该建议的重点是开发一种基于反应的模型，该模型预测等离子体引发的自膨胀高温合成（PSHS）工艺参数，以控制所得细颗粒的颗粒形状、尺寸形态等性质。 拟议的工作包括实验和建模组件。 两个系统被建议进行研究，包括金属间化合物Ni-Al和Ti-Al。原位m和详细的微观结构表征所产生的粉末将进行。
