Investigation of the reaction zone structure under mechanochemical synthesis of metal disilicides by a method of local diffractometry

The structure of layers of treatment material on milling bodies in processes of mechanochemical synthesis of metal silicides are investigated. Samples of metallographic specimen of layer on sphere are scanned with step 50 μm. The thickness of layer is 150–250 μm. The layer consists of plastic component (metal) of mix initial products and compound appearing in result of mechanochemical reaction. The less plastic component (silicon) not detected in layers. Two types of distribution of phases in layers on milling sphere are revealed.
