Influence of technological parameters in SHS-compacting on composition, structure and properties of functional gradient targets based on TiB2 and TiN

Microstructure is studied and diagrams of micro-hardness of 3-layer targets are built depending on the mass of the chemical furnace; these diagrams allow forecasting properties of products. The mass of layer of the chemical furnace which is optimal with respect to other layers of charge is found. Regularities of phase and structure formation are established for 2- and 3-layer products of synthesis with working layer based on TiN-TiB2. Varying the mass of the chemical furnace gives an essential effect of grain enlargement for presented phases, owing to increase of time for secondary structure formation
