Abstract: Installed glass filler and the carbon impact of a particle size less than 50 microns Hardness HRB-metal material on the basis of reduced carbonyl iron powder, ВК-1. With the help of mathematical methods of planning it was developed full factorial experiment on the plan 22. The factors that affect the hardness of HRB materials were adopted: carbon content and the concentration of the glass filler. A regression model predictive value of hardness. Analysis showed that the carbon content of glass powder and increase the hardness HRB-metal material. Effect on hardness of HRB carbon-metal material higher than the glass powder. The materials obtained have a heterogeneous microstructure consisting of a matrix metal and fused glass filler particles surrounded by a transition zone from fayalit. Received various metal matrix structure: ferrite; ferrite + pearlite (~ 50: 50%), perlite (100%). The carbon content in the sintered-metal materials provide the technology.

Key words: powder metallurgy, metal-glass materials, hardness, structure and properties of powder materials.
