DEVELOPMENT OF CASTED MACROHETEROGENEOUS COMPOSITE MATERIALS WITH THE FRAGMENTATION OF REINFORCING ELEMENTS

摘要

The development of controlled structures in macroheterogeneous composite materials applying the fragmentation of reinforcing elements has been presented. The influence of the synthesis temperature and the duration of the keeping at this temperature on the structure resulted has been shown. It has been established that the materials of reinforcing elements and matrix alloy have a strong influence on composite structures. The combination of parameters mentioned above provides the formation of a wide range of solidified structures: from the structure of common alloys to pseudoalloys ones. Thus the fragmentation of reinforcing particles in macroheterogeneous composites allows controlling structures and consequently mechanical properties according to working requirements.
