Description
It is shown that the combination of the cold equal channel pressing with low-temperature annealing leads to the formation of a sub-microcrystalline ferritic matrix hardened with nanoscale particles of the carbide phase in steel 09G2S. Resulting structure leads to the achievement of the high-strength state, as well as a significant reduction of the wear intensity of the material

Description
Ensuring sustainable development of territories and minimizing damages from the possible occurrence of natural and technogenic emergencies, especially those sparsely populated as the Republic of Sakha (Yakutia), requires the use of GIS technologies. For this purpose developed geospatial data base structure (GDB) which allows solving problems of monitoring and providing safe exploitation of potentially dangerous objects. Furthermore in the process of solving problems GDB takes into account natural hazards, assessment of technical condition of potentially dangerous objects and anthropogenic impacts on the environment

FRACTOGRAPHY OF OPERATION FAILURE OF THE LITING GEAR OF BULLDOZER
Description
The nature and causes of operational failure of the all-metal hydraulic cylinder rod of a bulldozer were studied. It is shown that the main mechanism of failure was evolving in time metal fatigue, initiated by defects of the heat treatment for chromizing
