Abstract
SHS investigation development is considered from the geographical and historical viewpoint. 3 stages are described. Within Stage 1 the work was carried out in the Department of the Institute of Chemical Physics in Chernogolovka where the scientific discovery had been made. At Stage 2 the interest to SHS arose in different cities and towns of the former USSR. Within Stage 3 SHS entered the international scene. Now SHS processes and products are being studied in more than 50 countries.
Abstract
Steel castings are chosen for several wear conditions as elements of machines working in mining, transport and military industries. They work mainly in contact with ceramic materials (quartz sands, different ores, water-solid particles). In general, castings work with abrasion condition with high stresses. This chapter shows the types of wear, effect of hardness, load, and temperatures on weight losses. In the present work, the microstructure of used grades, their heat treatment and mechanical properties are shown.
Keywords:
