“…Greater abrasive resistance for low bainite matrix, with the same hardness, under a pin-on-disc test has been reported [1]. In recent time, heat treatment of steels with bainite structure ensures a good complex of mechanical properties has been observed [2]. Evidence showed that the ST60Mn steel reliability in these applications in terms of wear characteristic is lower than its imported counterparts [3].…”

Steels are used widely for production of machine components due to their versatility, low cost, ease of production and modification of their properties through heat-treatment. ST60Mn Steel is one of the common high strength steel produced in Nigeria and utilized for machine building purposes. Components made from this materials failed by wear, corrosion or both mechanism. The aim of this paper is to determine the influence of austempering heat-treatment on the corrosion-wear resistance of ST60Mn steel in cassava juice. The heat-treatment was performed by varying the austenitizing temperature, austempering temperature and time. The corrosion wear resistance was investigated under an instrumented pin-on-disc wear testing machine with the steel samples dipped in the cassava juice. The results obtained showed that the austempered ST60Mn steel has a wear rate of 3.0µg/cycle. While, the un-heat-treatment sample possess 70.1µg/cycle. This is a tremendous improvement in corrosion wear rate through the austempering heat treatment.

The constant increase in the requirements for the protection of armored vehicles, caused by the improvement of highly effective weapons, dictates the need to find new approaches to increase the dynamic stability of armor steels using modern metallurgical, materials science and design achievements. The development and design of workable materials and structures of armor protection is a complex scientific and technical problem. The purpose of the work is to determine the promising directions for improving the composition and processing technologies of high-strength steels for the production of heavy-duty rolled steel, which will ensure an increase in the operational characteristics of armor. The work considers the requirements for the physical, mechanical and ballistic characteristics of rolled steel for the production of armored barriers. The influence of alloying on the properties of high-strength steels, which are currently used for the manufacture of armor protection, is analyzed. Modern trends to improve their quality are considered. The types of thermal treatment of thick rolled products, their influence on the formation of the structure and complex of mechanical properties, armor resistance and survivability of elements of special products are analyzed. Based on the results of the research, it was established in the paper that the formation of a structure of finely dispersed bainite ferrite without the release of cementite-type carbides in combination with stable residual austenite is a promising direction for obtaining a high complex of strength and viscosity, as well as ballistic characteristics of structural steels. The formation of such a structure is achieved thanks to the complex alloying of steel with chemical elements that allow to almost completely suppress the processes of carbide formation in bainite ferrite (silicon, aluminum, cobalt, nickel).
