Current Trends to Obtain Metals and Alloys with Ultrafine-Grained Structure

Abstract

production of ultrafine-grained materials. however, the growth in demand is significantly limited by the high cost of manufacturing products from such materials due to the high energy and labour intensity of their production. therefore, this article reviews and analyses contemporary technologies for production of metals and alloys with the ultrafine-grained structure, combining both high strength and ductility, by using the relatively simple and inexpensive devices, which allow spending the minimum possible amount of time in the manufacture of products. the literature overview shows the level of the process to develop technology for obtaining the ultrafine-grained structure in metals and alloys. Such the structures provide a combination of a high level of strength characteristics with high ductility that fundamentally distinguishes such the materials from the conventional ones. this is urgent for applications, where the weight, size or special exploitation properties of the part are crucially important.
