SOVIET TECHNOLOGY ON THERMAL-MECHANICAL TREATMENT OF METALS

Abstract
One of the most promising methods for strengthening metallic materials that has evolved in the past 15 years is the process of thermal mechanical treatment (TMT). This process, which involves plastic deformation at elevated temperatures and retention of the 'worked' structured at ambient temperature is unique--increases in strength may be attained with a gain or little loss is ductility. There are, of course, definite problems associated with the process such as the degree of temperature control required in plant operations and the negation of the TMT effect in welding processes. This report reviews the trend of Sovient efforts.
