Лично Вам, ин-инглиш - публикация мохнатого года. According a published industrial general inquiry of the institution for ferrous metallurgy the RWTH Aachen by steel producing and - processing enterprises in the German speaking area already 46 % of the end consumers put to use the thermo mechanical treatment (TMT). Out of mechanical engineering - and reinforcing steels, also spring steels were named. The most to converting steels will be reshaped in the region of the stable austenite above of A3 with recrystallization of the austenite before the phase transition. So in consequence of a detailed interpretation of literature about the TMT of spring steels of the Max-Planck-Institute for Iron and Steel Research in Düsseldorf, Germany, leaf springs were produced in the sixties in the USA after the so-called "modified ausforming" (MAF)-treatment and in the Eastern Europe with thermo-mechanical treatment by high temperatures (HTMT). The Japanese spring producer HORIKIRI manufacture the parabolic spring leaves for the so-called TUFLEX-spring, a lightweight spring with about 25 % weight saving by excellent survival probability on an industrial plant with the MAF-treatment. Aim of the first time introduced TMT of spring steel wire in the course of the continuous heat treatment is the engagement of a very fine grained martensitic structure, whereby the spring steel wire also at high tensile strength and yield point receive a high toughness and thereby a high deformation ability.
