Charpy udarna žilavost i tvrdoća odžarenog materijala i donjeg bainita
Metalurgija, 2010 Nisko legirani V-Nb čelik visoke čvrstoće (HSLA) je toplinsko obrađen na martenzit i bainit sa različitom veličinom zrna, odžaren 3 sekunde na 750 °C i ohlađen na zraku. Chapy žilavost je određena u intervalu od -100 °C do 60 °C, a tvrdoća kod sobne temperature.

, 2020 ABSTRACT: Carbo-austempered steels are established as an exciting alternative for the replacement of conventional carburized quenched and tempered (carburized-Q&T) steels, especially in applications demanding high stability and reliability against wear and fatigue (e.g., pinions, gear wheels and power shafts), thanks to the high compressive stresses ...

Transformación bainítica en aleaciones Fe-C
Ingeniería y Ciencia, 2005 Algunas aleaciones Fe-C presentan una excelente combinación de tenacidad y resistencia mecánica, asociada a los productos de la reacción bainítica, que las hace útiles en la fabricación de componentes de máquinas sometidos a altos esfuerzos. Sin embargo,

Mehanizem hitre tvorbe bainita pri nizkih temperaturah
, 2022 A novel procedure for the obtainment of rapid bainite formation within steels was developed. Consequently the new group of steel grades exhitis very rapid bainite formation at low temperatures, commonly below 250°C. These steels develop a very fine bainitic microstructure during continuous cooling/quenching from the austenitization temperature, without

Desgaste por deslizamiento en seco de aceros perlíticos y bainíticos
Dyna, 2004 El desgaste por deslizamiento tiene una gran influencia sobre el desempeño de los sistemas rueda-riel, en particular, por el deslizamiento de la pestaña de la rueda sobre la parte interna del riel en una pista curva.

UTJECAJ KEMIJSKOG SASTAVA I BRZINE OHLAĐIVANJA NA MORFOLOGIJU BAINITA VISOKOČVRSTIH ČELIKA
2016Bainitni čelici sa širokim rasponom ugljika (u području manje od 0, 1 % C do 1 % C) posljednjih su godina u fokusu različitih istraživanja. Značajni rezultati postignuti su u području niskougljičnih bainitnih čelika (TMCP, HSLA), a sve više istraživanja prebacuje se u područje srednje i visoko ugljičnih čelika kod kojih je uz vrlo visoku čvrstoću ...

The 0.1C 0.032Nb fine grained steel was heat treated to fine and coarse grained lower bainite and martensite. Half of specimens was reheated for 3 s at 750 °C with current conduction. Charpy notch tests were performed in temperatr!ure range from -200 °C to 60 °C, room temperature hardness determined and microstructure and fracture surface examined with
