Low-Alloyed Spring Steel: Nanostructure and Strength After Austempering

Metals
Carbide-free bainite microstructures were developed in 0.6 wt.%–2 wt.% Si spring steel via austempering at 250 °C. Heat treatment included austenization with subsequent isothermal holding at 250 °C, varying the holding duration to 1.0, 1.5, or 2.0 h with

Compositional design of high strength nanostructured bainite

Materials Research Express, 2018
Strength of carbide-free bainitic steels primarily depends on the thickness of bainitic ferrite and its volume fraction in the microstructure. The morphology and volume fraction of phases formed in bainitic transformation are governed by the steel's composition and transformation temperature.

Effect of metastable retained austenite on dynamic mechanical properties of nanostructured bainitic steel under high-strain rate deformation

Journal of Materials Research and Technology
In this study, modifying the austenitizing temperature offers a strategically viable way towards creating blocky retained austenite (BRA) with varying sizes and morphologies in nanostructured bainitic steel, in strikingly contrast to the conventional ...

Improvement of Strength-Toughness Combination in Nanostructured Bainite

Procedia Structural Integrity, 2018
Abstract The present study makes an effort to improve strength-toughness combination of a high carbon carbide free nanostructured bainite by investigating the effect of content, size and morphology of constituent phases when austempered at 250-350°C.

Wear of fine pearlite, nanostructured bainite and martensite

, 2017
Abrasion is a form of wear prominent particularly in the agricultural, mining, mineral and transportation industries. The cost of abrasive wear to the national economy is estimated to be about 1% of the gross national product, and it can compromise the safety and reliability of engineering components.
