Atom Probe Tomography Analysis of Precipitation during Tempering of a Nanostructured Bainitic Steel

, 2013
Carbon distribution during tempering of a nanostructured bainitic steel was analyzed by atom probe tomography (APT). Three different types of particles are detected on samples tempered at 673 K (400 °C) for 30 minutes: lower bainite cementite with a ...

Tensile behaviour of a nanocrystalline bainitic steel containing 3 wt% silicon

, 2012
Much recent work has been devoted to characterize the microstructure and mechanical properties bainitic nanostructured steels. The microstructure is developed by isothermal heat treatment at temperatures as low as 125–350 °C and adapted steel grades ...

Microstructure and mechanical response of nanostructured bainitic steels

, 2016
Nanostructured bainite is a promising new steel concept presenting excellent values of rivalling mechanical properties, strength vs. toughness or ductility. These microstructures, as opposed to conventional bainite, contain retained austenite. This, together with the fact that the structure is refined down to the nanoscale, are responsible for the good

An Artificial Neural Network Model to Predict the Bainite Plate Thickness of Nanostructured Bainitic Steels Using an Efficient Network-Learning Algorithm

, 2018
Nanostructured bainitic steel has an extraordinary ultrahigh strength of about 2.0 GPa along with good toughness of 30 MPa m1/2. The finer thickness of plate 20-80 nm is largely responsible for achieving such a large hardness of 690-720 HV. In this work,
