steel research international, Volume 95, Issue 11, November 2024.This article summarizes the literature on metallurgical research using high‐temperature confocal microscopy. In particular, the observation of austenite grain growth is discussed. The effect of alloying elements (solute drag) and that of precipitates at the grain boundaries (pinning) is illustrated based on current results in Fe–P, Fe–Al–N and Fe–C–Nb ...

Developing Ultra‐High Strength Bainitic Steel by Hot Stamping Process and Anisothermal Holding
steel research international, Volume 95, Issue 9, September 2024.This study aims to produce bainitic steel parts after hot stamping/press hardening by using an anisothermal annealing. A bainitic matrix including martensite, fine‐grained ferrite, and retained austenite was obtained and analyzed by characterization techniquies. Different cooling strategies were employed to alter the microstructure to achieve a tensile

Crystal Structure of Acicular Barium Ferrite Fine Particles.
Journal of the Japan Society of Powder and Powder Metallurgy, 1997 Acicular barium ferrite fine particles doped with Co2+ ions and Ti4+ ions were prepared by a conventional sintering method. We investigated fine structure of the acicular BaCoxTixFe12-2xO19 (X=0 and 0.7) particles using x-ray diffractometer (XRD) and high resolution transmission electron microscope (HR-TEM). From x-ray diffraction patterns of them, the

Inclusions in steel coated electrodes welds of car body [PDF]
Transport Problems, 2007 The goal of this project (BK-284/RT1/2007) is to chose the proper method of car body welding. SMAW could be treated as the main method used in the transport industry. Properties of metal weld deposits depend on many conditions.
