The Synchrotron Radiation for Steel Research

open access: yesAdvances in Materials Science and Engineering, Volume 2016, Issue 1, 2016., 2016
The synchrotron X‐ray radiation is a great tool in materials characterization with several advantageous features. The high intensity allows clear interaction signals and high energy of X‐ray yields higher sampling volume. The samples do not need extra preparation and the microstructure is therefore not affected. With the tunability of the X‐ray energy,

Corrosion of MgO-C with Magnesium Aluminate Spinel Addition in A Steel Casting Simulator

open access: yesCeramics, 2020
For more than 20 years, the sidewalls and bottom of steel ladles have been lined with carbon-bonded magnesia (MgO-C) and magnesia-alumina bricks (MAC). The alumina raw materials react with magnesia forming a spinel, which decreases open porosity and slag
