Effect of Stepwise Cooling on the Microstructure and Mechanical Properties of a 1300 MPa‐Grade High‐Strength Steel for Engineering Machinery

This study investigated a 1300 MPa‐grade engineering‐machinery steel processed by four stepwise cooling routes with intermediate cooling temperatures of 800 or 850 °C and final cooling transition temperatures of 500 or 650 °C. The cooling route markedly affected the bainite/marte...

A Chromium‐Free Fe‐Added MgO–SiC–C Refractory With Superior Dynamic Matte Slag Corrosion Resistance

ABSTRACT To develop a chromium‐free alternative to MgO–Cr 2 O 3 refractories for matte smelting furnaces, this study investigated three novel MgO–SiC–C refractories (with Fe, Si 3 N 4 , or Si 3 N 4 –Fe additions) via induction furnace tests simulating actual smelting. Results sho...
