Effect of Thermal History on the Deformation of Non-metallic Inclusions During Plain Strain Compression

Effect of Thermal History on the Deformation of Non-metallic Inclusions During Plain Strain Compression

The deformation of inclusions in the steel was affected by the thermal history during the physical simulation of steel processing. After plain strain compression with a reduction of 30 pct, the average aspect ratio of inclusions in the steel sample cooled down to 1673 K from semi-solid state was 1.8...

Zusammenfassung:The deformation of inclusions in the steel was affected by the thermal history during the physical simulation of steel processing. After plain strain compression with a reduction of 30 pct, the average aspect ratio of inclusions in the steel sample cooled down to 1673 K from semi-solid state was 1.89, which was significantly higher than 1.29 in the steel sample heated persistently up to the same temperature. The mechanism was revealed by inclusion transformation.
