摘要

The effect of Si content (in the range of 0.01 to 1.91 wt.%) on scale formation on electric steels in air at the temperature ranging from 850 to 1200 °C was investigated. The effect of applied tensile strain on oxidation behavior was also explored. A thermo-mechanical simulator (Gleeble machine) was employed to conduct the oxidation tests at different strain rates. The experimental results showed that at temperature below 1100 °C the oxidation rate decreased with increasing Si content in the steel. The formation of an inner scale, mainly consisting of silica, was responsible for the improved oxidation resistance. However, a substantial increase in oxidation rate due to the formation of molten eutectic fayalite (Fe2Si04) was observed when the temperature was raised to 1200 °C. Under straining conditions and at very short oxidation time, the inner scale structure was slightly modified though the scale thickness remained almost unchanged for the steel containing 1.91 wt% Si.
