Small Punch Tests at Oxide Scales Surface of Structural Steel and Low Silicon Steel

This work is focused on the study of the behavior of oxide scale layers grown on two types of steel: plain carbon steel and silicon-alloyed steel. The small punch test method was chosen to study the mechanical properties of oxide scale layers. Several specimens were prepared from both materials and exposed to 1,000 A degrees C for different oxidation times to obtain the desired scale layers. When the oxidation process was complete, oxide layers of varying thickness, composed mainly of hematite and magnetite, were created. The specimens were used for testing at temperatures between 600 and 900 A degrees C.
