Magnetic measurements of martensitic transformation in austenitic stainless steel after room temperature rolling
Source abstract
Abstract
In order to investigate the detection of martensite phase in deformed austenitic stainless steel, magnetic properties were examined by means of super conducting quantum interface device (SQUID) and vibrating sample magnetometer (VSM) techniques. Stainless steel specimens were rolled at room temperature with 15 to 55% reduction in thickness. Results indicate that the magnetic properties of stainless steel were sensitive to percent reduction in thickness and micro structural condition of stainless steel. It was found that saturation magnetization, amount of martensite and hardness increased whereas, coercive force and remanence ratio decreased with increasing percent reduction in thickness. The saturation magnetization depends mainly on amount of martensite, while the coercive force and remanence depends mostly on shape and distribution of martensite phase.
