Possibility as a magnetic recording media of austenitic stainless steel using stress-induced phase transformation

Hardening Optimization of High Chromium-manganese Austenitic Steel

“…[10][11][12] The observed flow stresses of the studied steel during the tensile tests performed above the room temperature are featured by a decreasing trend as the temperature increases, but above 350°C also the overall elongation at the fracture point decreases as temperature increases. The specimens strained at 500°C is affected by a significant loss of ductility.…”

Out-of-plane magnetic patterning on austenitic stainless steels using plasma nitriding

“…[10][11][12] Nevertheless, relatively little is known about the magnetic properties of the expanded austenite. Both mechanical 13,14 and ion beam nitriding 15 have been exploited to locally generate ferromagnetic structures on ASSs ͑i.e., magnetic patterning͒. However, only in-plane magnetization has been demonstrated up-to-date in these magnetic patterning methods.…”

Selective generation of local ferromagnetism in austenitic stainless steel using nanoindentation

“…5,6 At room temperature, the austenite phase is paramagnetic, while it becomes antiferromagnetic below its Néel temperature, which is about 40 K. 7 Conversely, the stressinduced martensite phase is ferromagnetic, as it has been demonstrated by a number of different techniques. [8][9][10][11][12] Actually, these properties are being exploited to develop novel nondestructive methods, using magnetic measurements, to evaluate the degradation of austenitic steel. [13][14][15] However, in some cases, the formation of martensite is desirable.…”
