Development of Nanocrystalline 304L Stainless Steel by Large Strain Cold Working

Relaxation Peaks of Cold Worked 304l Stainless Steel

In this investigation internal friction of cold worked 304L austenitic stainless steel was measured and the new peaks (PlIP2,P3) were found. The height of those peaks increased with cold work degree. The temperature of the main peak P3 was 33513340K at the frequency of -1,000Hz. The activation energies and frequency factors were obtained from peak shift. The values were 0.4evl 0.4evl 0.6ev and ...

Warm Pre-Strain: Strengthening the Metastable 304L Austenitic Stainless Steel without Compromising Its Hydrogen Embrittlement Resistance

Plastic pre-strains were applied to the metastable 304L austenitic stainless steel at both room temperature (20 °C) and higher temperatures (i.e., 50, 80 and 100 °C), and then the hydrogen embrittlement (HE) susceptibility of the steel was evaluated by cathodically hydrogen-charging and tensile testing. The 20 °C pre-strain greatly strengthened the steel, but simultaneously significantly increa...

Strain-Induced Martensite Transformation Simulations during Cold Rolling of AISI 301 Austenitic Stainless Steel

Austenite is a semi-stable phase in most stainless steels that deforms to martensite under Md30 and forms martensitetype ά and ε due to the deformation in the steels. Since the distribution of strain induced martensite plays animportant role in achieving desired properties, the main objective of the present work is to model martensitedistribution of ά during cold rolling using...
