چکیده
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 1 x1013 s-l, 2 xlO'hs', 1.58 x1012 s-l for P1, P2 and P3, respectively. Possible mechanism for the prosses responsible for those peaks are brifly discussed.

Effects of Martensite Reversion Parameters on the Formation of Nano/ultrafine Grain Structure in AISI 304L Stainless Steel
Formation of nano/ultrafine grain structure in AISI 304L austenitic stainless steel through the martensite reversion treatment was studied. The solution annealed specimens were cold rolled up to 95 % thickness reduction at -15°C. The cold-rolled specimens were subjected to reversion annealing treatment at the temperature range of 700-1000 °C for 10–150 min. Microstructural evolutions were analy...

304 stainless steels (SS) were considered as the materials for a dry storage canister. In this study, ER (Electrode Rod) 308L was utilized as the filler metal for the groove and overlay welds of a 304L stainless steel substrate, which was prepared via a gas tungsten arc-welding process in multiple passes. The electron backscatter diffraction (EBSD) map was used to identify the inherent microstr...

The corrosion resistance of type 304L and 316 austenitic stainless steels in 2M H2SO4 at 0-1.5%NaCl concentrations was studied through potentiodynamic polarization technique and optical microscopy analysis. The corrosion rate, pitting potential, passivation potential and surface morphology of both steel where significantly altered by the Clion concentration, alloy composition and metallurgical ...

The cold roll bonding of Al on AISI 304L stainless steel was carried out to fabricate the Al/304L/Al clad sheet composites. The maximum bond strength of 20 N/mm was acquired just by 38% reduction, for which the tearing of the aluminum sheet occurred during the peeling test. The microstructural evolution during subsequent postannealing heat treatment was systematically studied based on the impur...
متن کاملStudy on Oxidation of Stainless Steels During Hot Rolling
The oxidation of stainless steels 304 and 304L during hot rolling is studied in this paper. Results show the oxide scale thickness decreases significantly with an increase of reduction, and the oxide scales of both 304 and 304L stainless steels were found more deformable than the steel substrate. Surface roughness shows a complicated transfer during the hot rolling process due to the complexity...
