Abstract:This research article highlights the application of Infra red thermography (IRT) technique for analyzing the surface temperature variations during the tensile deformation. Few comparative tensile deformation tests were conducted on friction stir welded (FSW) P91-316LN dissimilar joints. The rise in temperature during plastic deformation is monitored under different welding and offset conditions and the deformation behavior
The study of deformation behavior was performed on AISI 316L stainless steel and Ti6Al4V alloy. Six cy-lindrical tensile test specimens with a gauge length of 28 mm and gauge diameter of 5 mm were prepared from swaged bars of both materials supplied by the company MEDIN, a.s. (Czech Republic). The initial microstructure of both alloys was ob- Cr[sub 2]N precipitation stages in 316LN austenitic Sep 01, 1994 · Uniaxial tensile tests were conducted on AISI 316LN austenitic stainless steel from 40 to 300 °C at a rate of 0.5 mm/min. Microstructure and mechanical properties of the deformed steel were investigated by optical, scanning and transmission electron microscopies, x-ray diffraction, and microhardness testing.
Jun 26, 2019 · To prepare austenite stainless steel with high strength and toughness, 90% cryo-rolled 316LN austenitic stainless steel was annealed at temperatures ranging from 600 °C to 900 °C for 10 min. Microstructure and mechanical properties of the annealed samples were investigated by means of optical, scanning and transmission electron microscopy, x-ray diffraction, mini-tensile testing and micro Effect of post-forging heat treatment on stress corrosion Effect of post solution- and stress relief-treatment on the stress corrosion cracking (SCC) resistance via U-bend specimens test in 42% boiling MgCl2 solution, as well as the microstructure, residual strain and mechanical properties of the forged 316LN stainless steel was studied. Results showed that the yield stress was reduced and the residual strain was eliminated through post solution
The heterogeneous mixed-grain microstructure is a common defect for the heavy forging of 316LN austenitic stainless steel. Isothermal compression experiments were performed on a Gleeble3500 thermo-mechanical simulator to investigate the effect of process parameters on the fragment and refinement of millimeter-grade coarse grains (MCGs) during hot cogging. HIGH-TEMPERATURE CHARACTERISTICS OF STAINLESS (Short-time tensile data on eight AISI-numbered stainless steels frequently used for high-temperature service are presented in the tables beginning on page 32.) Creep Over about 900°F (482°C), deformation under stress is plastic rather than elastic, so the yield point as determined by the short-time tensile test is higher than the

Hot Tensile Deformation Behaviors of an AISI 316LN Stainless Steel p.367 Comparison Study on Friction-Welded Cu-Al Material and Pure Cu/Al Materials Free Full-Text A Comparison Study of In this research, hot deformation experiments of 316L stainless steel were carried out at a temperature range of 8001000 °C and strain rate of 2 × 1032 × 101. The flow stress behavior of 316L stainless steel was found to be highly dependent on the strain rate and temperature. After the experimental study, the flow stress was modeled using the Arrhenius-type constitutive equation
The uniaxial tensile test is often used to determine the mechanical properties of a material like its yield strength and elastic limit. However, some of the recent advances in imaging Non Destructive Evaluation (NDE) modalities offer experimental tools which, apart from determining the conventional properties, also make it possible to visualise and map the dynamic strain evolution during Precipitation and hot deformation behavior of austenitic Dec 01, 2017 · Guo et al. concluded that the higher deformation temperature and the lower strain rate would lead to the smaller peak flow stress in 316LN austenitic steel . Dehghan-Manshadi et al. investigated the dynamic and post-dynamic recrystallization processes of AISI 304 austenitic steel, as well as the relationships between these two phenomenon .
