stainless steel) were characterized after hot deformation. The electronic structure and phase stability of titanium carbosulde were further discussed by rst-principle calculations. It was found that Y phases, like curved strips or bones in AISI 321 stainless steel, mostly show a clustered distribution and are approximately arranged in parallel. Characterization and mechanical behavior of AISI 316L Jul 01, 2020 · According to the yield and tensile strength of the base metals, the AISI 316 L showed a lower strength compared to Incoloy 825. As it can be seen, strength of the weldments was not inferior to the weaker parent metal (i.e. AISI 316 L), suggesting that sound welds could be obtained by setting the welding parameters reported in Table 2. The elongation of the weldments was found to be in a range

Effect of hot forging on the slurry erosion wear of

Jan 01, 2020 · Hot forged samples at 950 0 c show the maximum erosion resistance due increased hardness of the surfaces. Due to hot forging of as received materials at 950 0 c, erosion resistance increases by 42.11% and 46.54% for SS316 and SS410 respectively.

Hot Deformation and Recrystallization Mechanisms in a Jan 08, 2019 · The hot deformation behavior and associated microstructural evolution of a coarse-grained Nb-bearing austenitic stainless steel (316Nb) has been investigated by the means of torsion tests at high temperature [1223 K to 1423 K (950 °C to 1150 °C)] followed by microstructural characterization. The starting microstructure was varied by applying prior annealing. Llanos, L., Pereda, B., Lopez, B. and Rodriguez-Ibabe, J.M Llanos, L., Pereda, B., Lopez, B. and Rodriguez-Ibabe, J.M.

Along with the increase in the SFE, steels are very susceptible to hot cracking during hot deformation, especially edge cracking due to the Microstructure and Mechanical Characterization of Friction Dec 17, 2018 · Fusion welding of austenitic stainless steels (ASSs) causes undesirable metallographic changes. An attempt has been made to join 3-mm-thick 316L ASS plates using friction stir welding and correlate the microstructural evolution and the mechanical properties under various welding conditions. Tungsten alloy (W-Re) tool was employed for welding. Successful joints were obtained within a range

Aug 01, 2012 · A numerical model has been formulated for hot deformation during friction assisted additive manufacturing of interlayer buttons which ease the transition from P91 to AISI304 using interlayer Inconel alloys with intermediate coefficients of thermal expansion. Nitriding Process Characterization of Cold Worked AISI 304

  • AbstractIntroductionMaterials and MethodsResults and DiscussionConclusionsAcknowledgmentsThe nitriding behavior of austenitic stainless steels (AISI 304 and 316) was studied by different cold work degree (0% (after heat treated), 10%, 20%, 30%, and 40%) before nitride processing. The microstructure, layer thickness, hardness, and chemical microcomposition were evaluated employing optical microscopy, Vickers hardness, and scanning electron microscopy techniques (WDS microanalysis). The initial cold work (previous plastic deformations) in both AISI 304 and 306 austenitic Enhanced Wear Resistance of 316 L Stainless Steel with a Abstract:The low hardness and poor wear resistance of AISI 316 L austenitic stainless-steel sabotage its outer appearance and shorten its service life when it is subjected to sliding. In this paper, the single-pass ultrasonic surface rolling (USR) process was used to modify the surface of 316 L IJMME Vol 17 Issue 02 - IJENSAbstract:Austenitic stainless steel types AISI304 and AISI316 are material characterised by their high ductility and toughness. In this paper, the deformation characteristics of AISI316 and AISI304 stainless steel are investigated in a temperature range of 850-1050 °C and strain rate range of 0.001-0.1 s-1 using dilatometer hot compression tests.
