Effect of Deformation on Microstructure of 301L Stainless Apr 25, 2021 · The chemical composition of 301L stainless steel is shown in Table 1. The forged specimens were hot rolled at 1150°C for 20 min to the thickness of 1.5 mm. The hot rolled specimens were then cold rolled to sheets with a reduction rate of 20 and 40%. The microstructure of 301L stainless steel was examined by optical microscopy, XRD analysis Influence of Size on the Microstructure and Mechanical Jan 29, 2015 · 304L stainless steel in two presentations, bulk and fibers, were systematically studied in order to establish the relationship among microstructure, mechanical properties, manufacturing process and effect on sample size. The microstructure was analyzed by XRD, SEM and TEM techniques.
Jan 29, 2015 · In this work tensile, microhardness and nanoindentation tests were done on a 304L stainless steel in the form of bulk and fibers, in order to evaluate and compare the influence of the microstructure on their mechanical properties. Both presentations showed a similar microstructure and tensile fracture morphology. Mechanical Properties of 304L and 316L Austenitic austenitic stainless steels, two fully austenitic alloys (i.e., type 304L and 316L alloys) have been aged at 290400°C for 1500 hours and characterized. This report will describe the mechanical property changes in 304L and 316L austenitic stainless steels due to the shortest term (1500 h) thermal aging. Microstructural Evolution and Mechanical Properties of Feb 02, 2013 · microstructure of semi-solid processed 304L SS, it is difficult to conclude that the disappearance has occurred during melting as the micrographs have been taken after solidification of the molten fraction. The microstructure of the water-quenched samples after partial melting is shown in Figure3, in which the liquefied
Jan 27, 2021 · Abstract. In the present study, composite bimetallic plates of 10CrNi3MoV steel304L stainless steel were butt welded by shielded metal arc welding (SMAW). A transition layer was designed to compensate for the dilution of Cr and Ni in stainless steel layer during the welding of dissimilar metals. From the results, it was seen that the lowest hardness of fusion weld was located in transition layer, followed by 304L stainless steel Microstructures and Hardness Properties of Stainless Steel Dec 13, 2019 · Stainless steel is the type of steel that is the most commonly used one in the manufacturing of medical devices. Stainless steel 304 from the 300 series of the Austenite grade of stainless steel is used for making medical devices that are used in all types of medical applications. It is the most common type of stainless steel used in the world. Stainless Steel Family|Crystal Structure|Microstructure Austenitic stainless steel Figure 4:Austenitic microstructure showing equiaxed grains and characteristic annealing twins. The normal presence of small inclusions can also be seen. The austenitic grades (see Figure 4) are the largest group of stainless steels, and can be divided into five sub-groups:Cr-Mn grades; Cr-Ni grades, Cr-Ni-Mo grades
