The microstructural evolution and impact toughness of

Oct 05, 2016 · The present study focused on the microstructural evolution and impact toughness of NZ in FSWing X100 pipeline steel at rotation speed of 600 rpm and welding speed of 50 mm/min using W-Re stir tool. From this study, the following conclusions are derived: Investigation on Microstructure and Impact Toughness of Nov 22, 2016 · This paper investigated on microstructure and impact toughness of different zones in duplex stainless steel welding joint. High-temperature heat-affected zone (HTHAZ) contained coarse ferrite grains and secondary precipitates such as secondary austenite, Cr 2 N, and sigma. Intergranular secondary austenite was prone to precipitation in low-temperature heat-affected zone (LTHAZ). Dissimilar Friction Stir Butt Welding of AA6061-T6 and Dec 08, 2018 · Impact response of dissimilar friction stir welded (FSWed) joints between a monolithic alloy and metal matrix composite has not been yet reported and thus requires a detailed investigation. Therefore, an exhaustive research on the microstructure, microhardness, tensile properties, fracture toughness and failure response under transverse impact of the FSWed AA6061-T6/AA6061 + SiCp Microstructural Transformations of Dissimilar Austenite This research studies the metallurgical transformations happening during the SMAW welding of AISI 316L austenitic stainless steel with AISI 430 ferritic stainless steel. Two different electrodes, AWS E309L austenitic and AWS E2209-16 duplex stainless steels 3.2 mm diameter, were used to perform the study. The joining was made with a single pass welding and keeping a low heat input ranging from Effect of Nickel Content on the Microstructural Aug 20, 2021 · The area fraction of martensite-austenite islands increased by raising of Ni content in the weld metal. 3. With increasing Ni content of weld metal till 1.2 wt.%, hardness, yield and ultimate tensile strengths and impact toughness of weld metal increased that were in agreement with microstructural studies. Microstructural evolution and mechanical properties of Jun 03, 2021 · 55NiCrMoV7 hot-work die steel is mainly used to manufacture heavy forgings in the fields of aerospace and automobile. This study aims to clarify the effects of heat treatment on the microstructural evolution and mechanical properties of the steel, in order to find out an optimal heat treatment scheme to obtain an excellent balance of strength, ductility and toughness. The steel was Effect of Microstructural Variation on Tensile and Impact 12, ocfoBER, 1993 THE JAPAI\ FOI.JNDRYMAVS SOCIETY (NTPPON rMONO KYOKAT) FP- 115 - \23 Effect of Microstructural Variation on Tensile Properties and Impact Toughness of Hylroeutectic Al-si Alloy by Mahmoud Fovad Hafiz*l and Toshiro Kobayashi*2 Abstfact Tbe effect of tbe ,nic,tostructutal cbange on tbe tensile prcperties and impact tougbness of Impact Strength of 3D Printed Polyether-ether-ketone Impact Strength of 3D Printed Polyether-ether-ketone (PEEK) Haijun Gong1,*, Xiaodong Xing2, Jan Nel1 1Department of Manufacturing Engineering, Georgia Southern University, Statesboro GA, USA 2College of Mechanical and Electrical Engineering, Harbin Engineering University, Harbin, China *Corresponding author ([email protected]) Abstract Polyether-ether-ketone (PEEK) is a Microstructural analysis and the influence of shot also very low heat input causes lack of fusion in the weld joints. Microstructural variations due to welding are assessed by conducting the micro hardness test, impact toughness test and tensile test. To study the effect of shot peening, the samples are prepared from the DSS welded plate. Analysis of Mechanical Behavior and Microstructural May 09, 2015 · strength, yield strength, ductility, corrosion resistance and creep rupture. These processes also help to improve machining effect, and make them versatile. The mechanical properties can easily be modified by heat treating to suit a particular design purpose.
