Effects of Phase Evolution on Mechanical Properties of Laser-Welded Ferritic Fe-Al-Mn-C Steel
In the present study, the evolution of microstructure in laser-welded joints of ferrite-based dual-phase Fe-Al-Mn-C steel sheets was analyzed and its effect on the mechanical properties of the joints was investigated. Laser welding was performed using different powers and welding speeds to attain different heat inputs. Electron backscatter diffraction (EBSD) examinations and hardness measuremen...
متن کاملEffect or Inoculation on Microstructure and Properties of Low C-Mn and Low Alloy Steels
Effect of the addition of various inoculants on the morphology and mechanical properties of low C-Mn and low alloy steel samples is studied by thermal and mechanical processing of the samples after solidification. According to the results obtained from metallographic studies with the electron microscope and microanalysis with x-rays, the distribution of inoculating agents in the steel matrix is...
متن کاملFe–Al–Mn–C lightweight structural alloys: a review on the microstructures and mechanical properties
Adding a large amount of light elements such as aluminum to steels is not a new concept recalling that several Fe-Al-Mn-C alloys were patented in 1950s for replacement of nickel or chromium in corrosion resistance steels. However, the so-called lightweight steels or low-density steels were revisited recently, which is driven by demands from the industry where steel has served as a major structu...
متن کاملEffects of tempering temperature on tensile and hole expansion properties of a C–Mn steel
Effects of tempering temperature on tensile and hole expansion properties in a dual-phase C–Mn steel were investigated. The ultimate tensile strength and yield strength decreased and elongations increased with an increase of tempering temperature. The hole expansion property increased significantly at the tempering temperature ranging from 200 to 300 8C and did not show significant difference w...
متن کاملHIGH TEMPERATURE TENSILE PROPERTIES OF NEW FE-CR-MN DEVELOPED STEEL
Nowadays, Ni-free austenitic stainless steels are being developed rapidly and high price of nickel is one of the most important motivations for this development. At present research a new FeCrMn steel was designed and produced based on Fe-Cr-Mn-C system. Comparative studies on microstructure and high temperature mechanical properties of new steel and AISI 316 steel were done. The results ...
