Full article (This article belongs to the Special Issue Damage and Mechanical Properties of Steels )[plate]Microstructure Evolution, Mechanical Properties and [steel]In this work, the microstructure and mechanical properties of an additively manufactured X3NiCoMoTi18 9 5 maraging steel were determined. Optical and electron microscopies revealed the formation of melt pool boundaries and epitaxial grain growth with cellular dendritic structures after the laser powder bed fusion (LPBF) process. The cooling rate is estimated to be around 106 °C/s
In order to obtain useful engineering properties, martensitic stainless steels are normally tempered. The tempering temperature used has a large influence on the final properties of the steel. The effect of tempering temperature on the mechanical properties of a [plate]The Influence of Current Supply Type on the Composition [steel]The chemical composition, strength, microstructure, and toughness of the deposits were studied in the as welded condition. For the C Mn Ni 1G welds (and to a lesser extent for the C Mn welds), manganese and silicon decreased in the order DC reverse polarity, AC and DC straight polarity.[plate]Evaluation of microstructure and fatigue properties in [steel]H. K. D. H. Bhadeshia and R. W. K. Honeycombe, Steels Microstructure and Properties, 3rd ed. ( Butterworth Heinemann, Burlington, 2006). The hardness was not recovered to the substrate level, evident that the entire cross sectional view of the substrate was heat affected during the
Feb 16, 2011 · Heat treatment is used to modify properties of materials in addition to hardening and softening. These processes modify the behavior of the steels in a beneficial manner to maximize service life, e.g., stress relieving, or strength properties, e.g., cryogenic treatment, or some other desirable properties, e.g., spring aging. Hot Metal Decorative.[plate]Evaluation of microstructure and fatigue properties in [steel]H. K. D. H. Bhadeshia and R. W. K. Honeycombe, Steels Microstructure and Properties, 3rd ed.

Microstructures in coarse grained steels are much easier to observe than in fine grained steels. Of course, steels are normally made with a fine grain size for best mechanical properties. In general, it is easiest to identify heat treated structures after
Mar 06, 2016 · The microstructure at the bottom of Fig. 3 (left side) is normally formed on heating the steel from room temperature to 760 deg C. This example explains one of the interesting aspects of steels that the microstructure can be controlled by heat treatment and it is known that the mechanical properties of steels are controlled by microstructure.[plate]Effects of shielding gas composition on the welding [steel]The effects of shielding gas composition on the welding stability, microstructure and mechanical properties were analyzed. The results show that the weld seam forming and welding stability are improved when 1%O 2 is added to the mixture of Ar + N 2, and the nitrogen content in [plate]Evaluation of microstructure and fatigue properties in [steel]H. K. D. H. Bhadeshia and R. W. K. Honeycombe, Steels Microstructure and Properties, 3rd ed. ( Butterworth Heinemann, Burlington, 2006). The hardness was not recovered to the substrate level, evident that the entire cross sectional view of the substrate was heat affected during the
Nov 27, 2015 · Steels conforming to the specifications are to be weldable by established workshop methods. Where applicable, this includes the measures necessary to ensure the quality of the welds, e.g. preheating and/or post weld heat treatments. The mechanical properties of the steels as stated in the specifications are to be verified by means of tensile tests.[plate]Control of High Strength Low Alloy (HSLA) Steel Properties [steel]This processing is widely used to obtain reliable mechanical properties in steels for pipelines, bridges, offshore platforms, and many other engineering applications. The use of controlled rolling has resulted in improved combinations of strength and toughness and further reductions in the carbon content of microalloyed HSLA steels.[plate]Comparative study of mechanical, corrosion and erosion [steel]AbstractDuplex stainless steels (DSSs) used in subsea structures and desalination industries require high corrosion and erosion resistance as well as excellent mechanical properties.The newly introduced cast duplex grade ASTM A890 7A has a unique composition and is expected to have a much better resistance to corrosion and erosion compared with the super duplex grades 5A and 6A.
3.2 Mechanical Behavior of Bulk Samples under Quasistatic Loading Conditions. These changes in the microstructure have a significant influence on the material properties. In Figure 3a, a representative engineering tensile stressstrain curve of FeMnCS (SLM) is presented in comparison with its cast counterpart.
