Advanced characterization of intermetallic compounds in

Aluminum-steel joints are characterized by electron diffraction-based techniques. EBSD revealed a layer of -Fe 2 Al 5 adjacent to steel and a layer of -Fe 4 Al 13.. SAED and HRTEM led to unequivocal identification of -Fe 2 Al 5 and -Fe 4 Al 13 phases.. Fe 4 Al 17.5 Si 1.5 unambiguously identified for the first time in aluminum-steel welds.

Effects of different welding technologies on metallurgical

The performance evaluation of welded automotive components made in DP steels, with respect to durability or crashworthiness, involves the quantification of the properties change of the welded joint. This work is aimed at evaluating the effects of three different welding technologies (GTAW, PAW, EBW) on DP600 steel properties.

Improved thermal FE numerical model/DoE based on the

Aug 01, 2019 · In this research work, a finite element (FE) numerical analysis was conducted to study the welding thermal field. The finite element model (FEM) was improved by means of the optimal mesh element size using statistical analysis of a design of experiment (DoE) based on the Taguchi method. Through the improved FEM, numerical model were carried out estimations of the penetration depth, Microstructure and mechanical properties of keyhole plasma Aug 01, 2019 · Farabi et al. (2010b) have confirmed experimentally the softening of HAZ due to tempering of large volume of pre-existing martensite in DP980 steel welded by laser welding. The degree of softening was more in DP980 welded joints as compared to DP600 welded joints, which is because the volume fraction of martensite in DP980 is higher. Phases quantification in DP600 steel welded by GTAW It was found that GTAW promoted the development of significant amounts of LB in the HAZ (50.89 %). In contrast atomic force microscopy (AFM) leads to quantify the different phases by the morphology, height and roughness, it was found that martensite (M) dropped down to 7.5% in the intercritical zone (IZ) although PF increases to 92.5% compared with the base metal (BM)

Refill friction stir spot welding of dissimilar aluminum Dec 01, 2017 · AA5754 Al alloy and coated steel were successfully joined by refill friction stir spot welding through the eutectic Al-Si coating. The overlap shear strength increased with plunge depth and reached a high strength plateau which was attributed to maximum bonding size and strong Al/AlSi coating joint interface. The AlSi coating in the as-received Study on the weldability, microstructure and mechanical Aug 05, 2019 · Most of the specimens ruptured in the weld metal . TIG welding process of 617 was done by Young et al., and the strength at the optimized condition was 675 MPa . The strength of welded joint made by pulsed current gas tungsten arc welding method was 734 MPa, which also failed in the weld

Thermal analysis of steel-concrete composite cross sections via CS-ASA/FA. Abstract When exposed to high temperatures, such as in a fire situation, the physical and resistance characteristics of the materials employed in the structure deteriorate as the temperature increases. This fact promotes a considerable loss in the bearing capacity and The microstructure and mechanical properties of novel Jun 22, 2021 · But until now, there are limited reports about the welding of high-Mn TWIP steel. Previously, Fu et al. joined the 32Mn7Cr-0.6Mo-0.3 N super cryogenic high-Mn steel using tungsten inert gas (TIG) welding method with filler metal made from rolling the base material. Their results showed that the decrease of Nitrogen content in welded joint Phases quantification in DP600 steel welded by GTAW Phases quantification in DP600 steel welded by GTAW process using SEM and atomic force microscopy G.Y.
