Abstract

A bimetallic additively-manufactured structure (BAMS) is a type of functionally-graded multi-material structure used for achieving different complementary material properties within the same structure as well as cost optimization. Wire + arc additive manufacturing (WAAM) offers the capability to fabricate the BAMS in a simultaneous or sequential way. To fully utilize the benefits of the BAMS, the interfacial joint should be strong, and each of the constituents should have reasonable mechanical integrity. For this, a BAMS of low-carbon steel and austenitic-stainless steel was fabricated using a gas-metal-arc-welding (GMAW)-based WAAM process. Then, the BAMS was heat-treated at a range of 800 °C to 1100 °C and 30 min to 2 h. This resulted in 35% and 250% increases in the ultimate tensile strength and elongation, compared to the as-deposited BAMS. After the heat-treatment, the failure location moved from the low-carbon-steel to the stainless-steel side. Additionally, scanning electron microscopy (SEM), energy-dispersive X-ray spectroscopy (EDAx), and the Vickers hardness test were used to characterize the BAMS. In this paper, it is experimentally validated that heat-treatment at 950 °C-1 h is the near-optimal condition for the BAMS.

Interfacial characteristics of P91 steel - Inconel 740H bimetallic structure fabricated using wire-arc additive manufacturing

Journal Article Sridar, Soumya ; Klecka, Michael A. ; Xiong, Wei - Journal of Materials Processing Technology

Although bimetallic structures can offer unique solutions to engineering problems with varying functionality, joining two dissimilar alloys using additive manufacturing involves challenges such as cracking and segregation. In this work, bimetallic structures of Inconel 740H superalloy and P91 steel are processed using wire-arc additive manufacturing (WAAM) for the first time. P91 steel is directly deposited over 740H with a cooling time of 20 minutes in between the two depositions. During microstructure characterization, a large gradient zone with coarse grains spanning for ~2200 μm is observed. Moreover, the microhardness of the gradient zone is the least in comparison with the P91more »« less

Post-build thermomechanical processing of wire arc additively manufactured stainless steel for improved mechanical properties and reduction of crystallographic texture

Journal Article Elmer, John W. ; Fisher, Karl ; Gibbs, Gordon ; ... - Additive Manufacturing

Wire-arc additive manufacturing (WAAM) was used to fabricate 304 L stainless steel plates for the purpose of characterizing texture and anisotropic behavior in the as-built parts, followed by post-build rolling and heattreating to modify mechanical properties and reduce texture. The plates were made using a robotic controlled gas metal arc (GMA) welding system designed for high deposition rates and were characterized using uniaxial tensile testing, macro- and micro-hardness, and optical microscopy. In addition, resonant ultrasound spectroscopy (RUS) was used for the first time of WAAM plates to measure the anisotropic elastic modulus, shear modulus and Poisson’s ratio. Post processing consistedmore »« less

Analysis of Favorable Process Conditions for the Manufacturing of Thin-Wall Pieces of Mild Steel Obtained by Wire and Arc Additive Manufacturing (WAAM)

Journal Article Prado-Cerqueira, José Luis ; Camacho, Ana ; Diéguez, José Luis ; ... - Materials

Here, one of the challenges in additive manufacturing (AM) of metallic materials is to obtain workpieces free of defects with excellent physical, mechanical, and metallurgical properties. In wire and arc additive manufacturing (WAAM) the influences of process conditions on thermal history, microstructure and resultant mechanical and surface properties of parts must be analyzed. In this work, 3D metallic parts of mild steel wire (American Welding Society-AWS ER70S-6) are built with a WAAM process by depositing layers of material on a substrate of a S235 JR steel sheet of 3 mm thickness under different process conditions, using as welding process themore »« less

Additive Manufacture of Multi-Functional, Large-Scale Components

Conference Lillo, Thomas M ; Glazoff, Michael V ; Larsen, Eric C ; ...

The poster summarizes the main results for a LDRD focused on developing a arc-based additive manufacturing (AM) system capable of fabricating large components with a composition gradient otherwise known as functionally graded materials (FGMs). FGMs are capable of addressing local extreme conditions in an optimal and cost-effective manner. The AM system (referred to as multi-Wire Arc Additive Manufacturing or m-WAAM) consisted of modifying a standard automated gas tungsten arc welding system to deliver multiple welding wires to the weld pool at controlled rates to deposit desired alloy compositions at critical locations. Numerous shapes and composition gradients were fabricated with themore »« less

Evolution of carbide precipitates in Haynes® 282 superalloy processed by wire arc additive manufacturing

Journal Article Zhang, Hanlei ; Wang, Yuankang ; De Vecchis, Rafael Rodriguez ; ... - Journal of Materials Processing Technology

Precipitation hardening regulated with heat treatments is a critical technique for tuning the mechanical properties of Ni-based superalloys fabricated with additive manufacturing, where mechanical deformation is no longer viable for microstructural refinement. As one of the key precipitates, carbides prevail in the additively manufactured alloys, whose precipitation kinetics remain largely vague. This work studies the influence of heat treatments on the evolution of MC- and M₂₃C₆-type carbides within a Haynes® 282 superalloy prepared by wire arc additive manufacturing (WAAM). SEM-EDS analysis was performed to identify the evolution pathways of the carbides, and TEM and XRD characterizations were carried out tomore »« less
