Microstructure and Texture of 2205 Duplex Stainless Steel Additive Parts Fabricated by the Cold Metal Transfer (CMT) Wire and Arc Additive Manufacturing (WAAM)

Innovative Process Model of Ti-6al-4v Additive Layer Manufacturing Using Cold Metal Transfer (cmt)

New approaches to modern manufacture have emerged from Additive Layer Manufacturing (ALM) technologies over the last 25 years. These approaches provide form, fit and function to a wide range of metallic alloys and components. Wire + Arc Additive Layer Manufacture (WAALM) has gained the interest of the research community in recent years due to its high deposition rate and efficiency (100%). The ...

Mechanical Properties of Austenitic Stainless Steel Made by Additive Manufacturing

Using uniaxial tensile and hardness testing, we evaluated the variability and anisotropy of the mechanical properties of an austenitic stainless steel, UNS S17400, manufactured by an additive process, selective laser melting. Like wrought materials, the mechanical properties depend on the orientation introduced by the processing. The recommended stress-relief heat treatment increases the tensil...

Mechanical Design of Viscoelastic Parts Fabricated Using Additive Manufacturing Technologies

Mechanical design of viscoelastic parts fabricated using additive manufacturing technologies are under consideration. Such a design is of great importance for obtaining final products with desired shape and strength which are determined by their stress-strain state. Mathematical model of model of viscoelastic solid which grows due to the process of additive manufacturing is proposed. Complete s...

Fabricating Superior NiAl Bronze Components through Wire Arc Additive Manufacturing

Cast nickel aluminum bronze (NAB) alloy is widely used for large engineering components in marine applications due to its excellent mechanical properties and corrosion resistance. Casting porosity, as well as coarse microstructure, however, are accompanied by a decrease in mechanical properties of cast NAB components. Although heat treatment, friction stir processing, and fusion welding were im...
