Processing of a Martensitic Tool Steel by Wire-Arc Additive Manufacturing

Materials, 2022
This work investigates the processability of hot-work tool steels by wire-arc additive manufacturing (DED-Arc) from metal-cored wires. The investigations were carried out with the hot-work tool steel X36CrMoWVTi10-3-2. It is shown that a crack-free processing from metal-cored wire is possible, resulting from a low martensite start (Ms) temperature ...

Techno-Economic Analysis of Hybrid Layered Manufacturing [PDF]

, 2005
Subtractive manufacturing (CNC machining) has high quality of geometric and material properties but is slow, costly and infeasible in some cases; additive manufacturing (RP) is just the opposite.

The effectiveness of combining rolling deformation with wire-arc additive manufacture on β-Grain refinement and texture modification in Ti-6Al-4V [PDF]

, 2016
In Additive Manufacture (AM), with the widely used titanium alloy Ti–6Al–4V, the solidification conditions typically result in undesirable, coarse-columnar, primary β grain structures.

Heat sources in wire arc additive manufacturing and their impact on macro-microstructural characteristics and mechanical properties – An overview

Smart Materials in Manufacturing
The layer-by-layer production idea known as Wire Arc Additive Manufacturing (WAAM) is suggested as a viable substitute for conventional subtractive methods because of its ability to produce massive metallic components with a moderate degree of geometric ...

Arc Behavior in Wire Arc Additive Manufacturing Process

Procedia Manufacturing, 2020
Abstract The welding arc behavior in a wire arc additive manufacturing process was studied while building a ten-layer wall over a base plate using a cold metal transfer (CMT) power source. The real-time recorded welding current, voltage, thermal cycles at the base plate, and the synchronized high-speed arc images with each deposited layer were used ...

Residual stress and texture control in Ti-6Al-4V wire + arc additively manufactured intersections by stress relief and rolling [PDF]

, 2018
Additively manufactured intersections have the theoretical risk to contain hydrostatic tensile residual stresses, which eventually cannot be thermally stress relieved.

Design study for wire and arc additive manufacture [PDF]

International Journal of Product Development, 2014
Additive Manufacture (AM) is a technique whereby freeform structures are produced by building up material in a layer by layer fashion. Among the different AM processes, Wire and Arc Additive Manufacture (WAAM) has the ability to manufacture large custom-made metal workpiece with high efficiency.

Fatigue crack propagation behaviour in wire+arc additive manufactured Ti‐6Al‐4V: Effects of microstructure and residual stress [PDF]

, 2016
Fatigue crack propagation tests of Ti‐6Al‐4V fabricated by the Wire+Arc Additive Manufacturing (WAAM) process are analysed. Crack growth rate and trajectory are examined before and after the crack tip crossing an interface between the WAAM and wrought ...
