Focus Issue: Journal of Materials Research

Additive Manufacturing of Metals: Complex Microstructures and Architecture Design
Issue date: August, 2020
Submission deadline: January 1, 2020

Additive manufacturing (AM) is a disruptive technology, not only because it enables the production of components with complex geometries, but also because it provides unique opportunities for microstructure control and materials design. In contrast to conventional manufacturing technologies such as casting, forging, and hot rolling, AM offers additional degrees of freedom to “architect” materials microstructure across length scales. Both beam-based processes—such as power bed fusion (PBF) and directed energy deposition (DED)—as well as non-beam-based processes—such as cold spray, additive friction stir deposition, and ultrasonic additive manufacturing—unlock new opportunities for the control of microstructure and architecture for desired mechanical and functional properties. Understanding microstructure evolution and the resulting material’s behavior is key to developing novel material designs by AM methods. The goal of this Focus Issue is to highlight research on AM-produced microstructures and their impact on mechanical and physical properties of metallic materials. Both experimental and modeling submissions are encouraged, especially papers in which modeling or theory is applied and validated experimentally. Materials systems of interest include, but are not limited to, structural materials, different types of steels, aluminum, titanium, nickel, copper, cobalt, refractory metals, shape-memory alloys, high entropy alloys, and bulk metallic glasses.

Contributing papers are solicited in the following areas:

• Microstructural evolution during the AM process.
• Microstructure response of AM components to post-processing conditions.
• Simulation of microstructure stability and evolution during or post the AM process
• Novel alloy design tailored for AM.
• Architecture design in using AM methods.
• Microstructure and property relationship of the AM components.
• Artificial intelligence aided design for the microstructure or architecture optimization

Manuscript submission:

To be considered for this issue, new and previously unpublished results significant to the development of this field should be presented. The manuscripts must be submitted via the JMR electronic submission system by January 1, 2020. Manuscripts submitted after this deadline will not be considered for the issue due to time constraints on the review process. Please select “Additive Manufacturing of Metals: Complex Microstructures and Architecture Design” as the Focus Issue designation. Note our manuscript submission minimum length of 3250 words, excluding figures, captions, and references, with at least 6 and no more than 10 figures and tables combined. Review articles may be longer but must be pre-approved by a proposal to the Guest Editors via jmr@mrs.org. The proposal form and author instructions may be found at www.mrs.org/jmr-instructions. All manuscripts will be reviewed in a normal but expedited fashion. Papers submitted by the deadline and subsequently accepted will be published in the Focus Issue. Other manuscripts that are acceptable but cannot be included in the issue will be scheduled for publication in a subsequent issue of JMR.

Please direct questions to jmr@mrs.org.
