Powder and Wire Metallurgy (PW/M) is a commonplace fabrication and processing
method for high throughput part production in industrial settings.
Additionally, PW/M fabrication and processing advancement also is an essential
counterpart to the advancement of additive manufacturing (AM) with powder-based
AM methods. Novel and intensive research is ongoing in innovative, traditional,
and emerging magnetic materials and functional materials; however, the
practical application is limited by the ability to form these typically brittle
materials into the shapes that are designed for the applications. At this time,
advanced powder synthesis and processing, including additive manufacturing, can
provide a way to form these materials into final shapes for applications.
The purpose of this symposium is to tie both magnetic and functional materials
to advanced powder synthesis and additive manufacturing, as well as other
advanced processing approaches and discuss aspects such as process-property
relationships, functionality, and/or application performance. Magnetic and

• And other powder and wire synthesis approaches
Topics of interest for advanced powder processing of magnetic/functional
materials include, but are not limited to: i) additive manufacturing (binder

Electrical steels are an essential energy converting material widely used in
generators, transformers, electric motors and other electromagnetic devices to
confine the magnetic flux and amplify the conversions between electricity and
other forms of energy. The efficiency of these devices is largely determined by
the magnetic properties of the electrical steel sheets, and has a huge impact

The need to develop a decarbonized economy to curb human-caused climate change
has been reflected through several international agreements. Advanced magnetic
materials are key components in many applications that are critical to the
development of such an economy where environmentally benign supply chains and

The increasing need for improved energy efficiency in numerous technologies
drives the need for the development of advanced magnetic metals. For example,
improvements in hard and soft magnetic materials are essential to enabling
high-efficiency energy conversion technologies such as compact
motor-generators. Similarly, caloric materials show great promise for increased
cooling efficiency and longer operational lifespans, while eliminating
greenhouse gases (many refrigerant gases have 1500-4000X the atmospheric
warming potential of CO2). Beyond improved performance, these materials must
also address critical materials challenges—where supply chain uncertainty can
hamper widespread commercialization. For example, high-performance magnetic and
magneto-responsive materials typically rely on rare earth elements, which are
subject to supply/demand instability leading to dramatic changes in price.
Disruption of the Nd supply in 2011 led to an increase in price by a factor of
ten! Other technologies are enabled by minor metals such as gallium which is a
co-product from aluminum mining. Demand for Ga is rapidly growing within the
semiconductor industry (GaN), limiting its availability and increasing the cost
for applications such as Galfenol—a magnetostrictive material. Therefore, there
is a clear need to develop classes of advanced magnetic materials with
decreased reliance on critical elements. Addressing this challenge requires
developing new synthesis approaches for structures difficult to realize and
advanced characterization to identify and optimize material performance.
Synthesis techniques include pathways to: 1) Obtain and retain metastable
phases and/or nanostructures in complex systems; 2) Scale-up synthesis to bulk
geometries while maintaining non-equilibrium phases/structures; and 3) Precise
control over chemistry, texture, and defects during synthesis. Equally
important is advanced characterization of functional materials including: 1)
Advanced electron microscopy characterization of atomic- and nano-scale
structures; 2) In situ characterization (X-ray, neutron, etc.) of phase
stability in complex systems; and 3) Physical property measurements.
This symposium will cover all aspects of advanced synthesis and
characterization of high-performance functional materials. Specific topics of
interest will include permanent magnet materials (rare earth and rare earth
free), soft magnetic materials, calorics (magneto and elasto), and
magnetostrictive materials.
Additive manufacturing (AM) is a popular choice to fabricate complex designs
such as porous structures and also for reducing the material waste during the
fabrication step. AM also offers the unique capability to control the nano,
micro, and macrostructure of a material, thus enabling the user to control the
material properties. All these attributes make AM a potential candidate for
functional, energy, and magnetic materials. Functional and magnetic materials
such as shape memory alloys, magnetic shape memory alloys, soft/hard magnetic
materials, and piezoelectric materials are sensitive to the macro and
microstructure of the material. Recent work in the area of shape memory alloys
has demonstrated improved superelasticity in additively manufactured Nitinol
without the need for postprocess heat treatment. Similarly, novel architectures
for Lithium batteries fabricated using AM showed an improved performance
compared to traditional batteries owing to the inherent porosity in the AM
structures. Based on these prior studies, it is reasonable to conclude that a
detailed understanding of the process-structure-property relationships in
functional, energy, and magnetic materials can open up tremendous opportunities
to fabricate materials using AM with applications ranging from medical to
defense to energy industries. These developments unique to AM requires a
detailed understanding of (i) identifying the optimized
architecture/microstructure and (ii) achieving optimized structures via AM.
The goal of this symposium is to provide a platform to discuss ongoing efforts
in using AM for functional, energy, and magnetic materials. Topics of interest
include (i) use of Nano-micro-macro scale metal AM processes for functional,
energy, and magnetic materials; (ii) process-structure-property relationships;
(iii) strategies for design and microstructure optimization using AM; (iv)
modeling of process, microstructure and properties of AM of functional, energy,
and magnetic materials.
This symposium focuses on structure, properties, processing, and performance
interrelationships for traditional and emerging magnetic materials. The
symposium will cover soft and hard magnetic materials, magnetocaloric
materials, magnetoelastic, magnetoelectric, magnetostrictive, and
thermoelectric materials. The scope includes new material compositions, novel
characterization approaches, and application driven magnetic component design
for energy conversion, sensors, and actuators. We also encourage topics that
focus on the economic and supply chain impacts that magnetic materials have on
manufacturing and adaptation of technologies and applications as well as novel
computational approaches used for the discovery and development of advanced
magnetic material.
The symposium will place particular interest on the following topics:
1. Emerging and established advanced manufacturing methods
a. bulk manufacturing of advanced magnetic materials e.g.
nanostructured, amorphous,
b. thermal-mechanical / thermal-magnetic processing,
c. energy dense processing using RF, microwave, high pressure or high
magnetic fields
2. Novel magnetic materials and processing techniques for sensor and
actuator applications
3. System level implications and interactions of magnetic components and
magnetic design
This symposium focuses on structure, property, processing, and performance
interrelationships for emerging soft magnetic materials, permanent magnets, and
magnetocaloric materials; hybrid materials, such as materials that display both
a magnetocaloric and elastocaloric effect; and magnetic materials for sensors
and actuators. The scope includes new material compositions, advanced
manufacturing methods, novel characterization approaches, and applications.
We also encourage topics that focus on the economic impacts that magnetic
materials have on manufacturing and adaptation of technologies and
applications. The symposium will place particular interest on emerging and
established advanced manufacturing methods such as 1. additive manufacturing,
2. top-down and bottom-up bulk nano-manufacturing, 3. thermal-mechanical and
thermal magnetic processing, 4. energy dense processing such as RF, microwave,
high pressure, and high magnetic field processing and 5. Novel magnetic
materials for sensor and actuator applications and their advanced processing.
