Special Issue Information

Dear Colleagues,

Traditional processing methods such as thermomechanical processing (TMP) have been used for centuries to improve the properties and microstructure, as well as performance, of metallic materials. However, these processes, e.g., forging, rolling, and extrusion, are energy- and time-intensive. In order to meet the demands for low energy consumption and low greenhouse emissions in today’s manufacturing era, which calls for “green and sustainable technologies”, there has been a growing interest in an integrated approach where other energy fields, such as electrics and magnetics, are coupled with mechanical and thermal approaches to achieve lower processing time and energy. Researchers around the world are exploring various novel energy-efficient processes, such as electropulsing, electrically assisted deformation, electromagnetic processing, electrically assisted annealing/heat treatment, and field-assisted (electric/magnetic/microwave) sintering, spanning from structural, aerospace, medical, to electronics approaches. Besides experimental studies, coupled multiphysics models have been developed to simulate the interplay between thermal, electrical, magnetic, and mechanical effects. These computational simulations complement experimental data by providing insights into the underlying mechanisms and complex interactions between multiple stimuli.

This Special Issue is dedicated to presenting advances in the experimentation and simulation of these novel energy-efficient processes in order to provide and share new insights and practical findings in this field. Potential manuscripts may address, but are not limited to, the following topics:

  • Microstructure evolution (grain size, grain boundaries, texture/microtexture, twinning, etc.);
  • Phase trans/formation and control (intermetallics, precipitation, etc.);
  • Property optimization (strength, nano/microhardness, electrical/thermal conductivity, magnetic, etc.);
  • Process optimization (forming, machining, sintering, heat treatment, deposition, coating, additive manufacturing, etc.).

Preference will be given to manuscripts presenting work on coupled fields. Manuscripts covering other coupling stimuli, such as microwaves, lasers, and ultrasound, will also be considered. The submission of research taking multiscale modeling approaches, such as through phase fields, thermodynamics, and molecular dynamics, is strongly encouraged to bridge the gap between atomistic simulations and macroscopic behavior.

This work demonstrates the capabilities and advantages of a novel sintering technique to fabricate bulk composition gradient materials. Pressure distribution calculations were used to compare several tooling geometries for use with current-activated, pressure-assisted densification or spark plasma sintering to densify a gradient along the long dimension of the specimen. The selected rectangular tooling design retains a low aspect ratio to ensure a uniform pressure distribution during consolidation by using a side loading configuration to form the gradient along the longest dimension. Composition gradients of NixCu1−x, MoxNb1−x, and MoNbTaWHfx (x from 0 to 1) were fabricated with the tooling. The microstructure, composition, and crystal structure were characterized along the gradient in the as-sintered condition and after annealing to partially homogenize the layers. The successful fabrication of a composition gradient in a difficult-to-process material like the refractory multi-principal element alloy system MoNbTaWHfx shows the utility of this approach for high-throughput screening of large material composition spaces.
