Special Issue Information

Dear Colleagues,

Powder bed fusion (PBF) technology has experienced rapid development in the last decade.

PBF technology has been successfully applied to a wide range of material systems, such as metals, polymers, ceramics, etc., of which the processing capabilities and quality show advantages to traditional processing routes. In the meantime, with the deepening of this research and the continuous demands of the industry, many innovative concepts have emerged, such as energy-field-assisted manufacturing, multi-material manufacturing, (laser) beam shaping, and hybrid additive/subtractive manufacturing. Besides those conceptual improvements, advances in PBF technologies are reflected in various aspects, including novel design and modeling, equipment upgrades, the expansion of applicable materials, appropriate post-processing methods, process monitoring, and quality evaluation.

In this Special Issue, we aim to present a comprehensive collection of research articles, reviews, and short communications, so as to highlight recent advances with regard to powder bed fusion technologies. Suitable topics for this Special Issue include, but are not limited to, the following:

Novel materials fabricated by PBF technologies;
Energy-field-assisted manufacturing;

Abstract

For advancing manufacturing, arising AM, with an inverse philosophical approach compared to conventional procedures, has benefits that include intricate fabrication, reduced material waste, flexible design, and more. Regardless of its potential, AM must overcome several challenges due to multi-physical processes with miscellaneous physical stimuli in diverse materials systems and situations, such as anisotropic microstructure and mechanical properties, a restricted choice of materials, defects, and high cost. Unlike conventional experimental work that requires extensive trial and error resources and FEM, which generally consumes substantial computational power, the analytical approach based on physics is an exceptional choice. Understanding the relationship between the microstructure and material properties of the fabricated parts is a crucial focus in AM research. Texture is a vital factor in almost every modern industry. This study first proposed a physics-based model to foreshadow the multi-phase crystallographic orientation distribution in Ti-6Al-4V LPBF while considering the part boundary conditions due to the importance of part geometry in real industry. The thermal distribution obtained from this function operates as the information for the single-phase crystallographic texture model. In this model, we forerun and validate the orientations of single-phase materials utilizing three Euler Angles with the principles of CET and thermodynamics, as well as the intensity of the texture by approximating them with published results. Then, we transform the single-phase texture into a dual-phase texture in Bunge calculation, illustrating visualized by pole figures of both BCC and HCP phases. The tendency and appearances of both BCC and HCP phases in pole figures predicted agree well with the experimental results. This texture evolution model provides a new paradigm for future researchers to model the texture or microstructure evolution semi-analytically and save many computational resources in a real-world perspective. Others have not yet done this work about simulating the multi-phase texture in an analytical approach, so this work bridges the gap in this field. Furthermore, this paper establishes the foundation for future research on materials properties affected by microstructure or texture in academic and industrial environments. The precision and dependability of the results obtained through this method make it a valuable tool for ongoing research and advancement. Full article
