Grain Refinement, Strengthening, and Deformation Mechanisms in Additively Manufactured Alloys

Dear Colleagues,

Additive manufacturing (AM) has emerged as a revolutionary manufacturing technique that enables the production of complex geometries and customized components with exceptional precision. In recent years, the application of AM in the production of metallic alloys has gained significant attention across various industries, including the aerospace, automotive, and biomedical. However, to fully harness the potential of additively manufactured alloys, it is crucial to understand and optimize the microstructural characteristics that directly influence their mechanical properties and performance.

Scope and Objectives:

This Special Issue of the Journal of Materials aims to explore the fundamental aspects of grain refinement, the strengthening mechanisms, and deformation behavior of additively manufactured alloys. The aim is to gather cutting-edge research that addresses the challenges and advances in the understanding of microstructural evolution, mechanical properties, and performance of these materials. We welcome original research articles, reviews, and perspective papers that encompass a wide range of topics related to the following:

Microstructural characterization of additively manufactured alloys:

• Grain refinement mechanisms during the additive manufacturing process.
• Effect of processing parameters on microstructural evolution.
• Role of alloy composition and elemental segregation on microstructure.

Strengthening mechanisms in additively manufactured alloys:

• Precipitation hardening and strengthening in alloy systems.
• Grain boundary strengthening and nanoscale reinforcement.
• Influence of heat treatment and post-processing.

Deformation behavior and mechanical properties of additively manufactured alloys:

• Tensile, fatigue, and creep behavior of AM alloys.
• Microstructural effects on mechanical properties and performance.
• Modeling and simulation of deformation mechanisms.

Advanced characterization techniques and in-situ observations:

• In situ microscopy and diffraction techniques for real-time observations.
• Advanced characterization methods for microstructural analysis.
• Correlation between microstructure and mechanical behavior.

Design optimization and practical applications:

• Design strategies for enhanced mechanical properties in AM alloys.
• Performance evaluation of additively manufactured components.
• Case studies demonstrating the practical applications of AM alloys.
