Special Issue Information

Dear Colleagues,

High-energy ball milling (HEBM) has attracted increasing attention within the various branches of the scientific community. The HEBM of powder mixtures in high-speed planetary ball mills, shakers and other milling equipment allows for the production of nanostructured composites (including reactive ones), solid solutions, metastable phases, pseudoalloys, and various other materials. In the case of metallic systems, high-energy ball treatment induces the formation of multilayered structures, achieving a highly specific surface between the components.

The science of mechanochemistry continues to have multiple blind spots. Therefore, we are calling for papers dedicated to the various aspects of high-energy ball milling. The following aspects are of particular interest:

  1. The relation between the processing conditions for HEBM, phase and structure formation mechanisms, and the properties of the produced powders.
  2. The theoretical modeling and experimental assessment of the mechanochemical processes, including in situ assessment.
  3. The influence of mechanochemical processing on sintering and the properties of materials.
  4. The combination of HEBM and novel consolidation processes.
  5. The reactivity and energy storage capacity of mechanically activated mixtures.
  6. Reports on the industrial implementation of HEBM-related processes.
  7. Advancements in Selective Laser Melting

Both experimental reports and reviews are welcomed for submission.

Laser powder bed fusion (L-PBF) stands out as a promising approach within the realm of additive manufacturing, particularly for the synthesis of CNT-AlSi10Mg nanocomposites. This review delves into a thorough exploration of the transformation in microstructure, the impact of processing variables, and the physico-mechanical characteristics of CNT-AlSi10Mg nanocomposites crafted via the L-PBF technique. Moreover, it consolidates a substantial corpus of recent research, proffering invaluable insights into optimizing L-PBF parameters to attain the desired microstructures and enhanced properties. The review centers its attention on pivotal facets, including the dispersion and distribution of CNTs, the formation of porosity, and their subsequent influence on wear resistance, electrical and thermal conductivity, tensile strength, thermal expansion, and hardness. In line with a logical progression, this review paper endeavors to illuminate the chemical composition, traits, and phase configuration of AlSi10Mg-based parts fabricated via L-PBF, juxtaposing them with their conventionally manufactured counterparts. Emphasis has been placed on elucidating the connection between the microstructural evolution of these nanocomposites and the resultant physico-mechanical properties. Quantitative data culled from the literature indicate that L-PBF-produced parts exhibit a microhardness of 151 HV, a relative density of 99.7%, an ultimate tensile strength of 70×103 mm3N.m, and a tensile strength of 756 MPa.
