Abstract

This study investigates the effects of nano-graphite (n-Gr), graphene nanoplatelets (GNPs), and carbon nanotubes (CNTs) as reinforcements on the powder characteristics, and physical and mechanical properties of Al2024-based nanocomposites fabricated via mechanical milling. Reinforcement content was varied from 0.5 wt% to 2 wt%, and the impact of the reinforcement type on particle size, morphology, hardness, and tensile strength was systematically evaluated. Results reveal that n-Gr reinforced composites exhibited flaky morphologies, higher particle sizes, and reduced hardness and tensile strength, attributed to limited embedding and agglomeration effects. In contrast, GNPs and CNTs demonstrated superior reinforcement capabilities, leading to finer powder sizes, enhanced hardness, and improved tensile strength. The largest powder size and the lowest particle hardness were obtained in the K2 sample, measuring 52 µm and 130 HV, respectively, while the smallest powder size and the highest particle hardness were observed in the G2 sample, measuring 29.4 µm and 179 HV, respectively. Among the reinforcements, GNPs showed the highest embedding efficiency and mechanical performance, achieving peak hardness and tensile strength at 1.5 wt% reinforcement. The hardness and tensile strength values of Al sample were 105 HB and 220 MPa, respectively, while the G1.5 sample achieved values of 151 HB and 284 MPa, corresponding to approximately 50 % and 29 % increases. For CNTs reinforcement, the C1 sample exhibited 16 % and 20 % increases, whereas n-Gr reinforcements consistently resulted in reductions.

期刊介绍: The aim of Advanced Powder Technology is to meet the demand for an international journal that integrates all aspects of science and technology research on powder and particulate materials. The journal fulfills this purpose by publishing original research papers, rapid communications, reviews, and translated articles by prominent researchers worldwide. The editorial work of Advanced Powder Technology, which was founded as the International Journal of the Society of Powder Technology, Japan, is now shared by distinguished board members, who operate in a unique framework designed to respond to the increasing global demand for articles on not only powder and particles, but also on various materials produced from them. Advanced Powder Technology covers various areas, but a discussion of powder and particles is required in articles. Topics include: Production of powder and particulate materials in gases and liquids(nanoparticles, fine ceramics, pharmaceuticals, novel functional materials, etc.); Aerosol and colloidal processing; Powder and particle characterization; Dynamics and phenomena; Calculation and simulation (CFD, DEM, Monte Carlo method, population balance, etc.); Measurement and control of powder processes; Particle modification; Comminution; Powder handling and operations (storage, transport, granulation, separation, fluidization, etc.)
