Effects of Fe2O3 nanoparticle on quality of medium-density polyethylene friction stir weld joint
This study presents a comprehensive investigation into the effects of incorporating Fe₂O₃ nanoparticles in medium-density polyethylene (MDPE) during friction stir welding (FSW). It systematically explores the metallurgical and mechanical characteristics through quantitative analyses. FSW with Fe₂O₃ nanoparticles (n-FSW) mitigates thermo-mechanical changes in the upper joint area, enhancing the overall structural and mechanical properties of the welded joint. Examination of the stir zone indicates a slightly larger area in n-FSW, highlighting the influence of nanoparticle reinforcement. The ultimate tensile strength (UTS) of the n-FSW sample improved to 27 MPa, which is 34% higher than the 21 MPa of the FSW sample. Additionally, the formation of microscale voids in the stir zone of n-FSW was reduced by 60% compared to the FSW sample. The impact energy of the n-FSW sample was 4 J/cm2 more than that of the FSW sample. Fracture surface analysis reveals nanoparticle contributions to fracture mechanics, while impact properties suggest potential air bubble entrapment.
期刊介绍:
Archives of Civil and Mechanical Engineering (ACME) publishes both theoretical and experimental original research articles which explore or exploit new ideas and techniques in three main areas: structural engineering, mechanics of materials and materials science.
The aim of the journal is to advance science related to structural engineering focusing on structures, machines and mechanical systems. The journal also promotes advancement in the area of mechanics of materials, by publishing most recent findings in elasticity, plasticity, rheology, fatigue and fracture mechanics.
The third area the journal is concentrating on is materials science, with emphasis on metals, composites, etc., their structures and properties as well as methods of evaluation.
In addition to research papers, the Editorial Board welcomes state-of-the-art reviews on specialized topics. All such articles have to be sent to the Editor-in-Chief before submission for pre-submission review process. Only articles approved by the Editor-in-Chief in pre-submission process can be submitted to the journal for further processing. Approval in pre-submission stage doesn''t guarantee acceptance for publication as all papers are subject to a regular referee procedure.
