Abstract The complex concentration alloys are considered to have excellent mechanical properties due to the combined effects of heterogeneous composition and microstructure. However, it is difficult for existing simulation methods to capture the significant modulation of mechanical properties by the formation and motion of grain boundaries of complex concentration alloys at the microsecond and nanometer scales. To address this, we utilize the phase field crystal model that combines molecular dynamics and traditional phase field advantages to systematically study real-time grain boundary formation and motion in complex concentration alloys [1]. Meanwhile, we investigated the compositional fluctuations of More >

Abstract Hot isostatic pressing (HIP) is often utilized to obtain laser powder bed fused (LPBF) Ti-6Al-4V with good mechanical properties. To uncover the underlying mechanisms by which HIP improves the mechanical properties, several mechanisms are considered and examined against experimental data sets available in the literature. The results suggest that HIP improves mechanical properties by both reducing defect sizes below a critical threshold and altering the microstructure surrounding defects. Based on these findings, a pore healing model was developed, and optimized HIP processing parameter range (temperature, pressure, and soaking time) were proposed. Severe plastic deformation driven… More >

Abstract Complex hierarchical structure in nature with remarkable performances of such as lightweight, high stiffness and strength, and so on, has inspired researchers designing and fabricating aligned structures for reinforced composites. Conventional techniques like freeze-casting, self-assembly, wet-spinning, shear force, electric, and magnetic field have been demonstrated to achieve excellent reinforced structures. Still, they are limited to microstructure control and small-sized samples. While 3D printing techniques enable to achieve a large diversity of dimensions, multimaterial and multifunctional 3D structures. Particularly, recent 3D printing combined with external force e.g., shear force, magnetic and electrical field has been employed… More >

Abstract Additive manufacturing (AM) reveals high anisotropy in mechanical properties due to the thermal accumulation induced microstructures. How to reveal the internal connection between the microstructures and the mechanical properties in additive manufacturing is a challenge. There are many methods to predict the mechanical properties based on the microstructural evolutions in additive manufacturing [1–3]. Here we summarized the main methods for the prediction of the mechanical properties in additive manufacturing, including crystal plasticity finite element method (CPFEM), dislocation dynamics (DD), and molecular dynamics (MD). We systematically examine these primary approaches for mechanical property predictions in AM,… More >

Abstract In this study, the polyurethanes (PU) were synthesized from 4,4^′-methylene diphenyl diisocyanate and biobased ethoxylated castor oil or one mixture of ethoxylated and neat castor oil by direct mixing method. Utilization of ethoxylated castor oil increases the tensile strength of PU up to 2.75 times (from 3.2 to 8.8 MPa), compared to PU based on neat castor oil. The PU composites filled with birch flour, diatomite, and their mixture were prepared using a homemade dissolver with a cutter-shaped attachment at a speed of 1500 r min⁻¹. The tensile strength of PU composites filled with birch flour… More > Graphic Abstract

Abstract Biocomposites are one of the environmentally friendly materials as a substitute for synthetic plastics used for various applications in the automotive, household appliances industry, and interiors. In this study, biocomposites from Polylactic Acid (PLA) and sugarcane bagasse fibers (SBF) were made using the 3D Printing method. The effect of alkalization with NaOH of 0 (untreated), 4%, 6%, and 8% of the fibers were studied. The SBF in PLA was kept at 2% v/v from the total biocomposite. The characterization of all biocomposite tested using tensile, flexural, impact, scanning electron microscope (SEM), thermogravimetric analysis (TGA), and Fourier… More > Graphic Abstract

Abstract Machine learning models can predict material properties quickly and accurately at a low computational cost. This study generated novel hybridized nanocomposites with unsaturated polyester resin as the matrix and Areca fruit husk fiber (AFHF), tamarind fruit fiber (TFF), and nano-sized coconut shell powder (NCSP). It is challenging to determine the optimal proportion of raw materials in this composite to achieve maximum mechanical properties. This task was accomplished with the help of ML techniques in this study. The tensile strength of the hybridized nanocomposite was increased by 134.06% compared to the neat unsaturated polyester resin at… More >

Abstract Sugarcane bagasse (SCB) is a promising natural fiber for bio-based composites, but its high moisture absorption and poor interfacial adhesion with polymer matrices limit mechanical performance. While chemical treatments have been extensively explored, limited research has addressed how thermal treatment alone alters the surface properties and reinforcing behavior of SCB fibers. This study aims to fill that gap by investigating the effects of heat treatment on SCB fiber structure and its performance in starch/poly (vinyl alcohol) (PVA) composites. Characterization techniques including Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), and scanning… More >

Abstract Clarify the mechanical properties of different laminations and the fracture mechanism of continental shale under in-situ stress can provide theoretical basis for more comprehensive evaluation of the fracability of continental shale oil reservoir. The Chang 72 continental shale was used to investigate the mechanical properties of laminations and the effect of natural structure on the crack propagation of the shale. The X-ray diffraction (XRD) and thin section tests show that the laminations contain two types: bright sandy lamination with void structure and dark muddy lamination with layer structure. The real-time Computed Tomography (CT) uniaxial compression… More >

Abstract In the production process of silicone sealant, mineral oil is used to replace methyl silicone oil plasticizer in silicone sealant to reduce costs and increase efficiency. However, the silicone sealant content in mineral oil is prone to premature aging, which significantly reduces the mechanical properties of the silicone sealant and severely affects its service life. At the same time, there are few reports on the simulation research of the performance of silicone sealant. In this study, three mixed system models of crosslinking silicone sealant/plasticizer are constructed by the molecular dynamics simulation method, and the effect… More >
