Forthcoming articles have been peer-reviewed and accepted for publication but are pending final changes, are not yet published and may not appear here in their final order of publication until they are assigned to issues. Therefore, the content conforms to our standards but the presentation (e.g. typesetting and proof-reading) is not necessarily up to the Inderscience standard. Additionally, titles, authors, abstracts and keywords may change before publication. Articles will not be published until the final proofs are validated by their authors.

Forthcoming articles must be purchased for the purposes of research, teaching and private study only. These articles can be cited using the expression "in press". For example: Smith, J. (in press). Article Title. Journal Title.

  • First-principles investigation of Hexagonal Boron-Carbon-Nitride (h-BCN) nanosheet (2D) as gas sensor towards toxic gases (CO, H2S, PH3, SO2, and HCN)   Order a copy of this article
    by Reshma Khatun, Mohammad Tanvir Ahmed, Shariful Islam, Md. Kamal Hossain, Md. Abul Hossain, Farid Ahmed 
    Abstract: Abstract: The adsorption of various toxic gases (CO, H2S, PH3, SO2, and HCN) on a two-dimensional (2D) Boron-Carbon-Nitride (BCN) sheet has been investigated using the first-principles calculation based on Density Functional Theory (DFT). The corresponding adsorption structure, adsorption energy, density of states (DOS), and the band structures have been studied. Here, we observed better stability of the BCN structure. DOS and band structures show the conducting property of the BCN sheet. The electronic and adsorption properties reveal the applications of the BCN sheet in sensing of the mentioned molecules.
    Keywords: Keywords: Sensor; nanosheet; DFT; BCN; toxic gas.

  • An accurate detection method for randomly distributed welding slags using an improved Yolo v3 network   Order a copy of this article
    by Qiuping Tu, Hongdi Liu, Chao Qu, Linli Tian, Dahu Zhu 
    Abstract: Irregular welding slag spatters during welding of the car body are considered as extremely unavoidable defects. Detecting these tiny defects exhibiting properties in position and number is a challenging task. In this paper, a novel computational framework by modifying the structure of the Yolo v3 network is developed to accurately detect the randomly distributed welding slags. The improved Yolo v3 is mainly obtained by modifying the Darknet-53 structure and adding 104
    Keywords: defect detection; welding slags; Yolo v3; Darknet53; recall rate.

  • The effect of ultrasonic shot peening on the fatigue life of alloy materials: a review   Order a copy of this article
    by Yun Chen, Sen Deng, Chao Zhu, Kaixiong Hu, Fei Yin 
    Abstract: It is more and more widespread to introduce nano-structured grains on the surface of alloys to improve their strength. One of the technologies to achieve this is the ultrasonic shot peening (USP) technique, which has attracted special attention. With this technology, uniform nano-structured grains can be formed on the surface and compressive residual stress can be developed that can improve the fatigue life. However, pits will be formed during the USP process, which will cause stress concentration and lower the fatigue life. This article reviews the effects of ultrasonic shot peening processing parameters on the evolution of the surface morphology, microstructure and residual stress. A finite element simulation based on the velocity model was established to simulate the impact of the USP processing on the fatigue performance.
    Keywords: ultrasonic shot peening; nano grains; stress concentration factor; USP processing parameters; finite element simulation.

  • Research progress on hot stamping theory and technology of aluminum alloy sheets   Order a copy of this article
    by Yanli Song, Jue Lu, Lin Hua, Chuanchuan Hao, Xiang Dong 
    Abstract: Aluminum alloy is the most potential lightweight material, which has been widely used in aviation, aerospace, automobile, high-speed rail and so on. Advanced forming and performance strengthening methods of complex thin-walled aluminum alloy components have been the focus of the international research. In this paper, latest research progress in the field of forming and performance strengthening of aluminum alloy sheets and components is reviewed, including isothermal tensile deformation behavior, constitutive equations, processing maps, friction and wear behavior at high temperature, and the mold and equipment for forming aluminum alloy sheet are also reviewed. Then the technical difficulties and development trend of aluminum alloy forming manufacturing are discussed.

  • Design of gating system for propeller casting through melt flow simulation
    by Amir Hosein Riazi, Seyed Mohammad Ali Boutorabi, Mohammad-Reza Aboutalebi, Mohsen Ostad Shabani 
    Abstract: Marine propellers have a complex geometry and uneven thickness, which causes severe and unpredictable problems during the casting process. Designing a proper gating system leads to the production of clean and sound castings. In this paper, a computer modeling study was carried out for casting of a marine propeller using a commercially available software package was used to explore the improvement of filling systems based on the relatively new concepts of avoiding entrainment of air bubbles and oxides by avoiding surface turbulence. In the simulation process, bottom-pour and top-pour designs were considered, which were examined in 7 trials. Since a critical velocity of 0.5 m/s is required to produce clean and sound castings, suitable methods were used to reduce the melt velocity to 0.5 m/s.
