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 Articles will not be published until the final proofs are validated by their authors.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.

  • Prediction on phase evolution during cooling of plain C-Mn steel in solid state: a numerical study   Order a copy of this article
    by Amit Kumar Hazra, Md. Basiruddin Sk, Himadri Chattopadhyay, Nilkanta Barman 
    Abstract: This study presents the solid-phase transformation of a plain C-Mn steel by modelling heat transfer during its cooling. The governing equation is discretised and solved numerically. The CCT of the material is modelled to identify phases in transformation. The sum of time steps presents the total cooling time. In a time-step, isothermal transformation is considered using the Avrami equation, and the overall transformation is subsequently predicted. A real-time phase evolution is evaluated, along with temperature distribution and cooling rate in this study. The present prediction is validated with existing literature under different cooling rates. At a cooling rate of 3.33 C/s, austenite transforms into 79% ferrite in 100s, 4.8% bainite in 15s, and 16% pearlite in 33s. A good agreement is found with the existing experiments. The parametric study indicates that as the cooling rate increases, the ferrite fraction decreases, the bainite fraction increases, and the pearlite fraction remains constant.

  • Precise control of low-pressure vacuum carbonitriding in shallow layers of 16Cr3NiWMoVNbE steel   Order a copy of this article
    by Liu Mingyue, Mu Yanan, Wang Guangchao 
    Abstract: As a commonly employed carburising gear steel, 16Cr3NiWMoVNbE steel has received relatively limited research attention in the context of shallow carbonitriding. Traditional controlled atmosphere carbonitriding (CACN) struggles to achieve precise control over the thickness of shallow layers, ensure consistent high-quality layers, and exhibits a steep carbon concentration gradient, restricting its application in high-performance aerospace gears. In this study, we conducted a comparative analysis of CACN and low-pressure vacuum carbonitriding (LPCN) technologies, investigating their effects on the characteristics of the diffusion layer. Research findings indicate that LPCN can achieve finely dispersed carbides on the materials surface and exhibits a gentle hardness gradient transition from the carbonitrided layer into the substrate with increasing depth. Moreover, LPCN can accurately control the depth of the diffusion layer within 0.35 mm, thereby demonstrating superior carbonitriding quality control and diffusion layer thickness management under shallow layer conditions compared to CACN technology.
    Keywords: 16Cr3NiWMoVNbE steel; press quenching; low-pressure vacuum carbonitriding; precise control; aviation gears.
