Simulation investigation of temperature distribution in large aluminium panel during autoclave age forming process

Xu, Yongqian; Zhan, Lihua

2018 International Journal of Computational Materials Science and Surface Engineering

doi:10.1504/IJCMSSE.2018.095310

In autoclave age forming process (AAF), temperature uniformity in large aluminium panel is one of the most important factors affecting its final shape and performance. In order to predict the temperature field of the panel, a 3D computational fluid dynamics model for autoclave processing of a...

Plastic deformation and microstructure evolution of bearing ring blank during cold rolling process

Deng, Song; Hua, Lin

2018 International Journal of Computational Materials Science and Surface Engineering

doi:10.1504/IJCMSSE.2018.095311

Bearing ring blanks of the high-speed rail bearings, machine tool spindle bearings and wind power bearings have been manufactured through the ring rolling technology. Yet, the plastic deformation and microstructure evolution of bearing ring blanks during the cold rolling process remains unclear....

The austenitic peak stress model of low alloy steel at elevated temperature based on the valence electron theory

Zhou, Xu-dong; Liu, Xiang-ru; Chen, Zheng-yang

2018 International Journal of Computational Materials Science and Surface Engineering

doi:10.1504/IJCMSSE.2018.095319

The traditional method of calculating the high-temperature austenite peak stress empirical model proposed by Sellars and McTegart has been used for 50 years. A new method based on the valence electron theory is presented in three steps. The first step is to calculate the austenitic valence...

Hot deformation behaviour and Hansel-Spittel constitutive model of Cr5 alloy for heavy backup roll

Chen, Xuewen; Wang, Nana; Ma, Xiang; Zhou, Huijun

2018 International Journal of Computational Materials Science and Surface Engineering

doi:10.1504/IJCMSSE.2018.095321

The heavy backup roll is a key component in large steel rolling production line, as it supports the work roll to prevent any excessive deflection. The backup rolls are traditionally produced by large-scale forging process. To accurately describe the high temperature flow behaviour of a newly...

Microstructures evolution and mechanical properties of 5052 aluminium alloy processed by constrained groove pressing

Yang, Kai-huai; Zou, Ze-chang; Zeng, Jian-min; Chen, Wen-zhe

2018 International Journal of Computational Materials Science and Surface Engineering

doi:10.1504/IJCMSSE.2018.095323

Commercial 5052 aluminium alloy sheets were subjected to a severe plastic deformation technique known as constrained groove pressing (CGP) at room temperature. The impact of repeated CGP, upon the microstructure refinement was investigated by polarised optical microscope as well as transmission...

Numerical simulation of residual stress in low temperature colossal carburised layer on austenitic stainless steel

Rong, Dongsong; Jiang, Yong; Gong, Jianming; Peng, Yawei

2018 International Journal of Computational Materials Science and Surface Engineering

doi:10.1504/IJCMSSE.2018.095332

A numerical model is proposed to quantitatively characterise the residual stress evolutions in low temperature colossal carburised layer on austenitic stainless steel. In this model, on the basis of the consideration of concentration and stress dependent carbon diffusivity, prediction of the...

Evaluation of ductile fracture model in bulk forming

Urbánek, Miroslav; Dzugan, Jan; Prantl, Antonin

2018 International Journal of Computational Materials Science and Surface Engineering

doi:10.1504/IJCMSSE.2018.095337

The purpose of this study is to evaluate the parameters of material plasticity and fracture models at room temperature and at rates up to 1 mm/min for steels which are ordinarily used for forging, for instance the 38MnVS6 steel. The behaviour of materials during forming was evaluated and...

Simulation of the bite condition of AZ31 sheet rolling

Liu, Zuyan

2018 International Journal of Computational Materials Science and Surface Engineering

doi:10.1504/IJCMSSE.2018.095339

Sheet rolling is a simple plastic deformation of which, there are many formulas to describe its bite condition, however, there is no rigorous theoretical analysis and result and the applying ranges of these formulas are limited. Although the bite condition is not an important problem in...

Thermo-mechanical analysis in SAE-AISI 1524 carbon steel gas tungsten arc welds

Bonifaz, E.A.

2018 International Journal of Computational Materials Science and Surface Engineering

doi:10.1504/IJCMSSE.2018.095355

A thermo-mechanical analysis was conducted in SAE-AISI 1524 carbon steel gas tungsten arc welds. The sequentially coupled thermal-mechanical finite element modelling approach was used to simulate the thermal and stress evolution during the GTAW process. The analysis procedure was divided into two...
