HAZ effects in hot-rolled dual-phase steel during flash butt welding of wheel rims

Han, Jian; Zhu, Lisong; Wang, Jun; Zhang, Caidong; Sun, Li; Zhang, Zhigiang; Ma, Cheng; Jiang, Zhengyi; Linton, Valerie (Springer, 2023-09-29)

The embrittlement and softening behavior in simulated heat-affected zones (HAZ) of a newly designed dual-phase DP680 steel for wheel rim applications with different flash allowances were investigated to determine weldability, ...
Optimising two-stage vacuum heat treatment for a high-strength micro-alloyed steel in railway spring clip application: impact on microstructure and mechanical performance

Lu, Yao; Wang, Jun; Pan, Di; Han, Jian; Zhu, Lisong; Diao, Chenglei; Han, Jingtao; Jiang, Zhengyi (MDPI, 2023-07-10)

The heat treatment process is a vital step for manufacturing high-speed railway spring fasteners. In this study, orthogonal experiments were carried out to obtain reliable optimised heat treatment parameters through a ...
Physical simulation and numerical simulation of flash butt welding for innovative dual phase steel DP590: a comparative study

Song, Jingwen; Zhu, Lisong; Wang, Jun; Lu, Yao; Ma, Cheng; Han, Jian; Jiang, Zhengyi (MDPI, 2023-05-03)

In this study, the microstructure and performance of newly designed dual-phase steel (DP590) after joining by flash butt welding (FBW) for vehicle wheel rims was analysed and compared by two simulations, i.e., physical ...
Strain hardening and strengthening mechanism of laser melting deposition (LMD) additively manufactured FeCoCrNiAl0.5 high-entropy alloy

Zhu, Lisong; Geng, Keping; Wang, Jun; Sun, Da; Shan, Mengdie; Lu, Yao; Zhang, Xuesong; Cai, Yangchuan; Han, Jian; Jiang, Zhengyi (Elsevier, 2022-10-05)

In order to develop the high-entropy alloy (HEA) with low cost and excellent mechanical properties for structural applications, the FeCoCrNiAl0.5 HEA has been fabricated by laser melting deposition, one of the advanced ...
