Relationship between high angle grain boundaries and hardness after γ→α transformation

B.B. Wu, Z. Q. Wang, X. L. Wang, Jingxiao Zhao et autres

This study is devoted to establish the relationship between high angle grain boundaries (HAGBs) and hardness from crystallography and provide reference for improving the hardenability of high strength ultra-heavy plate steel. The starting temperature during γ→α phase transformation was significantly decreased with …

Retesting the existence, relativity and convergence of energy curse: An empirical test based on the provincial panel data analysis in China

Qin Xi, Yusen Xu, Qianqian Lu, X. L. Wang

An index, Resource Curse Intensity (RCI), is proposed to evaluate the degree of deviation between energy endowment and economic growth by taking national economic conditions into account for the energy system. The RCI is intended to provide a quantitative measure of what …

Retained austenite stabilisation in low carbon high silicon steel during isothermal holding

Z.J. Xie, Z. F. Liu, R.D.K. Misra, Chengjia Shang et autres

We elucidate here the role of isothermal hold temperature of 300–500°C after intercritical annealing at 760°C on bainitic transformation and in governing the stabilisation of retained austenite in a 0.23C-1.35Si-1.82Mn steel. A critical analysis was attempted to explain the observations using displacive …

Investigation of the microstructure and toughness of 550 MPa grade pipeline after the hot-bending process

X. L. Wang, Yu-Ting Tsai, Jer‐Ren Yang, Chengjia Shang et autres

In this work, the effects of the hot-bending process on the microstructure and low temperature (−40°C) toughness of weld metal of pipeline K65 (the highest grade of the Russian natural gas pipeline) were studied. The weld metal from the longitudinally submerged arc …
