In Situ Synchrotron X-ray Diffraction Investigations of the Nonlinear Deformation Behavior of a Low Modulus β-Type Ti36Nb5Zr Alloy

Metals (2020)

Qingkun Meng Huan Li Kai Wang Shun Guo Fuxiang Wei

The low modulus β-type Ti alloys usually have peculiar deformation behaviors due to their low phase stability. However, the study of the underlying mechanisms is challenging since some physical mechanisms are fully reversible after the release of the load. In this paper, the deformation behavior of a low modulus β-type Ti36Nb5Zr alloy was investigated with the aid of in situ synchrotron X-ray diffraction (SXRD) during tensile loading. The evolution of lattice strains and relative integrated diffraction peak intensities of both the β and α” phases were analyzed to determine the characteristics of the potential deformation mechanisms. Upon loading, the α” diffraction spots appeared at specific azimuth angles of the two-dimensional SXRD patterns due to the <110> fiber texture of original β grains and the selection of favorable martensitic variants. The nonlinear deformation behavior originated from a reversible stress-induced martensitic transformation (SIMT). However, the SIMT contributed a little to the large recoverable strain of over 2.0%, which was dominated by the elastic deformation of the β phase. Various deformation mechanisms were activated successively at different applied strains, including elastic deformation, SIMT and plastic deformation. Our investigations provide in-depth understandings of the deformation mechanisms in β-type Ti alloys with low elastic modulus.

Research on Carbon Peak and Carbon Neutrality Technological Pathways in the Chinese Papermaking Industry

Paper and Biomaterials (2023)

Zaifeng Zhou Fuxiang Wei

Against the backdrop of the dual carbon goals, the papermaking industry in China faces significant pressure to reduce emissions and lower carbon intensity. Based on historical data of energy consumption in the pulp and paper industry in China from 2000 to 2020, this study analyzed the current status of paper production and energy consumption in China. Two methods were employed to predict the growth trend of paper production in China, and three carbon dioxide emission accounting methods were compared. The study used an accounting method based on the industry's overall energy consumption and predicted the carbon dioxide (CO₂) emissions of the Chinese papermaking industry from 2021 to 2060 under three scenarios. The study identified the timing for achieving carbon peak and proposed the measures for carbon neutrality. The results indicated that: (1) the CO₂ emissions of the Chinese papermaking industry in 2020 were 111.98 million tons. (2) Under low-demand, high-demand, and baseline scenarios, the papermaking industry is expected to achieve carbon peak during the "14th Five-Year Plan" period. (3) In 2060, under the three scenarios, CO₂ emissions from the papermaking industry will decrease by 11%-31% compared to the baseline year. However, there will still be emissions of 72-93 million tons, requiring reductions in fossil energy consumption at the source, increasing forestry carbon sequestration and utilization of Carbon Capture, Utilization and Storage (CCUS) technology, and taking measures such as carbon trading to achieve carbon neutrality.

Influence of Al and Ti Alloying and Annealing on the Microstructure and Compressive Properties of Cr-Fe-Ni Medium-Entropy Alloy

Tailin Yang Junjie Feng Yanyan Wang Honglian Deng Xiang Zhang

This research investigates the impact of Al and Ti elements on the formation of self-generated ordered phase in high-entropy alloys, which have been receiving widespread concentration in present times thanks to their remarkable multifunctional properties and wide range of component selection. By adjusting the dual elements of Al and Ti, the study explores the regulation of quantity and distribution of the in-situ self-generated ordered phases in the alloy. The results of the annealing heat treatment process demonstrated that, by adding Al and Ti elements, the Cr-Fe-Ni medium-entropy alloy transfer from BCC phase to BCC+FCC phase and the precipitation of new phases such as B2, L21, and σ. This led to a synergistic impact of second phase strengthening, and also of solid solution strengthening, resulting in improved compressive properties of high-entropy alloy.
