Effect of Bimodal Quasicrystal Phase on the Dynamic Recrystallization of Mg–Zn–Gd Alloy during High-Pressure Torsion

引用

Acta Metallurgica Sinica(English Letters) 2024年第7期37卷 1128-1134页

作者： Ping Li Shuangwu Xia Junfu dong Liangwei dai Zhicheng Luo Kemin Xue School of Material Science and Engineering Hefei University of TechnologyHefei230009China

The Mg–Zn–Gd alloy with quasicrystal icosahedral phase was processed by high-pressure torsion (HPT). The effect of bimodal I-phase on the dynamic recrystallization was analyzed by transmission electron microscopy. The results showed that the block I-phase can stimulate obvious particle-stimulated nucleation and dynamic recrystallization (DRX) grains were preferentially formed after HPT for 5 turns, while the granular I-phase only promoted the generation of sub-grains. The orientation relationship was determined as twofold//[1210] and fivefold//(0002)_(Mg). Moreover, after HPT for 9 turns, the DRX grains induced by block I-phase appeared to grow up and coarsened. Compared with block I-phase, the grains induced by granular I-phase presented much smaller size and distributed more homogeneous due to the strong pinning effect.

Effect of synergistic urea by nitrification inhibitor coated with resin on wheat growth and soil nitrogen supply

引用

Pedosphere 2024年第5期34卷 960-970页

作者： Yaru GE Yu LI Yuanjie dong Mingrong HE Xinglong dai College of Resources and Environment Shandong Agricultural University Agronomy College Shandong Agricultural University

Combining nitrification inhibitor and urea can improve crop yield and nitrogen (N) use efficiency (NUE). However, the inhibitor easily gets inactivated in soil, making it difficult to achieve the desired effect. To develop a synergistic urea for increasing the inhibitor action time, soil N supply, and wheat growth,dicyandiamide (DCD) was coated after granulation with epoxy resin and then mixed with urea to develop new resin-coated DCD (RCD) synergistic *** electron microscopy (SEM) and hydrostatic release tests were used to evaluate the membrane microstructure and the controlled-release performance of RCD. Five fertilization treatments were set up in the field:zero-N control (CK), urea (U), urea+common DCD particles (SUD1), urea+RCD (SUD2),and urea+both common DCD particles and RCD (3:7, weight/weight)(SUD3) to investigate the effects of the DCD synergistic urea on wheat growth, yield,and NUE and soil available N content. The SEM results showed that RCD had a complete coating, smooth surface, and small and rugged channels for DCD release in the profile. The hydrostatic release test at 25?C showed that the release period of DCD was extended to ten days due to resin coating. In the three DCD synergistic urea treatments, only SUD3 resulted in a significant increase in wheat yield (18.47%) compared with U. The NUE in SUD3 was significantly higher than those in SUD2, U, and SUD1. The treatment SUD3 had higher soil available N content than the other treatments during the key wheat growth stages, while effectively reducing the risk of soil nitrate leaching during wheat maturity. In summary, SUD3, a mixture of urea, DCD particles, and RCD, was the best treatment for significantly increasing wheat growth, yield, and NUE and soil N supply.
