文摘The complex grain fragmentation mechanisms of coarse grains in titanium alloys under multi-directional forging(MDF)directly influence the optimization and control of primary hot working processes.This study conducted MDF experiments onβ-phase as-cast Ti-6554 alloy and simulated non-uniform deformation during cyclic multi-directional compression through macro-and micro-deformation modeling.The results revealed that friction and surface cooling caused low strain and tensile stress concentration at billet edges,leading to mixed grain structures.In contrast,high strain and triaxial compressive stress at billet centers facilitated uniform grain refinement.After 14 compressions and 4 intermediate reheating processes,coarse grains of the billet were refined from 2-5 mm to 0.25-0.50 mm,achieving uniform grain sizes across different regions.For the first time,the orientation evolution of grains with different morphologies during multi-directional compressions was visualized microscopically.Columnar grains were found to be more easily subdivided than equiaxed grains due to local strain accumulation.Under cumulative compressions,grain orientations gradually rotated from uniform to random,driving continuous dynamic recrystallization(CDRX).Slip system interactions and concentrated misorientation led to the formation and extension of transition and shear bands,inducing grain fragmentation dominated by transgranular subdivided CDRX.Smooth grain boundaries transformed into serrated ones after multiple passes,providing additional nucleation sites for discontinuous dynamic recrystallization(DDRX)and facilitating boundary expand CDRX.The interaction of diverse DRX mechanisms was the fundamental cause of grain refinement.This study clarified the principles of refining and homogenizing millimeter-grade coarse grains under increasing forging strain,offering valuable insights for the development of primary hot processing techniques for as-castβtitanium alloys.

文摘The superplasticity of the Mg−8.59Gd−3.85Y−1.14Zn−0.49Zr alloy was investigated before and after multi-directional forging(MDF)and the mechanisms affecting superplastic deformation were analyzed.The results indicate that after MDF at a temperature of 350℃and strain rates of 0.1 and 0.01 s^(−1)(1-MDFed and 2-MDFed),the superplasticity of the alloy can be significantly improved.The elongations of the MDFed alloys exceed 400%under the strain rate of 6.06×10^(−4)s^(−1)and temperatures of 350,375,and 400℃,and reach the maximum values of 766%(1-MDFed)and 693%(2-MDFed)at 375℃.The grain boundary sliding of the MDFed alloy is sufficient,and the energy barrier of deformation decreases.Theβphase limits the grain growth and promotes dynamic recrystallization,maintaining the stability of the fine-grained structure during superplastic deformation.Several Y-rich phases nucleate in the high-strain region(i.e.,the final fracture region)at high temperatures,accelerating the fracture of the specimen.

文摘This study examined the effects of design thinking pedagogy on undergraduates’career decision-making selfefficacy and employability in career education.Using a quasi-experimental design,Chinese college students(N=93)were participants in two wings.The experimental group(n=47)received the design thinking pedagogy,while the control group(n=46)followed the regularly teacher-centered method.The students completed the career decision-making self-efficacy scale and employability scale before and after the intervention.Independent samples t-test results showed that design thinking pedagogy significantly improves students’career decision-making self-efficacy and employability.The ANCOVA results showed that the pretest scores of career decision-making self-efficacy and employability had no significant association with the experimental intervention.There was no interaction between the treatment and pretest scores.It would seem that experimental design thinking pedagogy implemented in career guidance courses has little effect compared to the usual course presentation.Nonetheless,prospects for the implementation of design thinking-guided learning activities to support interdisciplinary learning for improved higher education and career development outcomes need further exploration.
文摘Under the tide of economic globalization,college English teaching should not only focus on the improvement of language ability,but also on the cultivation of students’critical thinking ability.This paper takes the integration of language learning and critical thinking ability as the breakthrough point,explores the college English teaching mode under the background of the integration of the two,analyzes the current situation and disadvantages of the separation of the two in the current teaching,and puts forward the integration path from the aspects of curriculum design,teacher training,evaluation system,and so on.With the help of activities such as creating real language situations,carrying out debates and critical reading,it helps students strengthen the improvement of logical analysis and critical thinking ability in their gradual learning,realize the coordinated development of language learning and critical thinking ability,and cultivate compound talents with both language literacy and critical thinking ability for the society.

文摘We demonstrate a multi-method approach towards discovering and structuring sustainability transition knowl edge in marginalized mountain regions.By employing reflective thinking,artificial intelligence(AI)-powered text summarization and text mining,we synthesize experts’narratives on sustainable development challenges and solutions in Kardüz Upland,Türkiye.We then analyze their alignment with the UN Sustainable Development Goals(SDGs)using document embedding.Investment in infrastructure,education,and resilient socio-ecological systems emerged as priority sectors to combat poor infrastructure,geographic isolation,climate change,poverty,depopulation,unemployment,low education levels,and inadequate social services.The narratives were closest in substance to SDG 1,3,and 11.Social dimensions of sustainability were more pronounced than environmental dimensions.The presented approach supports policymakers in organizing loosely structured sustainability tran sition knowledge and fragmented data corpora,while also advancing AI applications for designing and planning sustainable development policies at the regional level.

文摘This study explores the integration path of ideological and political education in the course Design Thinking and Expression of environmental art design,aiming to enhance students’innovative thinking,social responsibility,and awareness of sustainable development.Based on the core philosophy of design thinking(people-oriented,problem-solving,and interdisciplinary collaboration)and the elements of ideological and political education in courses(moral education,cultural confidence,sustainable development,and social equity),the study proposes implementation paths for optimizing course objectives,adjusting course content,innovating teaching methods,and optimizing the evaluation system.Through project-based learning,situational teaching,and interdisciplinary collaboration,combined with practical cases such as historical district renewal,environmental design for rural revitalization,and green commercial space design,it has been verified that the effective integration of ideological and political elements in courses can enhance students’cultural identity,sense of social responsibility,and design innovation ability.This study provides theoretical support and practical demonstration for the ideological and political reform of environmental art design courses.In the future,interdisciplinary collaboration can be further deepened,social practice applications can be expanded,the evaluation system can be improved,and the systematic development of ideological and political courses can be promoted.
文摘From the perspective of Xiang thinking(象思维imagery thinking),the application of Wu Xing(五行five elements)in traditional Chinese medicine(TCM)provides a reasonable cognitive model.Wu Xing with the earth in the center(中土五行)helps TCM establish extensive connections between the human body and the universe,while Wu Xing in the generating and conquering cycles(生克五行)incorporates everything into a systematic thinking framework through complex dialectical relationships,becoming an ideal cognitive tool for TCM diagnosis and treatment.In essence,Wu Xing represents an upgrade of yin-yang dialectical thinking into a two-dimensional Xiang thinking diagram,possessing powerful explanatory capabilities.When faced with complex life systems,Wu Xing provides TCM with a theoretical framework,and TCM,in turn,offers a practical application for Wu Xing.
