Intermetallic gamma titanium aluminides display attractive engineering properties at high temperatures of up to 750 °C. To date, they have been used in low-pressure turbine blades and turbocharger rotors in advanced aircraft and automotive engines. This review summarizes the fundamental information of the Ti–Al system. After providing the development of $\gamma$TiAl alloys, typical phases, microstructures and their characteristics in TiAl alloys, the paper focuses on the effects of alloying elements on the phase boundary shifting, stabilizing effects and strengthening mechanism. The relationships between chemical additions, microstructure evolution and mechanical properties of the alloy are discussed. In parallel, the processing technologies and the common heat treatment methods are described in detail, both of which are applied to optimize the mechanical properties via adjusting microstructures. On this basis, the effects from chemical composition, processing technologies and heat treatments on microstructure, which controls the mechanical properties, can be obtained. It has a certain guiding significance for tailoring the microstructures to gain desired mechanical properties.

One demand imposed by the global market is the possession of adequate soft skills, a challenge commonly faced by STEM (science, technology, engineering, and mathematics) graduates. This challenge is particularly prominent in China, which produces millions of STEM graduates annually. Consequently, there is a pressing need to develop and research programs facilitating the acquisition of soft skills, with a specific focus on teamwork, among Chinese engineers. To this end, we created a team-based project as part of a semester-long scientific English communication course at a Sino–foreign STEM university in China. The project aimed at fostering valuable soft skills through active learning, including teamwork, communication, and collaboration. In this report, we examine written reflections by students, aiming to assess their perceptions of soft skill development and overall experience resulting from their participation in the team-based project. Our results show the self-reflected soft skills development was considerable, and, unexpectedly, a noteworthy outcome of the project was the significant development of interpersonal connections, resulting in a positive experience and friendship development. Consequently, the findings of this study shed light on how teamwork can foster soft skills and friendship development, the latter often referred to as relationship development, another soft skill in the 21st century.

Curiosity and question-asking are at the heart of science and engineering education. However, question-asking can be difficult for students due to several factors, including fear, language barriers, and cultural norms. This is especially true among Chinese students, who represent a growing number of upcoming engineers. To address this, in this case study from a university teaching reform project, we investigate the perceptions of curiosity and question-asking among Chinese science, technology, engineering, and mathematics (STEM) undergraduate students following a newly developed semester-long project in a second-year communications course at a recently established Sino-foreign engineering school in China. In this period, students engaged in project-based learning centered around Nobel Prize-winning research, allowing them to explore the driving questions behind groundbreaking discoveries. Through a combination of qualitative analyses from students’ personal reflections as well as from a post-survey, the study examines students’ perceptions of curiosity and question-asking, the influence of gender on these skills, and the role of failure and perseverance in scientific inquiry. Findings indicate that the project increased students’ curiosity and improved their confidence in asking questions while providing insights into gender differences. Moreover, students were inspired by the curiosity of the Nobel Laureates, by the “simplicity” of the questions asked, and by the great importance of tenacity, passion, and learning from mistakes.

Using two fencing swords manufactured in Europe and China, we investigated the typical materials used for fencing blades and compared the experimental results with the nominal compositions of a variety of steels. We found that spring steels and maraging steels were the primary metals used in fencing blades. The review then provides an overview of the chemical compositions, heat treatment processes, microstructures and associated mechanical properties of these materials. By combining the requirements for the safety of athletes, mechanical behaviors of different steels, and production costs for industry, we introduced possible directions for the heat treatments and processing methods that have the potential to enhance performance and overcome the limitations of previous materials. In addition, an ultra-strong steel, Fe-9.95Mn-0.44C-1.87Al-0.67V which could be a promising new candidate in this area, was recommended. Finally, we suggested that successful cooperation between manufacturers and researchers is necessary to reach the various requirements of fencing blades to meet the growing popularity of fencing in China.
