The microstructure, tensile property and wear resistance of 7075 aluminum matrix composite reinforced with TiC particles prepared by in-situ reaction casting were investigated. The effect of TiC reinforcement on wear behavior was analyzed. The wear mechanism was also discussed. A micro-mechanism model of reaction kinetics for synthesis of TiC was acquired. Results show that TiC could increase the tensile and yield strength, but decrease the elongation. Besides, TiC particles improve the property of wear resistance of 7075 aluminum alloy. The wear mechanisms include abrasive wear and adhesive wear in wear test process.

Pouring temperature and time are the most important influencing factors on interfacial reaction during the centrifugal casting. When cast at high temperatures, the crucible becomes brittle and prone to cracking, and shows a low stability. In this paper, we studied the centrifugal casting of Ti-47.5-Al-2.5V-1Cr alloy, and explored the effects of pouring temperature on the interfacial reaction. Castings at 1 600, 1 650, and 1 700 ℃ were obtained by controlling the other parameters constant in the experiments. The microstructure, elemental distribution, thickness of the reaction layer and phase composition of the castings at the interface were studied. The results show that the thickness at the interfacial reaction layer is increased by raising the pouring temperature. The elements in the mold and the matrix were double-diffused and reacted at the interface during the casting process, and formed solid solutions with the precipitation of many new phases such as AlOand TiO. The roughness of interface structure and layer thickness of reaction increase with the rise of temperature, and the interfacial reaction is more intense. There is a minimum layer thickness of the reaction layer that is 80 μm when the temperature is 1 600 ℃.

在非洲猪瘟对我国生猪产业产生巨大冲击的背景下,生猪生产恢复的相关扶持政策主要面向规模化养殖的企业集团,而对农村养殖户的关注较少。该文以行政村村委、兽医对农村散养户生猪养殖的管控和农村散养户自身的防控为主要研究对象,通过梳理对比非洲猪瘟疫情在国内的传播过程以及各级政府的防控政策,选取广西恭城县A村的防控现状进行实际调研,研究农村地区防控中的问题与对策。结果发现:①上级政府及其政策对规模化养殖关注和扶持较多,对农村散养关注较少;②农村疫情防控力量薄弱;③村委在政策执行中存在惰性;④兽医本身履职能力不够,履职态度不端正;⑤农村养殖户信息获取不足。针对上述问题,该文提出了解决问题的办法和建议。
