| 1 | 关于6A02铝合金板热成型-整体淬火工艺的实验研究显示文摘作为重要的轻质结构材料,铝合金已广泛用于汽车和航空工业。主要用来制造具有高强度,精确尺寸的零件。本文中开发了一种特殊装置,用来研究冷轧6A02铝合金板热成型-整体淬火工艺。用测维氏硬度和拉伸试验来反映强化效果。用扫描电镜(SEM)透射电镜(TEM)、和电子背散射衍射进行显微检测来阐明强化机理。结果表明,随着固溶时间(<50 min)延长维氏硬度增大,强化效应越大。成型零件的维氏硬度能从冷轧态的73 HV或热成型-整体淬火工艺(在520℃固溶50 min,以50°C/s冷却,以160°C/10 h时效)加热后的40 HV增加到106.5 HV。相应的拉伸强度和屈服强度分别是315.6 MPa和253.6 MPa。强化相是未成形的弥散的GP区,约5 nm大小。轧制态的可热处理的铝合金板通常直接用热成型-整体淬火工艺不作任何前处理。 | Fan Xiaobo He Zhubin Yuan Shijian Zheng Kailun | 2013 | 热处理技术与装备2013，34，6： | 19 |
| 2 | High-efficiency forming processes for complex thin-walled titanium alloys components: state-of-the-art and perspectives显示文摘Complex thin-walled titanium alloy components play a key role in the aircraft,aerospace and marine industries,offering the advantages of reduced weight and increased thermal resistance.The geometrical complexity,dimensional accuracy and in-service properties are essential to fulfill the high-performance standards required in new transportation systems,which brings new challenges to titanium alloy forming technologies.Traditional forming processes,such as superplastic forming or hot pressing,cannot meet all demands of modern applications due to their limited properties,low productivity and high cost.This has encouraged industry and research groups to develop novel high-efficiency forming processes.Hot gas pressure forming and hot stamping-quenching technologies have been developed for the manufacture of tubular and panel components,and are believed to be the cut-edge processes guaranteeing dimensional accuracy,microstructure and mechanical properties.This article intends to provide a critical review of high-efficiency titanium alloy forming processes,concentrating on latest investigations of controlling dimensional accuracy,microstructure and properties.The advantages and limitations of individual forming process are comprehensively analyzed,through which,future research trends of high-efficiency forming are identified including trends in process integration,processing window design,full cycle and multi-objective optimization.This review aims to provide a guide for researchers and process designers on the manufacture of thin-walled titanium alloy components whilst achieving high dimensional accuracy and satisfying performance properties with high efficiency and low cost. | Kehuan Wang Liliang Wang Kailun Zheng Zhubin He Denis J Politis Gang Liu Shijian Yuan | 2020 | International Journal of Extreme Manufacturing2020，2，3： | 10 |

Some experiments have been done, and the experimental results show that this technique is feasible to form polycarbonate part. But the wall thickness distribution of the bulged specimen by this method is not so even. | Zhenxiou HOU Bugeng TENG Jun LU Zhubin HE and Zhongren WANG School of Materials Science and Engineering, Harbin institute of Technology, Harbin 150001, China | 2001 | Journal of Materials Science & Technology2001，17，1： | 2 |

| 9 | Using video imagery to reconstruct the 3D intertidal terrain along a beach with multiple cusps显示文摘A high-frequency,high-resolution shore-based video monitoring system(VMS)was installed on a macrotidal(tidal amplitude>4 m)beach with multiple cusps along the Quanzhou coast,China.Herein,we propose a video imagery-based method that is coupled with waterline and water level observations to reconstruct the terrain of the intertidal zone over one tidal cycle.Furthermore,the beach cusp system(BCS)was precisely processed and embedded into the digital elevation model(DEM)to more effectively express the microrelief and detailed characteristics of the intertidal zone.During a field experiment conducted in January 2022,the reconstructed DEM was deemed satisfactory.The DEM was verified by RTK-GPS and had an average vertical root mean square error along corresponding RTK-GPS-derived intertidal profiles and corresponding BCS points of 0.134 m and 0.065 m,respectively.The results suggest that VMSs are an effective tool for investigating coastal geomorphic processes. | Feng Cai Hang Yin Hongshuai Qi Jixiang Zheng Yuwu Jiang Zhubin Cao Yanyu He | 2023 | Acta Oceanologica Sinica2023，42，7： | 0 |
| 10 | On the Construction of Mohr Stress Circle and a Graphic Method in Representing the Stress Components on Different Oblique Planes显示文摘The Mohr stress circle for three-dimensional stress is usually determined by equations,which is lack of intuitionistic meanings and difficult to understand. In this paper, the construction of Mohr stress circle is illustrated directly by numerical method. The shortcoming of Mohr stress circle in representing the stress components on different oblique planes for three-dimensional stress is analyzed. A three-dimensional figure is given to describe the variation of normal and shear stress on different oblique planes at one point for the first time. | Zhubin He Z. R.

| 11 | Formability evaluation of AZ31B extruded tube for hydroforming process显示文摘Hydroforming of magnesium and aluminum alloy tube at elevated temperature is becoming a very promising method to manufacture light-weight hollow components.Uniaxial tensile test and hydrobulging test were used to investigate the formability of AZ31B magnesium tube at different temperatures.The tube was manufactured by porthole die extrusion.Results show that as temperature increase,the tension formability along the extrusion direction measured by tensile test increases significantly,whereas the maximum hydrobulging ratio measured by hydrobulging test does not change accordingly.This anisotropy character of the tube,i.e.,different properties in axial direction and hoop direction,is mainly dependant on the extrusion process.In addition,there exists several weld lines along the extrusion direction.These weld lines will become the weakest positions when formed at elevated temperature,and will consequently decrease the formability of the tube during hydroforming process. | HE Zhubin,LIU Gang,YUAN Shijian,and LIANG Yingchun School of Materials Science & Engineering,Harbin Institute of Technology,Harbin 150001,China | 2007 | Rare Metals2007，26，S1： | 0 |
| 12 | Effect of Loading Paths on Hydroforming Tubular Square Components显示文摘The influence of loading path on tube hydroforming process is discussed in this paper with finiteelement simulation. Four different loading paths are utilized in simulating the forming process of square tubular component with hydroforming and the result of different loading path is presented. Among the result. the thickness distribution of bilinear loading path is the most uniform one. It shows that the increase of punch displacement in the stage of high pressure is beneficial to the forming of component for optimized Stress condition. | Hongyang LI Shijian YUAN Kun DAI Lihui LANG Xiaosong WANG Zhubin HE and Zhongren WANG School of Materials Science and Engineering, Harbin institute of Technology, Harbin 150001, China | 2001 | Journal of Materials Science & Technology2001，17，1： | 0 |
