| 1 | New type of spherical pore Al alloy foam with low porosity and high strength显示文摘A computer system for displacement sensor is developed to obtain the real-time curve of the liquid porosity of molten Al alloy foam. The relationship between the curve of Pl-t and the change of the shape of the cells (spherical, similar spherical and polygonal) in the foaming process is analyzed. The changes of cell diameter and cell wall thickness are studied. And the the controlling methods of a new Al alloy foam with spherical pores, low porosity and high strength are developed on this basis. Also, the stress-strain curve during compressive deforma- tion and energy absorption characteristics are investigated and compared with polygonal pore Al alloy foam with high porosity. | ZOU Yi HE Deping JIANG Jiaqiao | 2004 | Science China Chemistry2004，47，5： | 21 |
| 2 | Changes in porosity of foamed aluminum during solidification显示文摘In order to control the porosity of foamed aluminum, the changes in the porosity of foamed aluminum melt in the processes of foaming and solidification, the distribution of the porosity of foamed aluminum, and the relationship between them were studied. The results indicated that the porosity of foamed aluminum coincides well with the foaming time. | Zhaojin Wu Deping He | 2000 | Chinese Science Bulletin2000，45，18： | 17 |
| 3 | Thermal decomposition kinetics of titanium hydride and Al alloy melt foaming process显示文摘A temperature programmed decomposition (TPD) apparatus with metal tube struc- ture, in which Ar is used as the carrier gas, is established and the TPD spectrum of titanium hy- dride is acquired. Using consulting table method (CTM), spectrum superposition method (SSM) and differential spectrum technique, TPD spectrum of titanium hydride is separated and a set of thermal decomposition kinetics equations are acquired. According to these equations, the rela- tionship between decomposition quantity and time for titanium hydride at the temperature of 940 K is obtained and the result well coincides with the Al alloy melt foaming process. | YANG Donghui*1, HE Deping*1& YANG Shangrun*2 1.

| 5 | Spherical foam growth in Al alloy melt显示文摘Due to the demand of high-tech Al alloy foam with spherical pores, high strength and high energy-absorption capacity has become one of the research foci. The aim of this study is to ascertain the growth regularity of spherical foam in Al alloy melt. Three-dimensional packing model such as face-centered cubic is established to study the spherical foam growth. Theoretical results are compared with experimental ones, and the face-centered cubic model corresponds well with the experiment. It is reasonable to assume that the pores have the same radius, the total pore number keeps unchanged and spherical foam grows with face-centered cubic packing mode. This study presents a useful help to control the average pore radius and film thickness. | SHANG Jintang HE Deping | 2005 | Science China Chemistry2005，48，3： | 6 |
| 6 | The two steps thermal decomposition of titanium hydride and two steps foaming of Al alloy显示文摘Two steps foaming (TSF) technique was proposed to prepare shaped Al alloy foam. Based on the thermal decomposition kinetics equation of titanium hydride, the relationship be-tween two steps thermal decomposition kinetics of titanium hydride and two steps foaming Al alloy melt was studied. Two steps thermal decomposition curve of titanium hydride under in-creasing and constant temperature was calculated respectively. The hydrogen mass needed in the second foaming step was also calculated. Results showed that the hydrogen mass of the second thermal decomposition of titanium hydride is enough for the second foaming step in the condition of as-received Al melt foaming. Experimental and theoretical results indicate that two steps foaming technique can be used to prepare Al alloy foam with high porosity, shaped com-ponents and sandwich with Al alloy foam core. | SHANG Jintang HE Deping | 2005 | Science China Chemistry2005，48，6： | 6 |
| 7 | Fabrication of Open-cell Al Foam Core Sandwich by Vibration Aided Liquid Phase Bonding Method and Its Mechanical Properties显示文摘The open-cell Al foam core sandwiches(AFCSs) were successfully fabricated by using a specially designed Zn-Al-Cu based filler alloy via vibration aided liquid phase bonding method.The effects of the vibration on the bonding seam were investigated and the bonding strength between Al foam core and solid Al alloy face sheet was tested by shearing tests.The results show that vibration can significantly improve the quality of the bonding and the shearing strength of the bonding seam,which implies that this joining method has a good potential in practical applications. | Hui Wang Donghui Yang Siyuan He Deping He | 2010 | Journal of Materials Science & Technology2010，26，5： | 5 |
| 8 | Performance improvement of light-emitting diodes with double superlattices confinement layer显示文摘In this study, the effect of double superlattices on GaN-based blue light-emitting diodes(LEDs) is analyzed numerically. One of the superlattices is composed of InGaN/GaN, which is designed before the multiple quantum wells(MQWs). The other one is AlInGaN/AlGaN, which is inserted between the last QB(quantum barriers) and p-GaN. The crucial characteristics of double superlattices LEDs structure, including the energy band diagrams, carrier concentrations in the active region, light output power, internal quantum efficiency, respectively,were analyzed in detail. The simulation results suggest that compared with the conventional AlGaN electronblocking layer(EBL) LED, the LED with double superlattices has better performance due to the enhancement of electron confinement and the increase of hole injection. The double superlattices can make it easier for the carriers tunneling to the MQWs, especially for the holes. Furthermore, the LED with the double superlattices can effectively suppress the electron overflow out of multiple quantum wells simultaneously. From the result, we argue that output power is enhanced dramatically, and the efficiency droop is substantially mitigated when the double superlattices are used. | Cheng Cheng Yan Lei Zhiqiang Liu Miao He Zhi Li Xiaoyan Yi Junxi Wang Jinmin Li Deping Xiong | 2018 | Journal of Semiconductors2018，39，11： | 1 |
