| 3 | Microstructure and Tensile Properties of ZK60 Alloy Fabricated by Simplified Rapid Solidification Powder Metallurgy (S-RS P/M) Process显示文摘This study investigated the microstructures and mechanical properties of ZK60 alloy prepared by a simplified rapid solidification powder metallurgy (RS P/M) processing system (S-RS P/M), which consists of warm press in dry air and hot extrusion. Microstructure characterizations showed that S-RS P/M alloy consisted of magnesium matrix and oxide stringers of~1 μm in width. TEM (transmission electron microscopy) observations illustrated nano-size magnesia particles (10-30 nm) constituted oxide stringer in detail. Due to a relatively higher volume of nano-size magnesia particle produced during S-RS P/M process, 0.2% yield strength of S-RS P/M ZK60 alloy was found to be as high as 382 MPa, which is 10% higher than that of RS P/M alloy. The improvement in mechanical properties is mainly attributed to the combination effects of Orowan mechanism and coefficient of thermal expansion (CTE) mismatch because of the approximately same average grain size. | Zhenya Zhang, Huashun Yu , Shaoqing Wang, Haitao Wang and Guanghui Min Key Laboratory of Liquid Structure and Heredity of Materials, Ministry of Education, Shandong University, Jinan 250061, China | 2010 | Journal of Materials Science & Technology2010，26，2： | 5 |
| 4 | Al-Si/Al_2O_3 in situ composite prepared by displacement reaction of CuO/Al system显示文摘Al2O3 particle-reinforced ZL109 composite was prepared by in situ reaction between CuO and Al.The microstructure was observed by means of OM,SEM and TEM.The Al2O3 particles in sub-micron sizes distribute uniformly in the matrix,and the Cu displaced from the in situ reaction forms net-like alloy phases with other alloy elements.The hardness and the tensile strength of the composites at room temperature have a slight increase as compared to that of the matrix.However,the tensile strength at 350 ℃ has reached 90.23 MPa,or 16.92 MPa higher than that of the matrix.The mechanism of the reaction in the CuO/Al system was studied by using of differential scanning calorimetry(DSC) and thermodynamic calculation.The reaction between CuO and Al involves two steps.First,CuO reacts with Al to form Cu2O and Al2O3 at the melting temperature of the matrix alloy,and second,Cu2O reacts with Al to form Cu and Al2O3 at a higher temperature.At ZL109 casting temperature of 750-780 ℃,the second step can also take place because of the effect of exothermic reaction of the first step. | Zhang Jing Yu Huashun Chen Hongmei Min Guanghui | 2010 | China Foundry2010，7，1： | 3 |
| 5 | Fabrication of AlN-TiC/Al composites by gas injection processing显示文摘The fabrication of AlN-TiC/Al composites by carbon- and nitrogen-containing gas injection into Al-Mg-Ti melts was studied. It was shown that AlN and TiC particles could be formed by the in situ reaction of mixture gas (N2 + C2H2 + NH3) with Al-Mg-Ti melts. The condition for the formation of AlN was that the treatment temperature must be higher than 1373 K, and the amounts of AlN and TiC increased with the increase of the treatment temperature and the gas injection time. It was considered that AlN was formed by the direct reaction of Al with nitrogen-containing gas at the interface of the gas bubble and the melt. However, the mechanism of TiC formation is a combination mechanism of solution-precipitation and solid-liquid reaction. | YU Huashun CHEN Hongmei MA Rendian MIN Guanghui | 2006 | Rare Metals2006，25，6： | 3 |
| 6 | Microstructural Evolution of Rapidly Solidified ZK60 Powders during Extrusion显示文摘The microstructural evolution of rapidly solidified(RS) ZK60 powders extruded at 250 C was investigated.It was shown that formation of new ultrafine grains took place through continuous dynamic recrystallization(CDRX),accompanied by the perfect bonding of powders via severe plastic deformation.At a low strain level,a well-defined structure made up of equiaxed and elongated subgrains was developed.Simultaneously,the operation of basal and non-basal dislocation slip led to the formation of low-angle dislocation cells(LADC) within the elongated subgrains.With increasing strain,the number and average misorientation of LADC increased,resulting in fragmentation of original elongation subgrains into a finally homogeneous fine-grained structure.Almost full-recrystallized structure with an average grain size of 0.4 μm was finally evolved after large cumulative strain.The results suggested that structural change was connected with thermal strain,where dislocation activities dominated this process. | Zhenya Zhang Huashun Yu Shaoqing Wang Hui Yu Guanghui Min | 2011 | Journal of Materials Science & Technology2011，27，2： | 2 |

| 11 | Effects of composite oxide scale on oxidation resistance of superalloy K273显示文摘A Si-containing K273 superalloy was made using intermediate frequency induction furnace in the study. In the testing of oxidation resistance,the oxidation process of the alloy specimens during the testing at 900℃ for 500 h was examined by oxidation weight gain method.The morphology and composition of the oxide scales were determined using scanning electron microscope(SEM)and X-ray diffraction(XRD),respectively.The effects of the transferring of ions and electrons on the oxidation resistance were further analyzed microscopically by semiconductor oxide models.The results show that the composite oxide scales consist of Cr2O3,SiO2 and spinel- type oxide MCr2O4,with flat and compact structure,and fine grains in uniform distribution.All of these endow the superalloy K273 with strong oxidation resistance.The reason for the powerful oxidation resistance of the composite scale is that the formation process of P+N type semiconductor oxide enables to consume most of the surplus negative and positive ions in the oxide scales,which makes the number of the mobile ions and electrons dropped enormously,and the transfer rate of them falls heavily.So the oxidation rate of the metal phase in the alloy matrix is reduced significantly. | Wang Haitao Tan Jiwen Chu Zhong Yu Huashun | 2012 | China Foundry2012，9，2： | 1 |

| 16 | Oxidation process of lanthanum hexaboride ceramics显示文摘Oxidation process of lanthanum hexaboride (LaB6) ceramic powder was investigated . The LaB6 powder samples were heated continually from room temperature to 1 473 K at a heating rate of 10 K/min by differential scanning calorimetry. The oxidation tests were conducted at different exposure temperatures. The phases and morphologies of the samples before and after exposure were analyzed by XRD and SEM. It was pointed out that before 1 273 K, LaB6 has high oxidation resistant ability, which was due to that the oxide layer hinders the oxygen diffusion from outer to the surface of LaB6 grains. The oxide layer was composed of the transition phases, which were composed of La2O3 and B2O3 formed from the initial oxidation; when the oxidation temperature exceeded 1 273 K, protective layer was destroyed due to the vaporization of liquid B2O3. Based on the results of X-ray diffraction analysis, oxidation process of LaB6 ceramic powder can be described as follows: Before 1 273 K, lanthanum borate,La(BO2)3 was formed on the surface of samples, then lanthanum oxide (La2O3) and boron oxide (B2O3) were present on the surface of samples oxidized when the temperature reached to 1 473 K. | ZHENG Shuqi, MIN Guanghui, ZOU Zengda , YU Huashun, HAN Jiande , and WANG Weiti School of Materials Science and Engineering, Shandong University, Jinan 250061, China | 2002 | Rare Metals2002，21，2： | 0 |
| 17 | Effect of CuO addition on microstructure and properties of aluminum composites produced by quick spontaneous infiltration process显示文摘Al matrix composites with a high volume fraction of reinforcements were fabricated with a compact of Al-Ti-B4C powder mixtures by quick spontaneous infiltration(QSI) process in an aluminum melt. Given the exothermal nature of the reaction between CuO and Al, a certain amount of CuO addition to the Al-Ti-B4C system dramatically increases the adiabatic temperature and thereby enables the complete combustion reaction in an aluminum melt(about 1,173 K). After the QSI process, the compact fabricated with CuO retains its original shape and the obtained composite exhibits sound microstructure containing reaction products of TiB2, Al3BC and B4C. The formation of such reinforcements when adding CuO contributes to enhancing the properties of the composites that show far superior hardness and elastic modulus of 3.03 GPa and 158.9 GPa, respectively, with lower coefficient of thermal expansion(9.44 ppm?K-1) compared to those with no CuO addition. | Zhang Jingjing Lee Jung-Moo Cho Young-Hee Kim Su-Hyeon Yu Huashun | 2014 | China Foundry2014，11，3： | 0 |
