| 1 | Continuous unidirectional solidification of QAl9-4 Cu-Al alloy显示文摘A continuous unidirectional solidification equipment with the advantages of electric slag remelting, induction heating, continuous casting and unidirectional solidification was built to study the QAl9 4 Cu Al alloy. The results show that the electro slag induction continuous unidirectional solidification process can be used for the steady continuous unidirectional solidification of QAl9 4, and revitalizes the down pulling continuous unidirectional solidification process; that the temperature distribution in the mold wall reflects that of the molten metal in the mold, thus the temperature distribution in the mold wall can be used to control the electric slag induction continuous unidirectional solidification process; and that the mutual matching of the technological parameters is the key to stabilize the solidification process. | Chang Guowei(常国威) Yuan Junping(袁军平) Wang Zidong(王自东) Wu Chunjing(吴春京) Hu Hanqi(胡汉起) Miao Zhimin(苗治民) | 1999 | 中国有色金属学会会刊:英文版1999，9，3： | 8 |

| 11 | Effect of Process Factors on Microstructure of Semisolid Continuous Casting Billets显示文摘Semisolid continuous casting (SSCC) is a new technology to produce billets for semisolid metal forming (SSMF). The effect of process factors, such as pouring temperature, stirring rate, preheating temperature and thermal conductivity of stirring chamber, on the microstructure of SSCC billets was studied by means of the factorial experimental method. The results show that the microstructure of SSCC billets can be controlled by the above-mentioned four process factors. In order to obtain fine and rounded granular grains in an SSCC billet, the pouring temperature, preheating temperature and stirring rate should be kept in a moderate range, and the thermal conductivity of stirring chamber should be high. The regression equations with the process factors connecting the microstructure was also set up based on experimental data. | Shuming Xing, Qijie Zhai, Hanqi Hu ( Department of Mechanical Engineering, Tsinghua University, Beijing 100084, China School of Material Science and Engineering, Shanghai University, Shanghai 200072, China Material Science and Engineering School, Univer | 2000 | International Journal of Minerals,Metallurgy and Materials2000，14，4： | 1 |

| 14 | A PARAMETER FOR EVALUATING ABILITY OF GRAIN REFINEMENT OF SOLUTE ELEMENTS显示文摘The gradient of the equilibrium melting temperature distribution at the advancing liquid-solidinterface of liquid side was derived.From which,a parameter,H,used for evaluating the abili-ty of grain refinement of solute elements was proposed.Experiments on Al-based alloys showthat the grain size decreases as the value of parameter,H,increases.Such a dependance indi-cates that the parameter H can be used for choosing grain refiner. | HAN Qingyou HU Hanqi | 1989 | Acta Metallurgica Sinica(English Letters)1989，2，8： | 0 |

| 16 | Systemic and single cell level responses to 1 nm size biomaterials demonstrate distinct biological effects revealed by multi-omics atlas显示文摘Although ultra-small nanoclusters(USNCs,<2 nm)have immense application capabilities in biomedicine,the investigation on body-wide organ responses towards USNCs is scant.Here,applying a novel strategy of single-cell mass cytometry combined with Nano Genome Atlas of multi-tissues,we systematically evaluate the interactions between the host and calcium phosphate(CaP)USNCs at the organism level.Combining single-cell mass cytometry,and magnetic luminex assay results,we identify dynamic immune responses to CaP USNCs at the single cell resolution.The innate immune is initially activated and followed by adaptive immune activation,as evidenced by dynamic immune cells proportions.Furthermore,using Nano Genome Atlas of multi-tissues,we uncover CaP USNCs induce stronger activation of the immune responses in the cartilage and subchondral bone among the five local tissues while promote metabolic activities in the liver and kidney.Moreover,based on the immunological response profiles,histological evaluation of major organs and local tissue,and a body-wide transcriptomics,we demonstrate that CaP USNCs are not more hazardous than the Food and Drug Administration-approved CaP nanoparticles after 14 days of injection.Our findings provide valuable information on the future clinical applications of USNCs and introduce an innovative strategy to decipher the whole body response to implants. | Tao Zhang Tingyun Lei Ruojin Yan Bo Zhou Chunmei Fan Yanyan Zhao Shasha Yao Haihua Pan Yangwu Chen Bingbing Wu Yuwei Yang Lijuan Hu Shen Gu Xiaoyi Chen Fangyuan Bao Yu Li Hanqi Xie Ruikang Tang Xiao Chen Zi Yin | 2022 | Bioactive Materials2022，7，12： | 0 |
| 17 | EFFECT OF NITROGEN ON MATRIX STRUCTURE OF GRAY CAST IRON显示文摘Effect of nitrogen on matrix structure of 3 different varieties of gray cast iron,i.e.,sub-eutectic Fe-C-Si,near-eutectic Fe-C-Si and Fe-C-Si-Mn,has been investigated.The eutectie colony structure of gray cast iron may be refined,the pearlite content increasedand the micro-hardness of pearlite and ferrite raised with an addition of nitrogen.The influ-ence of nitrogen on the transformation temperature of the equilibrium and non-equilibriumphases,as well as,the solution of nitrogen in ferrite and cementite seem to be the major rea-sons to strengthening the matrix structure of gray cast iron. | ZHAI Qijie HU Hanqi University of Science and Technology Beijing,China associate professor,Faculty of Foundry,University of Science and Technology Beijing,Beijing 100083,China | 1993 | Acta Metallurgica Sinica(English Letters)1993，6，6： | 0 |
