| 3 | Range and similarity of hollow cathode discharge in argon显示文摘Hollow cathode discharge and micro-hollow cathode discharge have numerous applications in the fields of industry,medical treatment,environmental protection,and analytical chemistry.However,many of them lack the typical features of hollow cathode mode,especially the applications at atmospheric pressure.In order to investigate the underlying basic science of hollow cathode discharge,the hollow cathode discharge in argon was studied by experiments.The range for the operation of the hollow cathode mode in the argon-aluminum device was quantitatively determined to be from 0.8 to 4 Torr cm,no matter how small the cathode cavity is.The atmospheric pressure operation of the hollow cathode mode was realised with the aluminum cathode of a 50μm cavity.The hollow cathode discharges were consistent with Townsend similarity law when the anode was very close to the cathode and the value of p·D was chosen at the lower limit of the range for hollow cathode mode.In contrast,if the anode was moved a little bit far from the cathode and the value of p D was significantly increased,the results followed Allis-White scaling law.The reason for the deviation of Allis-White scaling law from Townsend similarity law was given. | Xinyu Hou Xiaobing Zou Yutai Li Lunwei Zhang Xinxin Wang | 2019 | High Voltage2019，4，3： | 0 |
| 4 | The martensitic transition pathway in steel显示文摘The martensitic transformation(MT)lays the foundation for microstructure and performance tailoring of many engineering materials,especially steels,which are with>1.8 billion tons produced per year the most important material class.The atomic-scale migration path is a long-term challenge for MT dur-ing quenching in high-carbon(nitrogen)steels.Here,we provide direct evidence of(11^(-)2)body-centred tetragonal(BCT)twinned martensite in carbon steels by transmission electron microscopy(TEM)investi-gation,and the increase in tetragonality with the C content matches X-ray diffraction(XRD)results.The specific{11^(-)2}_(BCT)twin planes which are related to the elongated c axis provide essential structural details to revisit the migration path of the atoms in MT.Therefore,the face-centred cubic(FCC)to BCT twin to body-centred cubic(BCC)twin transition pathway and its underlying mechanisms are revealed through direct experimental observation and atomistic simulations.Our findings shed new light on the nature of the martensitic transition,thus providing new opportunities for the nanostructural control of metals and alloys. | Tianwei Liu Lunwei Liang Dierk Raabe Lanhong Dai | 2023 | Journal of Materials Science & Technology2023，，3： | 0 |
