IF钢冷轧及再结晶初期微观组织的TEM研究

采用透射电子显微镜对不同压下量和再结晶初期的IF钢样品进行了研究．结果表明：无论是在较小形变量下还是在较大形变量下，形变不均匀性是普遍存在的；冷变形程度不同，织构组分不同，TEM形貌也不同；在再结晶的最初期，冷轧的形变组织演变为近乎等轴的亚晶，优先形成{111}〈uvw〉取向的晶核，晶核逐渐吞并周围的形变基体而长大，最终形成再结晶γ-纤维织构．

Electrochemical C-V Characteristics and Photoluminescence of a-C∶N Films

Amorphous carbon (a-C) films and amorphous carbon films incorporating with the nitrogen (a-C∶N) were deposited on silicon substrates in a radio-frequency driven plasma enhanced chemical vapour deposition system, while the surface electrical properties of films were investigated by electrochemical capacitance-voltage measurements. It was examined the effect of the interface defects on the properties and deduced that the conducting type of a-C∶N films was n-type. Subsequently, a comparative studies of a-C and a-C∶N films were performed by photoluminescence spectra depending on the temperature. With the decrease of the temperature, the main band with peak energy of 2.48 eV in the a-C∶N films was more intense compared with the other three bands caused by amorphous C in the a-C films.

Optimal Layout of Displacement Measurements for Parameter Identification Process in Geomechanics

This paper focuses on designing the optimal layout of measurements for parameter identification problems in geomechanics, which are usually based on in situ displacements. The existence, uniqueness, and stability of the solution from the parameter identification process are thoroughly discussed. Based on these understandings of the problem, two algorithms are proposed as a means of automatically generating the optimal measurements. The validity of these algorithms is first proved by some academic examples, then these algorithms are applied to the Munich subway tunnel project. Good results are observed there.
