The density of Ni-Al alloys in both liquid state and solid-liquid coexistence state was measured with a modified pycnometric method. It was found that the density of Ni-Al alloys decreases with increasing temperature and Al concentration in the alloys. The molar volume of liquid Ni-Al binary alloys increases with the increase of temperature and Al concentration. The partial molar volume of Al in Ni-Al binary alloy was calculated approximately. The molar volume of liquid Ni-Al alloy determined in the present work shows a negative deviation from the ideal linear molar volume.

Since Cu-Al powder characteristics have important effects on the preparation of Cu/Al2O3 composite, the apparent activation energy of Al internal oxidation reaction in Cu-Al pre-alloyed powders with different characteristics was calculated in the present investigation. The microstructure and properties of the synthesized Cu/Al2O3 were studied. The results show that high-energy milling can obviously promote internal oxidation of Al in Cu-Al powders in the same solid solubility. At the same milling conditions and internal oxidation parameters, the solid solution of Al in Cu either in low or high amount will result in the poor microstructure and properties of the Cu/Al2O3 composite. Subsequently, when high-energy milling and internal oxidation are synchronously used to prepare the Cu/Al2O3 composite, there should be an appropriate solubility and milling effect for the pre-alloyed powders.

Commentaries by Philip W.T. Pong, Nongyue He, S.D. Liang, Tao Song, Yuri Gaididei and Sergey Volkov and Alexander Y. Grosberg on my review article (Pang, 2011 [1]) are answered. The validity of Davydov's mechanism of bio-energy transport, the completeness of theory, outstanding problems, the normalization and validity of wave function of the system in Pang' model as well as other related problems are elucidated in detail.

A recent comment on a previously published paper addressed the invalid explanation of the off diagonal interdiflusion coefficients of the beta-Ni(Al,Cr) phase in the Ni-Cr-Al system according to the symmetric property of the thermodynamic matrix. In this paper, the experimental data presented by Hou et al. was reanalyzed and the interdiffusion coefficient matrix was estimated again. The results of the analysis have been discussed in terms of a brief reply to the comments of Liu and Liang. (C) 2010 Acta Materialia Inc. Published by Elsevier Ltd. All rights reserved.

对NiTi形状记忆合金纤维拔出的力学模型进行了探讨.在恒温状态下,考虑纤维和基体间的界面摩擦力,分别用两种本构理论,即Tanaka的指数模型和C.Liang的余弦模型,讨论了形状记忆合金纤维在变轴力作用下的拉伸问题.推导了形状记忆合金纤维拔出量的表达式,并给出数值计算结果.由指数模型和余弦模型得到的结果非常吻合,证明了这种理论方法是正确的.

阐述了预测聚丙烯(PP)/无机粒子复合材料弹性模量的复合法则、 Eistein方程及其修正、Kerner方程、Liang方程.从结构因素方面分析了弹性模量的影响因素.分析表明:无机粒子的粒径越小、分布越合理,其填充PP复合材料的弹性模量越大;与球形、方形等其它粒子相比,长径比较大的薄片状无机粒子具有更强的增强复合材料弹性模量的能力;复合材料的弹性模量随无机粒子含量的增加而提高;提高无机粒子-PP树脂的界面黏结强度以及改善无机粒子在树脂中的分散状态可以提高复合材料的弹性模量.最后指出,影响因素的定量表征和多因素分析是今后的主要研究方向.
