. It is shown that ion milling is a real universal and promising polishing method for EBSD preparation of almost all materials. There exists a maximum value of indexed points as a function of step size. The optimum step size depends on the magnification and the board resolution/electronic step size. Grains/subgrains and texture, and grain boundary structure are readily obtained by EBSD. Strain......
of the electroactive species from bulk solution to the interface is the rate determining step, and the growth of nuclei is considered to be 3D taking into account of the overlap of diffusion zones. According...Electrocrystallization nucleation and growth of NiFe alloys on brass substrate ZHANG Zhao(张 昭) (Department of Chemistry, Zhejiang University, Hangzhou 310027, China) Abstract......
growth of intermetallic phase from separate sites, resulting in the formation of a continuous layer. The second step was the growth of the continuous intermetallic layer in the direction perpendicular..., Roudehen Branch, Islamic Azad University, P.O.

Modification of computer simulation of normal grain growth LI Jian(李 剑), LI Shi-chen(李世晨), ZHENG Zi-qiao(郑子樵), LIU Zu-yao(刘祖耀), CHEN Da-qin(陈大钦) (School of Materials Science and Engineering, Central South University, Changsha 410083, China) Abstract: A set of principles on transition probability was supplied for the physical process of grain growth. In accord with these principles......
of two reactions. For primary crystallization, the apparent activation energies, EIso and EKis and growth activation energies Eg are about 153, 166 and 288 kJ/mol, respectively. The interdiffusion of Al atoms is a rate-controlled step of formation of the α(Al) particles, but slow diffusion of Ni and Nd atoms plays a significant role in retarding growth of the a (Al) particles. For secondary......
