Electrocrystallization nucleation and growth of NiFe alloys on brass substrate ZHANG Zhao(张 昭) (Department of Chemistry, Zhejiang University, Hangzhou 310027, China) Abstract: The electrocrystalliztion nucleation and growth process of Ni-Fe alloy was studied using cyclic voltammetry and chronoamperometry. The results show that, in the case of high deposition overpotential......
between the primary dendrite arm spacing parameters (λmax, λave, λmin) of Al-7Si-0.36Mg alloy and growth velocity were expressed, and λmax/λmin≈3. The simulated results show a quite good agreement..., such as growth velocity v, temperature gradient G, interfacial energy effect, solute diffusion coefficient DL, as well as the deviation angle θ between the dendrite growth direction, and heat flux......
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......
