作者： Chun-Ming Liu ph.d. Editor-in-Chief

From Executive Editor to Editor-in-Chief is a big jump for me, and means many more responsibilities. I could feel the pressure on my shoulders; from the hopes of my predecessors, my colleagues, and the board members. As a journal with a 57-year history, JIpB has built its credit over the years, publishing many original works in both Chinese and English. however, in the international scientific community, JIpB is still a minor player, especially under the current not-so-healthy impact factor-driven publishing environment.

Electroless Ni-Fe-p alloys in an alkaline bath were plated. The effects of deposition parameters on the plating rate and the coating composition were examined. The weight loss test and the anodic polarization measurement of the deposits in 3.5 wt pct NaCI solution (ph7.0) showed that the deposits with the mole ratio of NiS04/FeSO4 being 0.07:0.03, ph8.0 and 7.5 possess better corrosion resistance than that of the other deposits and the Ni-Fe-p deposits did not form passive films in this environment. In 5.0 wt pct NaOh solution, the Ni-Fe-p deposits have better corrosion resistance and formed passive films.

Journal of Materials Science & Technology 2005年第1期21卷 5-9页

作者： Guozheng KANG, Qianhua KAN and Juan ZhANGdepartment of Applied Mechanics and Engineering, Southwest Jiaotong University, Chengdu 610031, Chinaprof., ph.d., dept. of Appl. Mech. and Eng. Southwest Jiaotong Univ. Chengdu 610031 China

The strain cyclic characteristics and ratcheting behavior of 25CdV4.11 steel were studied by the experiments under uniaxial cyclic loading with relatively high cyclic number and at room temperature. The cyclic hardening/softening feature of the material was first observed under the uniaxial strain cycling with various strain amplitudes. Then, the ratcheting behavior of the material was researched in detail, and the effects of stress amplitude and mean stress on the ratcheting were discussed under uniaxial asymmetrical stress cycling. Comparing with the experimental results of SS316L stainless steel, it is concluded that the material exhibits remarkable cyclic softening feature, and then a special ratcheting behavior is caused. Some conclusions useful to establish corresponding constitutive model are obtained.
