Effects of aging on precipitation and shape memory of Fe–Mn–Si–Cr–Ni based alloy with V and N addition

Autor: Liming Yu, K. Li, Zhi Zhong Dong, Z. Liu, Qing-Xiang Guo

Publikováno v: Materials Science and Technology. 30:1477-1480

The effects of aging on the precipitation of the second phase and the shape memory effect (SME) of an Fe–Mn–Si–Cr–Ni based alloy containing V and N elements (0·9 wt-%) have been investigated. The results showed that VN particles, precipitate

Inﬂuence of VC Precipitation on the Shape-Memory Effect and Corrosion Resistance on an Fe–Mn–Si–Cr–Ni Alloy

Autor: Zhi Zhong Dong, Ya Peng Wang, Kang Li, Hua Jiang, Lin Zhang, Yong Chang Liu, Zhi Chao Liu

Publikováno v: Advanced Materials Research. :134-137

The shape-memory effect (SME) and corrosion resistance of an Fe-20Mn-5Si-10Cr-5Ni- 0.7V-0.2C alloy, before and after aging, were investigated. The results showed that VC precipitation and bending temperatures obviously affect the alloy’s SME. Nearl

Effect of Sn-doping on the sintering process of MgB2 and its superconductive properties

Autor: Hua Jiang, Y.C. Liu, Zhi Zhong Dong, J. Huo

Publikováno v: Journal of Materials Science: Materials in Electronics. 22:233-237

Bulk (Mg1.02B2)1−xSnx samples (x = 0.0, 0.01, 0.03 and 0.05) were synthesized by in situ sintering at 850 °C for one hour. Based on the phase identification and microstructure observation, the Mg2Sn and Sn impurities are found as the main impuriti
