An in situ study of twinning at crack tip in a TiAl-base alloy has been performed.The result shows that twinning with long shear vector(2/6) [112] can generate on(111) plane, even though usually it is very difficult to occur because of the high energy barrier. It was further shown that (1/6) [112](111) twinning is considerably easier to generate. Furthermore,(1/2)<110) ordinary dislocations were very active and dominated nearly the whole plastic zone, in spite of low Schmid factors. On the other hand, however <101) and (1/2) <112] superdislocations with higher Schmid factors can hardly be observed.

Introduction to atmospheric corrosion research in China

Science and Technology of Advanced Materials

In this paper, we introduce the research on atmospheric corrosion in China. We describe the climate characteristics and the classification of atmospheric corrosivity across the whole country. We also describe the rusting evolution under simulated wet/dry cyclic conditions. (C) 2007 NIMS and Elsevier Ltd. All rights reserved.

STRUCTURE AND MAGNETIC-PROPERTIES OF CEFE13-XSIX COMPOUNDS

Journal of Applied Physics

New iron-based rare-earth CeFe13-xSix (2.4 less than or equal to x less than or equal to 2.6) intermetallic compounds which crystallized in the NaZn13-type structure with Fm3c(O-h(6)) space-group symmetry have been found. The ac susceptibility and the magnetization curve measurements are reported. The substitution of silicon for iron leads to an increase of the Curie temperature and a reduction of the unit-cell volume. The saturation magnetic moment decreases from 15.7 mu(beta)/f.u. to 13.4 mu(beta)/f.u. with x=2.4-2.6. (C) 1995 American Institute of Physics.
