and KOC [12] studied the grain size effect in hydraulic bulge test. They concluded that the interaction and interplay among grain size, feature size and specimen size affect the material deformation...): 132-136. [12] MAHABUNPHACHAI S, KOC M.

], which are Yangjiang B sag, Yangjiang horst, Yangjiang A sag, Yangjiang low bulge, Qionghai sag, Qionghai low bulge, Wenchang A sag, Wenchang B sag, and Wenchang C sag. The study area is located......
is similar to that of Composite A. However, the reduction of COF is larger, from 1.06 to 0.76. There is not a sharp increase of initial COF which results from the hard ceramic bulge on friction......
. This indicates that very small applied field only causes the domain wall to bulge in the direction of applied magnetic field and the domain walls remains to be pinned at the original sites. There is a so-called......
in Fig.5, together with a complex inner surface, the metal flow velocity to the upper end face varies so much that a bulge is formed which might result in fold or under filling. Fig.6 indicates the under......

. The formation of large amount of Y2O3 particles inside the Ag-Y alloy particles gives rise to the partial stress concentration, which results in the bulge part on the surface of alloy particles......
