The interface behavior sample of Al2O3 mould shell single crystal alloy(DD3,DD6) in investment casting was prepared by direct pouring.

The studies on aluminum borate whisker-reinforced magnesium matrix composites,especially on their fabrication methods,properties,interface behaviors and effect of fabrication methods are reviewed.

In this paper,the interface behavior of Precipitated Calcium Carbonate(PCC),which was treated by cationic surface modification agent was studied.

By defining the product of the tensile stress and the time as a parameter called tensile impulse (I), the statistic results indicate that an obvious critical behavior for the damage evolution appears with the increasing of I.

The critical behavior of nonlinear properties in the component composites is studied.

After correlatively analysing the fragments, the signal of critical behavior has been found and critical exponents were also extracted.

Based on the fabric pullout test and the analysis of the SEM images of the appearance of fibers which remained in the glass fabric reinforced cement after pullout test,the influence of the silane coupling agent or wax treatment on the interfacial behavior of glass fabric reinforced cement composites was studied.

Two series of curves, such as maximum pull - out force versus embedded length and pull - out force versus fiber displacement, are got and the interfacial behaviors are also discussed.
