To strengthen metal materials, grain refinement by severe plastic deformation is often used [4].
Si and Mg2Si precipitated in the grain boundary of these two materials.
Fig. 3 shows the area fraction of the precipitation and room-temperature tensile properties of the three materials.
Fig. 4 shows the stress–strain curves of the artificially aged, forged, and forged–rolled materials.
SEM images of the forged and forged–rolled materials are shown in Fig. 5.

A meso-damage model is proposed, which include the damage law under complex stress state for brittle materials, and the damage evolution based on stiffness degradation.
With the same idea, Chen Y Q(2002) simulated the fracture course of 3-D sample of brittle materials.
For the brittle materials of rock like, the damage mechanism of tension strain is appropriate, namely the meso-MSS is tensile fractured.

Introduction Nanometer materials possess fancifully physical and chemical properties different form bulk materials due to the quantum size effect resulted from the small particle diameter together with large surface area [1].
Nanometer materials have been attracted much attention since they exhibit the excellent performance in the electricity, magnetics and photocatalytic area.
It is well known, CdS is an important nanometer semiconductor materials with band gap of 2.42 eV.

So it can be concluded that the parent materials of the sediment control Cr and PC3 presents the lithogenic sources.
Cluster III (Cr) reveals that Cr is not greatly related to other elements and mainly derives from the soil parent materials.
According to PCA, CA, and HCA results, two main sources can be distinguished: (1) Cu, Pb, Zn and As mainly originate from human activities; (2) Cr is separated from the other elements and mainly derives from the soil parent materials.

As traditional vibration isolation systems cannot satisfy these demands, engineers are giving more attention to so-called smart materials.
Smart materials sense changes in their environment and actively alter some physical or chemical property in response to the change [2].
Examples of such materials are magnetorheological elastomers (MRE).
