Chemical etching was applied to reveal the crystal defects,such dislocations,Te inclusions and twins.

Lattice thermal conductivity is further decreased due to the extra electron-phonon scattering mode introduced by Te doping.

Effect of 80 t Converter-Ladle Argon Stirring-Concasting Steelmaking Process on Gas and Inclusion Content in Steel Q235A;

A primary investigation for the rapid determination of oxide inclusion in steel by differential heating method;

From the transversal section of columnar grains,it can be seen that impurities composed by oxide of Cr and Mn are observed in grain boundaries in this region.

Surface blisters of 2017 alloy annealed bars are formed in laminated surface including impurities.

Conformation,inclusions and organization of A36 layered cut-side sample have been ana-lyzed with XL-30 SEM and EDS, The results show that the crack of billet which create from inclusions, especially oxide and silicate, are mostly responsible for the layered cut-side sample.

The Eshelby's single inclusion theory has been extended to the theory of effective properties of composites with multi kind inclusions.

The article spreads Eshellby′s theory on a single inclusion to embedded in an infinite matrix the composite materials with arbitrary numbers of different inclusions.
