기공이 있는 나노결정재료의 탄성계수에 대한 상혼합모델 = Mechanical Behavior:A Phase Mixture Model on the Elasticity of Nanocrystalline Materials with Pores

다국어 초록 (Multilingual Abstract)

A phase mixture model was considered in which nanocrystalline materials are treated as a mixture of crystalline phase, intercrystalline phases (grain boundary, triple line junction and quadruple node) and pores. In order to investigate the effects of grain size and porosity on the elastic modulus, Budiansky's self-consistent method in conjunction with the phase mixture model was employed. The calculated results are compared with the experimental measurements in the literature. The elastic modulus of nanocrystalline materials decreases with a decrease of the grain size and the decrement is relatively large at grain sizes below about 10 ㎚. The effect of porosity, however, is substantially greater than the grain size effect.
