Transient Stresses in Bimodal Compacts During Sintering
A method is described and used to evaluate the transient stresses in a sintering compact of ZnO containing a hard, dense dispersion of SiC. A hard second phase can severely limit densification rates by generating a mean hydrostatic stress, σh, which opposes the compressive sintering stress of the matrix. σh rapidly increases with increasing volume fraction, ƒ, of the second phase. The interface stress, σi., at the boundary increases with decreasing ƒ, σi can attain large values, especially in the intermediate stage of sintering. The effect of these stresses on microstructural development is considered.
