Microstructure Formation with the Elastic Interactions of Internal Stress and Applied Stress
Microstructure formation under the applied strain for the alloys with different shear modulus and anisotropy were studied using the phase-field simulation. The uniaxial morphology depends on the magnitude of applied strain, the ratio of shear modulus and ratio of anisotropy between the precipitates and matrix. However, the morphology orientation depends not only on the sign and direction of applied strain, but also on the ratio of anisotropy and the ratio of shear modulus between the precipitates and matrix. The simulation results are helpful for the materials microstructure design and control by the combination of internal elastic stress and the applied strain.
