The two-body approximation of the excess entropy is used to study the interplay between the microstructural ordering and the entropy of undercooled liquid metals.
Such an effect is believed to be mainly associated with the formation of looser MAF and more RAF by the microstructural re-arrangement involving conformational ordering of partial amorphous chain segments and a significant interlamellae thickening.
Further, AgCl microstructures were found to have orderly self assembled on the DNA helices indicating the electrostatic interaction between Ag+ and phosphate side chain of DNA as a driving force for the formation of the material with ordered microstructural distribution of AgCl.
In fact, the orientations of mechanical e-twins are rotated more than 10° about the axis of kink bands, thus showing the validity of the inferred order of microstructural development.
Microstructural observations indicate an order of magnitude reduction in the prior β grain size, d, as well as a significant reduction in the α lath size, λ, with B additions.
Their immiscibility leads to interpenetrating structures, with typically smallest microstructural length scales on the order of several micrometres.
First, in order to study the microstructural properties of the weld, microstructure evolution of the weld zone is simulated with the cellular automaton (CA) method coupling the modified Laasraoui Jonas (LJ) model.
By considering the hardness and volume fraction of each microstructural feature, it is also found that the contributions of microstructural features to the integrated hardness increase in the order of αGB, αp, βGB, βbase.
The samples were characterized from a microstructural point of view, in order to evaluate the pore morphology, dimension and degree of interconnectivity.
It is shown that FOD-initiated cracks, that are of a size comparable with microstructural dimensions, can propagate at applied stress-intensity ranges on the order of ΔK∼1 MPa √m, i.e., a factor of roughly two less than the "worst-case" threshold stress-intensity range in Ti 6Al 4V for a crack of a size large compared to microstructural dimensions (a "continuum-sized" crack).
