Microstructure-based Constitutive Models for Residual Mechanical Behavior of Aluminum Alloys after Fire Exposure
… considering solid solution, subgrain, and grain strengthening. A recovery model was used to predict subgrain growth and a recrystallization model was used to predict grain nucleation and growth, as well as subgrain annihilation. Strain hardening was predicted using the Kocks-Mecking-Estrin law …

Factors contributing to the yield strength of polycrystalline nickel-based superalloys
… applications, a full understanding of the strengthening mechanisms is required. If this were possible, alloy properties such as composition and microstructure could be optimized to the specific mechanisms known to be occurring. However, this is a complex task, as many underlying mechanisms …

Time-resolved and three-dimensional study of dislocation-particle interactions in aluminum and copper alloys
Dislocation-particle interactions in three alloys systems, Al-Cu, Al-Mg-Sc, and Cu-Co have been investigated using in situ straining experiments inside the transmission electron microscope, post mortem analysis, and electron tomographic reconstructions. Specifically, diffraction-contrast electron …

Novel integrated computational approach for designing Fe-Ni-based alloys
… parameters, such as the volume fraction and precipitate size after heat treatment (replicating the service conditions of automobile sealing parts) were thermokinetically calculated by adopting phase transformation software. The associated yield stress was then predicted using classical …
