Data-driven body-centered cubic phase prediction in cobalt free high-entropy alloys
Xuliang Luo, Yulin Li, Tero Mäkinen +3
High-entropy alloys (HEAs) are known for superb combination of performance attributes, making them ideal for advanced applications, e.g., nuclear engineering. The concept of cobalt…
Stochastic ion emission perturbation mechanisms in atom probe tomography: Linking simulations to experiment
Aslam Shaikh, Tero Mäkinen, François Vurpillot +2
Field evaporation in atom probe tomography (APT) includes known processes related to surface migration of atoms, such as the so-called roll-up mechanism. They lead to trajectory ab…
Creep failure in heterogeneous materials from the barrier landscape
Juan Carlos Verano-Espitia, Tero Mäkinen, Mikko J. Alava +1
Stressed under a constant load, materials creep with a final acceleration of deformation and for any given applied stress and material, the creep failure time can strongly vary. We…
Growth and prediction of plastic strain in metallic glasses
Tero Mäkinen, Anshul D. S. Parmar, Silvia Bonfanti +1
Predicting the failure and plasticity of solids remains a longstanding challenge, with broad implications for materials design and functional reliability. Disordered solids like me…
Effect of quenched heterogeneity on creep lifetimes of disordered materials
Juan Carlos Verano-Espitia, Jérôme Weiss, David Amitrano +2
We revisit the problem of describing creep in heterogeneous materials by an effective temperature by considering more realistic (and complex) non-mean-field elastic redistribution…
Crack propagation by activated avalanches during creep and fatigue from elastic interface theory
Tero Mäkinen, Lumi Tuokkola, Joonas Lahikainen +3
The growth of cracks combines materials science, fracture mechanics, and statistical physics. The importance of fluctuations in the crack velocity is fundamental since it signals t…
