Propagating bands of plastic deformation in a metal alloy as critical avalanches
Tero Mäkinen, Pasi Karppinen, Markus Ovaska +2
The plastic deformation of metal alloys localizes in the Portevin--Le Chatelier effect in bands of different types, including propagating, or type 'A' bands, usually characterised…
Probing the transition from dislocation jamming to pinning by machine learning
Henri Salmenjoki, Lasse Laurson, Mikko J. Alava
Collective motion of dislocations is governed by the obstacles they encounter. In pure crystals, dislocations form complex structures as they become jammed by their anisotropic she…
Plastic yielding and deformation bursts in the presence of disorder from coherent precipitates
Henri Salmenjoki, Arttu Lehtinen, Lasse Laurson +1
Alloying metals with other elements is often done to improve the material strength or hardness. A key microscopic mechanism is precipitation hardening, where precipitates impede di…
Machine learning depinning of dislocation pileups
Mika Sarvilahti, Audun Skaugen, Lasse Laurson
We study a one-dimensional model of a dislocation pileup driven by an external stress and interacting with random quenched disorder, focusing on predictability of the plastic defor…
