    evaluation of composition-dependent dislocation mobility in MAX Phases'

## Description

- description: MAX phases serve as an ideal model system for studying the crossover
    between metallic and ceramic behavior, and improved ceramic ductility. This ductility
    is primarily linked to the anomalously easy glide of basal plane dislocations;
    yet a full theoretical understanding of the characteristics governing their mobility
    remains a subject of continuing research. Following recent efforts using atomistic
    simulations of MAX phase basal plane dislocation cores, the present study focused
    on an experimental evaluation of friction and Peierls stresses in three representative
    MAX phase compounds, Ti3AlC2, Ti3SiC2, and Cr2AlC, using micropillar compression
    at cryogenic temperatures. The study examines specifically the effects of temperature,
    size, and pristine dislocation morphology under aid of crystal plasticity finite
    element simulations to derive the lattice resistance for each compound and compare
    it with previously simulated results. The results confirm a significant role of
    core structures and bonding characteristics on MAX phase dislocation plasticity,
    and further indicate a non-negligible influence of dislocation interactions or
    forest hardening on bulk MAX phase ductility. The cryogenic tests presented here
    mark the first such experiments in MAX phases and open new pathways for understanding
    their deformation behavior at low temperatures.
