On amorphization as a deformation mechanism under high stresses

Revealing the strengthening contribution of stacking faults, dislocations and grain boundaries in severely deformed LPBF AlSi10Mg alloy

“…9 b), are visible. What is also striking here is that the GPA shows large strain fluctuations around and within amorphous regions, suggesting that shear stresses may play a crucial role in the deformation-induced amorphization of the Si phase 26 , 27 . Such a large lattice distortion caused by chemical fluctuations can also act as a precipitate to pin the dislocations and produce dislocation loops, increasing the overall mechanical strength of material 28 .…”

Spiers Memorial Lecture: Mechanochemistry, tribochemistry, mechanical alloying – retrospect, achievements and challenges

“…Radicals, active states, metastable molecular forms, like zwitterions that are formed on mechanical treatment, can be long-lived, especially if stabilized at the interfaces in mechanocomposites. 78,82,90,163,164,176–185…”

On-Chip Very Low Strain Rate Rheology of Amorphous Olivine Films

“…Below this temperature, the presence of this amorphous intergranular film may impact the brittle-ductile transition in the lithospheric mantle. Understanding the mechanical properties of amorphous olivine (a-olivine) has therefore become a subject of great interest [3]. But this material is not easy to generate.…”
