Solid faceted crystals are those in which the original crystal form is often no longer discernible and the crystals begin to take on an angular, faceted or striated appearance with straight edges and angular corners beginning to predominate. Faceted grains typically tend to be larger grains and are often significantly larger than the grain from which they formed... Commonly referred to as "facets" or "sugar snow" these grains tend to be found in softer or weaker snowpack layers. Faceted grains typically form when there is a strong temperature gradient in the snowpack(>1 degree/10 cm). This strong temperature gradient occurs most often in areas where the snowpack is shallow and temperatures are cold. 8, record 1, English, - facet

There is a weak layer of facets buried deep in the snowpack. [Example approved by the Avalanche Bulletin Terminology Standardization Committee.] 2, record 1, English, - facet
Record number: 1, Textual support number: 1 OBS
When faceted crystals develop deep in the snowpack, they are usually referred to as "depth hoar" crystals. Because these angular, faceted crystals have relatively no internal cohesion or bonding, they behave much like sugar crystals and are frequently referred to as "sugar snow." 9, record 1, English, - facet

Record number: 1, Textual support number: 1 CONT
[...] l'effet de courbure permet au début de la métamorphose [de moyen gradient] de provoquer la sublimation des petits grains, induisant une augmentation moyenne des tailles de grains. Le résultat global est donc l'apparition d'un type de grains anguleux comportant des facettes faisant des angles à 120° [...]. Ces grains sont appelés grains à faces planes. 4, record 1, French, - grain%20%C3%A0%20faces%20planes

Les métamorphoses de la neige sèche. [...] Le devenir des particules reconnaissables va dépendre de la valeur du gradient de température de la couche concernée : - par faible gradient, elles vont se transformer en grains fins; - par moyen gradient, elles vont se transformer en grains à faces planes; - par fort gradient, elles se transformeront en grains à faces planes (passage intermédiaire obligé) puis en gobelets. Ces transformations sont irréversibles : il n'y a pas de retour en arrière possible. 5, record 1, French, - grain%20%C3%A0%20faces%20planes

Equal-channel angular processing(ECAP) is an efficient method of refining grain size via severe plastic deformation. The ECAP technique retains the size and shape of the billet, induces large cumulative strains in the material, and develops different microstructures.... Segal and collaborators first developed the ECAP technique to process materials by severe plastic deformation. 1, record 2, English, - equal%2Dchannel%20angular%20processing

Procédé développé par Segal en 1974 qui permet d'obtenir d'importantes déformations plastiques. Cette technique met en évidence le durcissement du matériau jusqu'à sa limite théorique et le développement d'une microstructure très fine (formée de nanomatériaux). 1, record 2, French, - extrusion%20angulaire%20%C3%A0%20section%20constante
