French term
rupture à excroissance
French to English
Tech/Engineering
Manufacturing
I'm looking for help with two separate, but linked, terms relating to quasi-cleavage fractures affecting metal:
une rupture de quasi-clivage peut associer une rupture de coupure (cassante) et une rupture à excroissance (ductile), un type de rupture intermédiaire.
une rupture de quasi-clivage peut associer une rupture de coupure (cassante) et une rupture à excroissance (ductile), un type de rupture intermédiaire.

Selected
ductile fracture
As for the sister question, I don't know where they get 'excroissance', but 'ductile' is in the question.

Aha! It appears 'excroissance' is 'tear ridge' in English, so maybe you can work that into the translation
"Les ligaments [this IS about steel] rompus par déchirure ductile et réunissant les facettes du clivage forment des excroissances qui sont appelées dans la littérature anglo-américaine "tear ridges". Aux faibles grossissements ces formations permettent de déterminer la position où le clivage a été amorcé, car l'ensemble de ces lignes converge vers le site d'amorçage. Au niveau local la situation est beaucoup plus complexe. Les rivières caractéristiques du clivage, qui suivent la direction de la propagation de la fissure principale, sont très influencées par la microstructure."

Earlier I came across 'ductile tears' [that's neither ducks nor crocodiles].

So 'fracture with tear ridges (ductile)', 'ductile fracture with tear ridges', 'fracture with ductile tearing', etc.

* "Fracture toughness testing in the transition region often causes DUCTILE TEARING to precede cleavage fracture. The effect of ductile tearing on the fracture probability has in recent years become a subject of great interest."
* "Over the mid-to-upper region of the ductile-to-brittle transition region, TRANSGRANULAR CLEAVAGE AND DUCTILE TEARING define two competing failure mechanisms in ferritic steel. At metallurgical scales (≲50 μm), formation and growth of the voids driving ductile crack extension likely alter the local stress fields acting on the smaller inclusions that trigger cleavage fracture. "
* "The fracture resistance of ferritic steels in the ductile/brittle transition regime is controlled by the COMPETITION BETWEEN DUCTILE TEARING AND CLEAVAGE FRACTURE. Under typical conditions, a crack initiates and grows by DUCTILE TEARING but, ultimately, failure occurs by catastrophic cleavage fracture. "

: "ductile tearing" makes more sense - metal being stretched before snapping (="ductile") as opposed to a sharp/clean break for "brittle fracture".// 'excroissance' is 'tear ridge' - exactly!

: Probably just "extrusion fracture".

: there is nothing to suggest that this "rupture à excroissance (ductile)" was caused during a fabrication process that included extrusion, on the contrary that's the LEAST likely explanation in this ST.

Discussion
What is the whole text about?
When and where is this metal failing? During the fabrication process?
Or is it about mechanical failure of finished metal parts, during the life cycle of the assembled product?
That little detail makes a HUGE difference ...
What is the most likely:
in this ST "l'excroissance" is the metal that was pulled out of the mass by stretching while the metal was being pulled apart before snapping - NOT metal that was pushed out by some extrusion process.
A part made of brittle metal when overloaded will break like glass or ceramic - a clean break without any lasting deformation (the broken bits fit exactly); a part made of ductile material will stretch before breaking, the permanently stretched edges of the rupture are "l'excroissance" this ST is about.
Fairly sure of that, but context needed for confirmation.
