Record 1 2006-07-06

English

Subject field(s)
  • Strength of Materials
  • Qualities of Aluminum and Aluminum Alloys
CONT

Grain refinement improved the hot-tearing resistance of the aluminum alloy.

French

Domaine(s)
  • Résistance des matériaux

Record 2 2006-07-06

English

Subject field(s)
  • Refining of Metals
CONT

Grain refinement refers to the use of an additive to reduce the final grain size during solidification.

OBS

CANMET-MTL researchers learned that hexachloroethane increased the strength of AZ91 magnesium alloy by approximately 12% and the ductility by 25% through grain refinement. More importantly, it reduced the tendency of castings to hottear while cooling in the mould.

French

Domaine(s)
  • Affinage des métaux
CONT

On entend par affinage du grain l'utilisation d'un additif pour réduire la taille finale du grain durant la solidification.

OBS

Des chercheurs du LTM-CANMET ont réalisé que l'hexachloroéthane accroît la résistance mécanique de l'alliage de magnésium AZ91 d'environ 12 %, et sa ductilité de 25 %, par l'affinage du grain. De plus, il diminue les criques de solidification dans les pièces coulées durant leur refroidissement dans les moules.

Record 3 1999-10-12

English

Subject field(s)
  • Foundry Practice
DEF

A substance which augments a melt, usually in the latter part of the melting operation, thus altering the solidification structure of the cost metal, as in grain refinement of aluminium alloys.

Key term(s)
  • inoculating agent

French

Domaine(s)
  • Fonderie
DEF

Substance que l'on ajoute dans un métal ou un alliage fondu pour favoriser la germination, donc accélérer la solidification. (Dans la fonte liquide, on introduit des inoculants pour créer des germes de graphite.)
