THERMAL SHOCK [3 records]

Record 1 2005-08-17

English

Subject field(s)
  • Thermodynamics
  • Strength of Materials
DEF

The shock experienced by a material when it is subjected to sudden changes in temperature.

CONT

Possible accelerated casing corrosion, due to contact with cold oxygenated water from the quenching operation or mechanical failure caused by thermal shock is no longer a constraint on a casing monitoring programme.

French

Domaine(s)
  • Thermodynamique
  • Résistance des matériaux
DEF

Phénomène qui affecte les matériaux lorsqu'ils reçoivent une grande quantité d'énergie en un temps très court.

OBS

De tels chocs se produisent sur certaines pièces, au contact de fluides chauds (alliages ou briques réfractaires), pendant le travail à chaud des métaux (étampes de forge, cylindres de laminoir), ou à la surface des engins spatiaux à leur rentrée dans l'atmosphère. Ils peuvent provoquer des criques ou un écaillage.

Record 2 2003-09-17

English

Subject field(s)
  • Genetics
CONT

The term 'cold shock' has been used to describe this sensitivity to a reduction in temperature. It is independent of, or can occur in the absence of, freezing. ... Cold shock is often related to the rate of cooling, rapid cooling usually being more damaging than slow cooling. It may, as for erythrocytes, be mediated by exposure to high concentrations of sodium chloride ... This injury can also be reduced or avoided by incorporating cryoprotectants, specific phospholipids ... or various other compounds ...

French

Domaine(s)
  • Génétique
CONT
