Record 1 2012-01-16

English

Subject field(s)
  • Analytical Chemistry
  • Thermodynamics
DEF

An empirically derived graph showing the limiting conditions for solid, liquid, and gaseous phases (states) of a single substance or of a mixture of substances while undergoing changes in pressure and temperature or in some other combination of variables, such as solubility and temperature.

CONT

Phase diagrams are widely used in studies of mineral equilibria in connection with the conditions of formation of rocks and minerals within the Earth. They also are invaluable when designing industrial equipment and seeking optimum conditions for manufacturing processes, and in determining the purity of substances.

French

Domaine(s)
  • Chimie analytique
  • Thermodynamique
DEF

Graphique permettant de déterminer les espèces ou les phases prépondérantes d'un système chimique dans des conditions thermodynamiques données.

CONT

Pour toute valeur des paramètres thermodynamiques définissant l'état d'un système, on peut déterminer la phase stable de ce dernier. Les diagrammes de phases, très utilisés en métallurgie, représentent graphiquement les domaines d'équilibre de ces différentes phases.

Spanish

Campo(s) temático(s)
  • Química analítica
  • Termodinámica
DEF

Diagrama de variables intensivas de los sistemas polifásicos en equilibrio, que permite cuantificar las variaciones que se producen en las fases cuando son modificadas.

English

Subject field(s)
  • Mechanical Transmission Systems
DEF

Graphical representation of the sequence of operations and control signals of a fluid power circuit, generally for a complete cycle.

French

Domaine(s)
  • Transmissions mécaniques
DEF

Représentation graphique de la séquence des opérations et des ordres de commande d'un circuit hydraulique ou pneumatique, généralement pour un cycle complet.

Spanish

Record 3 1997-05-08

English

Subject field(s)
  • Metallurgy - General
DEF

A graphical representation of the temperature and composition limits of phase fields in an alloy or ceramic system as they actually exist under the specific conditions of heating or cooling.

OBS

A phase diagram may be an equilibrium diagram, an approximation to an equilibrium diagram, or a representation of metastable conditions or phases.

French

Domaine(s)
  • Métallurgie générale
DEF

Représentation graphique des domaines de stabilité en température, pression et composition des phases d'un alliage à l'état d'équilibre. Dans les systèmes métalliques, la pression est en général considérée comme constante et égale à la pression atmosphérique.

Spanish

  • Radar, Radio Guidance and Goniometry
DEF

The spatial distribution of the relative phase of a field vector excited by an antenna.

French

Domaine(s)
  • Radar, radioguidage et radiogoniométrie
