Строение обозначает способ расположения атомов металла относительно геометрической формы в твердых кристаллах, а также регулярное или упорядоченное расположение различных видов атомов металла и их отношение друг к другу в таком кристалле.
The word constitution used with reference to metallic sub¬stances does not have the same meaning as composition. Constitution denotes the manner of arrangement of the metal atoms as to geometric form in solid crystals, and the regular or or¬dered arrangement of different kinds of metal atoms and their relation to each other in such a crystal.

Плотно упакованный кубический материал: медь, никель, свинец, алюминий, кобальт, серебро, золото, платина.
Hexagonal close-packed: zink, cadmium, magnesium, beryllium, titanium.
Close-packed cubic: copper, nickel, lead, aluminium, cobalt, silver, gold, platinum.
Образование кристаллов металла в расплаве начинается на каждой охлаждающей поверхности жидкой массы и распространяется от внешней поверхности к внутренней по мере потери тепла из массы.
The formation of metal crystals within a melt begins at each cooling surface of the liquid mass and extends from the exterior to the interior as heat is lost from the mass.
Constitution denotes the manner of arrangement of the metal atoms as to geometric form in solid crystals, and the regular or ordered arrangement of different kinds of metal atoms and their relation to each other in such a crystal.
Точки плавления и кипения. Температура, при которой плавится металл, называется точкой плавления, металлы с более низкой температурой плавления обычно являются мягкими металлами, а металлы с высокой температурой плавления - твердыми металлами.
Melting and Boiling Points. - The temperature at which a metal melts, is called the melting point, the metals of lower melting points are generally the soft metals and those of high melting the hard metals.
The boiling point of a substance depends on the surrounding-pressure. The term "boiling point" refers to the temperature at which the metal boils under normal atmospheric pressure.
Электрическая Проводимость. Электропроводность вещества - это электропроводящая способность единицы длины на единицу площади поперечного сечения.
Electrical Conductivity. - The electrical conductivity of a substance is the electrical conducting power of a unit length per unit of cross-sectional area.
The electrical resistance of metals or alloys is increased by decreasing the size of the crystals and, therefore, increasing the number of crystal boundaries.
Теплопроводность измеряется как теплопроводящая способность единицы длины или толщины вещества на единицу площади поперечного сечения.
Heat conductivity is measured as the heat conducting ability of a unit length or thickness of a sub¬stance per unit of cross-sectional area.
the heat conducting ability of a unit length or thickness of a substance per unit of cross-sectional area.
Магнетизм измеряется как магнитная сила, действующая на единицу объема вещества при стандартной силе намагничивания.
Strong permanent magnets have been made chiefly of one of several compositions of steel, but in recent years a number of magnet alloys of much greater magnetism, ...
Magnetism is measured as the magnetic for¬ce exerted by a unit volume of a substance under standard ma¬gnetizing force.
Пористость, качество, содержащее поры, - это отсутствие плотности. Плотность, с другой стороны, обозначает вес на единицу объема.
Porosity, the quality of containing pores is lack of denseness. Density, on the other hand, denotes weight per unit of volume.
The distinction will be manifest from the fact that some heavy metals, like grey cast ironware porous enough to leak under heavy hydraulic pressures, whereas some lightweight metals, like aluminium, are dense and compact.
Большинство металлов серебристо-белого или серого цвета. Медь - единственный красный металл, а золото - единственный желтый, хотя ряд сплавов на основе меди также желтого цвета.
Most of the metals are silvery white or grey in colour. Copper is the only red metal, and gold the only yellow one, although a number of copper-base alloys are also yellow.
The distinction will be manifest from the fact that some heavy metals, like grey cast ironware porous enough to leak under heavy hydraulic pressures,
Все твердые металлы имеют металлический блеск, хотя истинный цвет и блеск многих металлов часто затемняются оксидным покрытием, которое может быть белым, серым, красным, коричневым, голубоватым или черным.
All solid metals have metallic lustre, although the true colour and lustre of many metals are often obscured by a coating of oxide — which may be white, grey, red, brown, bluish, or black.
Strong permanent magnets have been made chiefly of one of several compositions of steel, but in recent years a number of magnet alloys of much greater magnetism, able to exert forces many times their own weights, have been developed.
