• Помогите ответить на вопросы из текста: Вот текст: Metals ...

    Irregular crystals are called grains. The properties of the metals depend on the size, shape, orientation, and composition of these grains. In general, a metal with small grains will be harder and stronger than one with coarse grains.

    Heat treatment such as quenching, tempering, or annealing controls the nature of the grains and their size in the metal. Small .

  • Ionic Coordination and Pauling's Rules

    If all of the atoms in a crystal are the same size, then there are two ways to pack the atoms to form a crystal structure. In this case, the maximum number of atoms that be coordinated around any individual is 12. We call this 12fold coordination. There are two ways that atoms can be packed in 12fold coordination. First, examine a single layer of atoms of equal size. Note that .

  • Grain Size : What is Grain Size? How is Grain Size ...

     · Many crystals can be composed of a single grain. Granular material can vary from very small colloidal particles to boulders, through clay, silt, sand, gravel, and cobbles. The size of a compact, threedimensional object such as a sedimentary grain might be indexed by some measure of its volume, or by some linear measure of its geometry. For geometrically regular objects, either carries ...
