Difference between solidification of supermetals and metal alloy?

Answer 1

if we take example of binary alloy and binary intermetallic compound then in case of binary intermetallic compound the position of two types of atoms in a particular lattice structure remain fixed but in case of binary alloy the atoms position is not fixed although they formed the same lattice structure but the position of two types of atoms may not fixed in the lattice.

Answer 2

During solidification

1.pure metal converts from liquid state to solid sate at a single temperature while an alloy solidifies over a range of temperature.

2.pure metal composition remains constant throughout solidification process(its obvious) but the composition of alloy changes continuously. But the composition of alloy in the solid sate becomes same as that when it was in liquid state.that is, this change of composition take place only during liquid+ solid state.

importantly , all this occurs only during cooling under equilibrium conditions.

Answer 3

In a Substitutional Alloy, atoms of the solute take positions normally occupied by a solvent atom.

In a Interstitial Alloy, Solute atoms can occupy the "gaps" between the solvent atoms.interstitial alloy formed by wide range of metal with H,B,C,N etc

Answer 4

AlloysMixture or metallic solid solution composed of two or more metals, whose crystal structure differs from that of the other constituents. The term "alloy" is generally applied to any homogeneous molten mixture of two or more metals. Inter-metallic compoundAny of a class of substances composed of definite proportions of two or more elemental metals, rather than continuously variable proportions (as in solid solutions). Complex metallic alloys are intermtallic compounds with large unit cell.

The crystal structures and the properties of intermetallic compounds often differ markedly from those of their constituents. In addition to the normal valences of their components, the relative sizes of the atoms and the ratio of the total number of valence electrons to the total number of atoms have important effects on the composition of intermetallic compounds.

Answer 5

on solid solution the percentage of solids can be changed.....but on intermetallic compound the percentage must be fixed.....

subsitutional alloy

Answer 8

Alloys are mixtures of pure metals.
