Question

how are allogs prepared? is it homogenes and heterogeneous mixture give justification
​

Answer 1

Answer:

The majority of alloys are prepared by mixing metals in the molten state; then the mixture is poured into metal or sand moulds and allowed to solidify. Generally the major ingredient is melted first; then the others are added to it and should completely dissolve.

We also know that in homogeneous mixtures, the composition of the materials are fixed i.e. they are in fixed proportion and in heterogeneous mixtures, the proportion is not fixed. Also, in Alloys proportion of metals is fixed. So, Alloy is a homogeneous mixture.

Answer 2

Answer:

The majority of alloys are prepared by mixing metals in the molten state; then the mixture is poured into metal or sand moulds and allowed to solidify. Generally the major ingredient is melted first; then the others are added to it and should completely dissolve.

An alloy is a material composed of two or more metals or a metal and non metal. It may be a solid solution of the elements of single phase or a mixture of two or more metallic phases. Solid alloys give a single solid phase microstructure. Alloys are used where their properties are superior to those of pure component elements. Examples are steel,solder,brass,amalgam etc.
