What is an alloy explain the objective of their formation?
Plz guys help me fast tomorrow is my exam...
Answers
Alloy isa substance which isamade up of a pure altra carbon
Answer:
Alloy, metallic substance composed of two or more elements, as either a compound or a solution. The components of alloys are ordinarily themselves metals, though carbon, a nonmetal, is an essential constituent of steel.
Almost all metals are used as alloys—that is, mixtures of several elements—because these have properties superior to pure metals. Alloys are usually produced by melting the mixture of ingredients.
Objectives of Alloy formation:
Enhance the hardness of a metal: An alloy is harder than its components. Pure metals are generally soft. The hardness of a metal can be enhanced by alloying it with another metal or nonmetal.
Lower the melting point: Pure metals have a high melting point. The melting point lowers when pure metals are alloyed with other metals or nonmetals. This makes the metals easily fusible. This property is utilized to make useful alloys called solders.
Enhance tensile strength: Alloy formation increases the tensile strength of the parent metal.
