How the tensile strength of a metal is increased by alloying?

Answer 1

Alloying metals make them stronger because in pure metals all the atoms are the same size and ordered but when another element is added then it makes the atoms irregular making the layers harder to shift, making it stronger.

An alloy is a mixture of two elements, one of which is a metal. Alloys often have properties that are different to the metals they contain. This makes them more useful than the pure metals alone. For example, alloys are often harder than the metal they contain.

Alloys contain atoms of different sizes, which distorts the regular arrangements of atoms. This makes it more difficult for the layers to slide over each other, so alloys are harder than the pure metal.

Answer 2

Converting pure metals into alloys usually increases the strength of metals. This is because when two pure metals are made into an alloy, a chemical reaction which is harder to break usually occurs.
