Apure metal can be strengthening by addition of impurities. identify strengthening mechanism that utilize impurities and discuss the method of strengthening

Explanation:

Strengthening is the method to improve the strength of material because different type of material property requires for different requirement .Some times requires more ductility,some time requires more strength.

When impurities are mixed with the pure metal then the strength of metal will increases and this is called the strengthening of metal.

The methods of strengthening are as follows

1.Solid solution strengthening and alloying

2.Work hardening

3.Transformation hardening

4.Grain boundary  strengthening

5.Precipitation hardening

the equation above shows how temperature f, measured in degrees fahrenheit, relates to a temperature c, measured in degrees celsius. based on the equation, which of the following must be true?

a temperature increase of 1 degree fahrenheit is equivalent to a temperature increase of

5

9

degree celsius.

a temperature increase of 1 degree celsius is equivalent to a temperature increase of 1.8 degrees fahrenheit.

a temperature increase of

5

9

degree fahrenheit is equivalent to a temperature increase of 1 degree celsius.

a) i only

b) ii only

c) iii only

d) i and ii only
