What are the strengthening mechanisms commonly used in engineering materials? Describe in detail and explain each mechanism thoroughly

Solution

the strengthening mechanisms commonly used in engineering materials are:

-metal strengthening mechanisms:

1)work hardning: it is also known as strain hardning or cold working. it occurs due to dislocation movements within the crystal structure of the material

2) solid solution strengtening: it is a type of alloying, it is a technique in which by adding atoms of one element to the crystalline lattice of another element.

3)Precipitation hardening: it is also known as age hardening. it is a heat treatment used to increase the yield strength of different materials.

4)Grain boundary strengthening: it is a method of strengthening materials by changing grain size influence dislocation movement and yield strength.

5)Transformation hardening: it is a ahrdening process often used in addition to carburising or nitriding, and is primarily used to improve the mechanical properties of the surfaces of steel components.
