What Are Brittle and Ductile Meant?
Brittle and Ductile are the two important material properties (belongs to the strength of materials subject) that are used to describe the physical and chemical properties of materials. According to its properties, its application and usages will be vary. The term brittleness is the process of acquiring the brittle property by any material. Similarly, the ductileness is the term that can be used while mentioning the material property as ductile.
Brittle and Ductile Materials plays a major role in the mechanical field; both types will decide the application of the type of material at different areas.
What is Brittle Material?
Brittleness is one of the material properties where the breaking of the material will take place without any deformation even though the material is hard. The materials that possess the property of brittleness are called Brittle Materials.
Examples of Brittle Material:
Examples of brittle materials are as follows:
- Cast Iron,
- Concrete, etc.
What is Ductile Material?
Ductility is another type of material property where the deformation will take place with an external force before the material gets damaged. We can also say that the ductility is the property of the material where we can draw into the thin wires.
The materials that possess the property of ductility are called Ductile Materials.
Examples of Ductile Material:
Examples of ductile materials are as follows:
- lead, etc.
If we observe the Stress-Strain Diagram, the horizontal line (or x-axis) referring the Strain of the material and the vertical line (or y-axis) refers the Stress of the material. So, it is necessary properties (stress and strain) that need to be considered to evaluate the brittle and ductile materials.
Brittle materials can withstand heavy stress than ductile materials whereas; coming to the strain, the ductile materials can take and withstand even at high strain than brittle materials. This comparison is shown using a graph called the stress-strain diagram.
Difference between Brittle and Ductile Materials:
So, both brittle and ductile materials has opposite nature and properties. Let us learn the difference between brittle and ductile materials.
|Brittle Material||Ductile Material|
|While machining a brittle material, the chip formation is Non-Continuous; it means the breakage in the chip formation will take place.||While machining the ductile material, chip formation will be Continuous; it means the breakage in the chip formation will take place.|
|The brittle materials will break when we try to bend it||The ductile materials cannot break even they are bent.|
|Brittle materials have high Young’s Modulus.||Ductile materials have low Young’s modulus.|
|The breaks in brittle materials will be occurred without any sign of cracks or breaks.||We can observe the cracks in the ductile materials before it fails.|
|Brittle materials will get yield before Fracture Point.||Ductile materials will get deform before the Fracture point.|
Both brittle and ductile materials are opposite in properties but they are important in their field of applications because a few fields require the materials that possess high stress with low strain and a few fields require the materials that possess high strain with low stress. So, according to this, we can say that both are unique in their way and application.
