What is strain hardening process What are the practical outcomes of it?

Strain hardening is an increase in the strength and hardness of the metal due to a mechanical deformation in the microstructure of the metal. When a material is plastically deformed there is no longer a linear relationship between the stress and strain as there is for elastic deformation.

Why strain hardening is done?

Strain hardening (also called cold working) is an important strengthening process for aerospace alloys that involves plastically deforming the material during manufacturing to greatly increase the number of dislocations.

What is strain process?

straining, in cooking, the separation of liquid from solids using a strainer or sieve. straining (puréeing), the process of making a mash or purée by forcing through a sieve, rather than using a power blender.

What is strain hardening region?

One of stages in the stress-strain curve is the strain hardening region. This region starts as the strain goes beyond yield point, and ends at the ultimate strength point. It is called cold-working because the plastic deformation must occurs at a temperature low enough that atoms cannot rearrange themselves.

What is sprain and strains?

The difference between a sprain and a strain is that a sprain injures the bands of tissue that connect two bones together, while a strain involves an injury to a muscle or to the band of tissue that attaches a muscle to a bone.

What causes sprains and strains?

Most sports injuries, such as sprains or strains, are caused by minor trauma. Sprains are ligament injuries resulting from wrenching or twisting a joint. Strains are injuries to a muscle or tendon, and are often caused by overuse, force, or stretching.

What is the result of a strain?

Strains can be acute or chronic. An acute strain is caused by trauma or an injury such as a blow to the body; it can also be caused by improperly lifting heavy objects or over-stressing the muscles. Chronic strains are usually the result of overuse—prolonged, repetitive movement of the muscles and tendons.

What is cold working or work hardening?

What is Strain Hardening / Cold Working / Work Hardening? Strain hardening can also be called cold-working or work-hardening Tempering is the processing applied to the metal Cold working is an important way to increase strength in metals
