Definition of ductility

Ductility is the ductile quality. This adjective can refer to something easygoingcondescending, that admits large mechanical deformations or that can be mechanically extended with wires or threads.

Ductility refers to the property of those materials that, under the action of a strengthThey can be deformed without breaking. These materials, such as certain metals or asphalts, are known as ductile. Instead, materials that do not possess this property are classified as fragile. This means that ductile materials can undergo significant deformation before breaking, while brittle materials break with almost no deformation.

Ductile materials tolerate plastic deformation manufacturing methods and withstand a greater amount of use, since they deform before breaking. It is necessary to apply a large force to break a ductile material: their atoms they can slide over each otherstretching the material without breaking.

The ductility of a material is linked to its ability to deform without breaking.

Differences between ductility and softness

It is important to know how to distinguish between the terms ductile and soft. In the first place, ductility only appears when a particular material is subjected to a force of great magnitude; for example, if a small load is applied, then the material will deform slightly, only yielding and deforming to a much greater degree when pushed to the limit.

The most curious and noteworthy thing is that when this type of material crosses that barrier, in which the force exerted on it is considerable, preserves its integrity and just switch from form.

During a tensile testan experiment that consists of evaluating the properties Related to the resistance of a material, looking for the point at which they break, the ductiles go through a stage of very considerable irreversible deformation that is characterized by a minimum increase in the load to which it is subjected.

Advantages of these materials

For the industry technology and without taking into account certain issues of an economic nature, it is very advantageous to use this type of material for the manufacture of products, since they admit very convenient techniques to obtain certain complex or specific shapes. Regarding its use, its flexibility before being destroyed is its most attractive aspect; a brittle material breaks without giving signs to its user, while in the case of ductile materials, extreme torsion is observed, so that it would be impossible to break them by accident.

The materials ductile are usually used especially in children’s products, seeking to increase not only the durability of objects but also offer greater safety. Opposed to brittleness, ductility ensures that a very pronounced effort is necessary for the break to occur, and prevents the scattering into small fragments, dangerous mainly for children and pets, who tend to put everything in their mouths.

The ductility of a basketball player is given by his ability to contribute in different facets of the game.

Ductility as the ability to perform different tasks

In another sense, ductility is associated with the ability of a person successfully fulfill various tasks or functions. A flexible basketball player, for example, will be able to score points from anywhere on the field, give assists and get rebounds.

A ductile employee is one who can fulfill different obligations within the same business“Juan always surprises me with his ductility: yesterday he sold dozens of products, today he is in charge of paying suppliers and tomorrow he will help me carry out a marketing campaign”“I regret to inform you that we are going to dispense with your services: we need someone with more flexibility for this position”.

There are clear differences between this term and versatilityespecially when used as a description of people: although both refer to the flexibility of an individual, someone versatile is capable of doing many different things, which are generally associated with diverse talents, while a ductile person can attend to many things at the same time without problems, especially because of his good disposition and not necessarily because of his skills.
