Are sproede materials deformable

brittleness

 

The brittleness states the extent to which a material can be plastically deformed before it breaks. This material property can be determined in the tensile test:

The brittleness of most materials increases with it sinkingTemperature. However, there are exceptions such as with austenitic metals. The fracture mechanics of brittle materials, such as brittle metals, have the opposite property of toughness.

Embrittlement

Various factors can cause a material to become more brittle than when new, due to the process of Embrittlement.

  • Plastics containing plasticizers become brittle when the plasticizer escapes from them. The escape is promoted by environmental factors such as high temperatures or strong solar radiation ("UV"), whereby the vapor pressure of the plasticizer increases. <-? ->
  • Disturbances in the crystal lattice: under the influence of radioactive radiation, iron and steel become brittle. Iron atoms are pushed from their lattice sites by neutrons, causing a cascade of collisions that form clusters of defects in the lattice.
  • Storage of hydrogen in some types of steel leads to hydrogen embrittlement, which in turn is based on lattice defects.

Figurative meaning

In the case of people, the concept of brittleness is understood in a figurative sense to mean that the person in question is not easily accessible, communicative or emotionally not particularly open-minded, or introverted. The deformability of the material is thus transferred to a person and their communicative and emotional adaptability. A brittle person is “too inflexible” for an intensive exchange of thoughts or feelings.
