What is difference between sessile dislocation and glissile dislocation?
a sessile dislocation has a burger's vector that does notlie in the primary slip plane of the crystal, so it is immobile.a glissile dislocation has a burger's vector that doeslie in the primary slip plane of the crystal and thus is able to move in that plane.
What is the relationship between resolved shear stress and critical resolved shear stress in materials science?
In materials science, the relationship between resolved shear stress and critical resolved shear stress is that the critical resolved shear stress is the minimum amount of shear stress needed to cause dislocation movement in a material. Resolved shear stress is the component of an applied stress that acts in the direction of dislocation movement. When the resolved shear stress exceeds the critical resolved shear stress, dislocations can move and deformation occurs in the material.
What is material frequency?
Material frequency refers to how often a particular material or substance is used or encountered in a given context, such as in a specific industry, product design, or research material. It is used to determine the prevalence and importance of a material in a certain field.
What is the symptom of dislocation?
the joint almost always swells significantly and feels painful when pressure is applied (point tenderness). If trauma to the joint causing the dislocation or subluxation is violent in nature, small chips of bone can be torn away
Which term describes the attempted reduction or restoration of a fracture or dislocation with application of manually applied force?
Closed reduction is the term used to describe the attempted reduction or restoration of a fracture or dislocation with the application of manually applied force, without the need for surgery or incision.
Why Strength and hardness of material are increased in cold working?
The reason that the hardness increases as the cold working increases is because of defects. Before the reduction, or cold working, the lattice of the material has a virtually defect free, or dislocation free, pattern. The cold working increases the amount of dislocations, and because of this, the material becomes more resistant to additional deformations. This manifests itself, most noticeably, as resistance to plastic deformations. Microscopically, this explained by the two types of dislocation shifts. Dislocation boundaries can move within the plane of dislocation relatively easily; this is known as a glide. However, when a dislocation boundary is moved up or down, out of the plane of dislocation, it takes much more energy. When a material becomes saturated with dislocations, any new dislocation will inevitably have to shift some dislocation boundaries out of their plane. This is known as a climb. Since climbs require more energy, more force is needed to plastically deform the material, i.e. the material becomes harder. The more dislocations a material has, the more climbs are done to achieve this new dislocation, making it harder to plastically deform a material. So the more cold worked the material is, the more climbs are needed, meaning that more energy is needed to deform the material. I'm pretty sure this is right -SMG
What is dislocation density?
Dislocation density is the areal density of dislocations intersecting a plain, usually the free surface, given as number per cm2. It may also be the volume density of dislocation line segments, given as the total length of dislocations divided by the containing volume (also 1/cm2), but this is rarely used in semiconductor physics, and more frequently found in engineering. Dislocation density is typically measured by etching the free surface to form pits around the location at which the dislocation breeches the surface, and is termed etch pit density, or EPD.
What is a frank reed dislocation?
A Frank-Read dislocation is a type of dislocation that forms when two dislocations with opposite line directions interact and create a new 'jogged' dislocation. This type of dislocation can contribute to the hardening of materials through dislocation tangles and obstacles in the crystal structure.
What is art elongation the importance of it and the history?
What is the importance of elongation of a material?
When was Human Dislocation created?
Human Dislocation was created in 1997.
What is the most common type of dislocation?
Hip joint dislocation
Is burger vector and dislocation line both lie in one plane in sessile dislocation?
>> Burger vector and dislocation line both not lie in single active slip plane in sessile dislocation.
What is another name for dislocation?
Another name for dislocation is luxation.
What is importance of material management?
There are many great importance reasons for the management of material. This management leads to more effective and efficient decisions.
When was Dislocation Blues created?
Dislocation Blues was created on 2007-04-03.
What is the difference between a dislocation and a subluxation?
Subluxation is a partial dislocation. A dislocation is a severe injury in which the articular surfaces of joint is no longer in contact & a subluxation is a partial or incomplete displacement of the joint surface.
What are the signs of a failed knee transplant?
Dislocation. This may be due to muscle weakness, or knee cap fracture. The revision is replacing the insert, to a thicker material.
