Why edge dislocation moves faster than screw dislocations?
Edge dislocations move faster than screw dislocations because edge dislocations have higher resolved shear stress on their slip plane, allowing them to move more easily through a material. Screw dislocations, on the other hand, require the motion of multiple atoms to move, causing them to move more slowly than edge dislocations.
Where defects can occur in crystal structures?
Within a crystal there are point defects and line defects; point defects are missing or extra lattice points within the crystal lattice (vacancies or interstitials), line defects may be due to an 'extra' half lattice plane within the crystal. The end of a line defect plane is known as an edge dislocation, screw dislocations occur where part of a crystal is displaced over one lattice direction and is therefore twisted. Dislocation loops can occur where an edge and a screw dislocation intersect.
Is there a difference between edge triggering and pulse triggering?
Yes, there is a difference between edge triggering and pulse triggering. Edge triggering occurs when a circuit changes state based on the transition of an input signal (e.g., from low to high or high to low). Pulse triggering, on the other hand, involves triggering a circuit based on the detection of a specific pulse width within the input signal.
Explain how a wedge and a screw are related to the inclined plane?
A wedge is a type of inclined plane that has two inclined surfaces meeting at a sharp edge. The screw is a type of inclined plane wrapped around a cylindrical shaft. Both the wedge and the screw utilize the principle of an inclined plane to multiply force and make it easier to perform tasks like splitting wood with a wedge or holding materials together with a screw.
How screw and wedge related to inclined plane?
A screw is a type of inclined plane wrapped around a cylindrical shaft. When the screw is rotated, it moves up or down along the inclined plane, allowing it to lift or lower objects. A wedge is also a type of inclined plane, but it has two sloping surfaces meeting at a sharp edge, used to separate or secure objects by applying force.
Why edge dislocation moves faster than screw dislocations?
Edge dislocations move faster than screw dislocations because edge dislocations have higher resolved shear stress on their slip plane, allowing them to move more easily through a material. Screw dislocations, on the other hand, require the motion of multiple atoms to move, causing them to move more slowly than edge dislocations.
What is difference between cross slip Vs dislocation climb?
the natur of doublecross slip of scrow dislocations as in duced by a locked parallel scrow dislocation that of edge dislocations a sin duced by locked edge dislocation through climb and that of the cross climb of edge dislocations os induced by another edge dislocation through slip are studied in the light of the interaction of the mutual stress fields of the dislocations
What is difference between cross slip vs slip?
Dislocations move because the resolved shear stress (Schmidfactor) is sufficient high enough to activate the glide system in which the slip plane lies. (slip) Screw-dislocations in fact are able to move from one slip plane to another parallel plane (burgers vector does not change!). In a fcc lattice a $dislocation may change the (111) plane to (1 -1 1) plane due to local stresses. (cross slip) Edge dislocations can change their planes too. It is a thermally activated process which is called climb (vacancy flux).
What is difference between edge and corners in a shape?
Two corners make up an edge.
What is the difference between a edge and side?
A side is basically a geometrical shape; an edge is where two sides meet.
What is the difference between side and edge?
A side is basically a geometric shape; and edge is where two sides met.
What is the difference between a vertice and an edge?
ask ur math teacher ;)
What is the difference between a papaya's leaf and rambutan leaf?
the papaya leaf have a entire edge while the rambutan leaf have a jagged edge
What is the difference between a vertex and an edge?
An edge is where two faces of a three dimensional figure meet. An vertex is where three edges meet.
What is the difference between a triple toe a triple lutz a triple loop and a triple flip?
One is on an inside edge and one is on an outside edge!
What is the difference between single and double edged swords?
One cutting edge vs two
What is the difference between securities and gilt-edge securities?
Gilt-edge securities are those considered the safest investments. If they were stocks, they'd be called Blue Chips.
