Hi,i am Engineer Naveed.My favorite subjects are ...
The concept of fatigue is very simple, when a motion is repeated, the object that is doing the work becomes weak. For example, when you run, your leg and other muscles of your body become weak, not always to the point where you can't move them anymore, but there is a noticeable decrease in ...
A fracture is the separation of an object or material into two, or more, pieces under the action of stress.The fracture of a solid almost always occurs due to the development of certain displacement discontinuity surfaces within the solid. If a displacement develops in this case perpendicular to ...
Cleavage, in structural geology and petrology, describes a type of planar rock feature that develops as a result of deformation and metamorphism.The degree of deformation and metamorphism along with rock type determines the kind of cleavage feature that develops. Generally these structures are ...
The reduction in diameter that occurs as a sample material is subjected to tensile stresses. Necking, in engineering or materials science, is a mode of tensile deformation where relatively large amounts of strain localize disproportionately in a small region of the material.
The chemical or electrochemical reaction between a material, usually a metal, and its environment that produces a deterioration of the material and its properties.
Segregation in materials refers to the enrichment of a material constituent at a free surface or an internal interface of a material. In a polycrystalline solid, a segregation site can be a dislocation, grain boundary, stacking fault, or an interface with a precipitate or secondary phase within the ...
Manganese in the range of 1.65 to 2 percent is added to improve tensile strength,hardness,harden ability and hot workability of steel.Manganese steel with high carbon 1.1 to 1.4 percent and high manganese 11 ti 14 percent steel having excellent abrasion resistance in heat treated condition.
Silicon steels contains approximate 0.05 percent carbon and 0.10 percent manganese and 0.50 to 1 percent silicon and less than 0.02 percent sulphur and phosphorus.Silicon steels usually have better elastic,electrical and manganese properties.Additionally,these steels exhibit enhanced resistance to ...
