Why pearlite makes steel harder?
Because Martensite transformation is almost instantaneous, the Martensite has the identical composition of the parent phase. Formation of Martensite involves a transformation from a body-centered cubic structure to body-centered tetragonal structure. The large increase in volume that results creates a highly stressed structure.
How do you use decalcification in a sentence?
Decalcification is the process of losing calcium in a bone. Decalcification makes the bone soft and brittle.
Is rusting useful or harmful?
harmful as it makes the metal brittle
What does bleach do to bone?
Removes the phosphorous. It makes them very brittle.
What is a sentence with the word brittle?
The tea cup is fragile so please dont drop it.
Treating all aspects of culture equally makes anthropology?
Treating all aspects of culture equally makes anthropology more inclusive and comprehensive, allowing for a more holistic understanding of human societies. It helps to avoid bias and ethnocentrism, enabling researchers to appreciate diverse cultural practices and beliefs.
Osteoprosis is a condition that makes bones?
Osteoporosis is a condition that causes bones to be weak and brittle.
Does bleaching your hair make it appear longer?
no it makes it look dry and brittle after a while
How do you control the properties of steel?
Properties of steel can be influenced by several factors:CompositionIncreasing the amount of carbon in steel increases its strength and hardness. Carbon in the form of carbides (like Fe-Fe3C), which are hard themselves and act as strengthening agents in steel alloys through dispersion strengthening. Increasing carbon content also has the general affect of lowering the temperature. Looking at the phase diagram is helpful in understanding this effect: iron (Fe) has a higher temperature than iron-carbide (Fe3C).Heat TreatmentsHeat treating affects strength, ductility, hardness, or impact resistance. Annealing, normalizing, etc. affect the microstructure of steel. Steel can be made into various microstructures - martensite, bainite, pearlite, cementite, ferrite (in no particular order) - each of which has different properties. Martensite is the strongest microstructure, with increased ductility through tempering to tempered martensite. Tempering encourages carbon diffusion, resulting in improved strength and ductility as the trapped carbon from the rapid quench to martensite is allowed to diffuse.Surface TreatmentsIf you're talking about a part, then surface treatments will affect the surface hardness. For example, adding Zinc will increase the strength and corrosion resistance of the part. Case hardening is another way to strengthen the exterior of the specimen.Note: Strength and ductility for steels are usually inversely related, so improving one typically means sacrificing the other (i.e. increasing the strength usually makes steel more brittle, therefore less ductile). The deciding factor then typically is application.
What layer of the earth makes these plates up?
The lithosphere (which is composed of the crust and solid brittle upper mantle) makes up the Earth's tectonic plates.
Why does metal get rusty?
The metal reacts with oxygen, causing a chemical reaction which makes it turn brittle and orange
What happens if too much calcium is deposited in the bone?
Too much calcium makes the bones brittle.
