End quenching can change the hardness of metals by introducing different crystal structures. Steel is commonly quenched to introducing martensite, a very hard form of steel crystalline structure.

What is the end result in a chemical change?
The end result in a chemical change is an atom
Is running a mile chemical or physical change?
This is a tough one - I can make a case for both. It could be considered a physical change because at the end of the mile you are the same individual, just one mile away. It could also be considered a chemical change since you are converting ATP to ADP and burning glucose into carbon dioxide and water during the run.
What is the scientific term for the ability to change color?
Camouflaging
What is colourimetric titration?
Titration in which the end point is marked by a color change.
What can be observed about the rate of change of pH of a solution near the end point of titration?
S
What is the ideal critical diameter and can it be determined with a jominy test?
The Jominy Test involves heating a test piece from the steel (25mm diameter and 100mm long) to an austenitising temperature and quenching from one end with a controlled and standardised jet of water. Take a sample from the furnace and place it on the Jominy test fixtures and observe the cooling pattern. After quenching the hardness profile is measured at intervals from the quenched end after the surface has been ground back to remove any effects of decarburisation (0.38mm is removed from the surface). The hardness variation along the test surface is a result of microstructural variation which arises since the cooling rate decreases with distance from the quenched end. The cooling rate along the Jominy test specimen varies from about 225 °C s-1 to 2 °C s-1.
What else could you change to change the pitch?
Put a log under one end.
How could you change a line segmant into a ray?
add one arrow at the end.
What did the 1850 compromise do?
Deal with slavery. They could not agree on how to change or end it, so they did nothing.
What did the compromised of 1850 do?
Deal with slavery. They could not agree on how to change or end it, so they did nothing.
What does the Moh's hardness scale show?
The hardness of different minerals and things. Like talc would be at one end of the spectrum, and a diamond would be at the other (since a diamond is the hardest mineral known).
How could you change a line into a line segment?
Add two end points to the line and label them.
How could you change 7x8 to make a true number sentence?
Put a equal sign at the end
Is quench a noun verb adjective or adverb?
The word 'quench' is a verb (quench, quenches, quenching, quenched); to put out, extinguish; to satisfy a thirst; to bring to an end by satisfying, damping, cooling, or decreasing.
What might happen after the planets align?
Some theories state that weather could change and others say that it could be the end of the world. No one is sure about this.
What does it mean if you are dead in your dream?
In dreams, death symbolizes significant change. So this dream could represent the end (death) of one's student life at graduation, or even the end of this current school year. It could mean the end of a job or the fulfillment of a contract, etc. Other elements in the dream may provide hints as to the change represented.
What is the Hardness of 1018 carbon steel?
Between 121-137 on the Brinell hardness scale - which is quite soft. The end parts are generally case-hardened before use to 60+ Rockwell "C".
