What hardness testing method uses a penetrator or indenter to make an impression in a piece of material and then uses the depth of the indentation to calculate a hardness value?
The hardness testing method that uses a penetrator or indenter to make an impression in a material and calculates hardness based on the depth of the indentation is called the Vickers hardness test. In this method, a diamond pyramid indenter presses into the material, and the size of the resulting indentation is measured to determine the Vickers hardness number (HV). This test is applicable to a wide range of materials and provides a continuous scale for hardness values.
What is the minimum hardness value for IS 1570 Gr 20C8 material?
The minimum hardness value for IS 1570 Gr 20C8 material is typically around 197 HB.
What is the hardness of the noble gases?
it has no hardness ohk... then what exactly do you call solid oxygen?
How do you use a Shore scleroscope hardness test?
To perform a Shore scleroscope hardness test, align the indenter tip perpendicularly to the material surface and release it, allowing it to rebound. Measure the hardness reading indicated on the dial on the device. Repeat this process at various locations on the material to get an average hardness value.
What is the hardness value for carbon?
the hardness vlaue of carbon very much depends on the value of the hardness of the carbon. if it is a high value then the hardness is high however if it is a low value then it is a low hardness helpful??? :D
Normal hardness value of cast iron used in lathe bed?
In brinell scale ,the hardness value is 180
If a material has a hardness of 8 can it not be scratched by a material with a hardness of 7?
Yes, a material with a hardness of 8 can scratch a material with a hardness of 7, but not the other way around. Hardness is a measure of a material's resistance to scratching, so a material with a higher hardness value can scratch a material with a lower hardness value.

What is the hardness of bromine?
Bromine's hardness is not typically measured, as it is a liquid at room temperature and does not possess a defined hardness value like solid materials.
What is the hardness for chlorine?
It is a gas so it doesn't have a hardness unless in solid state
Why hardness value is very important in the metallurgy study?
The hardness value is important because during metallurgy, people can make accurate deductions as to the kind of work the metals can be used for. Hard metals can be used to make knives and propeller rotors.
How do you determine the hardness of a mineral?
The hardness of a mineral is determined by scratching it with materials of known hardness, such as a fingernail, a copper penny, a steel nail, or a piece of glass. The mineral is assigned a hardness value based on which material can scratch it. This is known as the Mohs scale of hardness.
What is the adjective for hardness?
An adjective--a hard surface.An adverb--work hard.
Describe what would happen if you rubbed a mineral with a mohs hardness value of 7 against a mineral with a value of 5?
The mineral with a Mohs hardness value of 7 (such as quartz) would scratch the mineral with a value of 5 (such as apatite). This is because a mineral can scratch any other mineral with a lower Mohs hardness value.
