My apologies... I got it wrong... it is just the material continually in contact with the flow in a valve.
Thank you anyway...
A material will be graded as brittle when it breaks with only a small amount of strain. Its brittleness is based on the amount of deformation used to break the material.
The definition of theme is an amusement park
A brittle material fractures without haven a large strain on beforehand. Examples are most ceramics, of extremely hard steel. The opposite is ductile.
it is defined is the stress in the material(steel,Al,etc) that will not be exceeded under normal operating condition
Foundry is a technology of casting metals into shapes by melting them into a liquid, pouring the metal in a mold, and removing the mold material or casting after the metal has solidified as it cools.
Metalurgy
The definition of a material world is a fake world.
Carbon-containing material
Define material budgets
a material that occurs naturally in nature
Mainly metalurgy, civil engineering, metal working.
It means material which was not a part of a living organism.
Improvements in metalurgy have allowed higher pressure cartridges to be developed.
The Mohs scale definition of hardness is that a harder material has the ability to scratch a softer material. So (according to the Mohs definition) one material can scratch another one because it is harder.
characteristic or functionality of a material = property of a material
glittering material
A material object is a fetish.
