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
Pipe class is a collection of most compatible components considering dimensional and material properties for the intended service over a range on pressure and temperature specified.
Metalurgy
The definition of a material world is a fake world.
Carbon-containing material
Define material budgets
Mainly metalurgy, civil engineering, metal working.
Improvements in metalurgy have allowed higher pressure cartridges to be developed.
characteristic or functionality of a material = property of a material
glittering material
A material object is a fetish.
Metalurgy, irrigation, roofing tiles, roads and bridges, jewelry, trade.
A material that does not contain iron.
It means the material is easy to be burnt and should be kept away from fire.
