Immersion cleaning aided by ultrasonic waves which cause microagitation.
A nondestructive method of testing metal for flaws based on the fact that ultrasonic waves are reflected and refracted at the boundaries of a solid medium. Ultrasonic testing is used to detect flaws in materials.
Part of a mold or die requiring a drawback. See Drawback.
A wild steel insufficiently deoxidized so that it evolves gas and blowholes during solidification. See Killed Steel.
Upper Yield Point (Also Yield Point)
Denoted in yield point phenomenon as a distinct break from the elastic region accompanied by a drop in load, yet prior to plastic deformation in the stress-strain curve in a low-carbon steel.
An addition to any flask part to increase height or depth.
A thermosetting product of condensation from urea or thio-urea and formaldehyde, soluble in water and used as a sand binder in core and mold compounds.
