(UT) ✔Correct Answer-Radiographic Testing
What will nonmetallic inclusions look like in an ingot? ✔Correct Answer-Irregular
Discontinuities
What shape are porosity found to have? ✔Correct Answer-Round in Shape
What are porosity's and nonmetallic inclusions ✔Correct Answer-Discontinuities
Does the "hot top" eliminate all the nonmetallic inclusions, has-bubble porosity, and pipe?
✔Correct Answer-No
Would cropping the top of the ingot remove many discontinuities? ✔Correct Answer-Yes
Cropping will eliminate all of the "pipe" in the ingot except in those cases where intermittent
shrinkage cavities extend deep in the ingot. But are all discontinuities eliminated by cropping?
✔Correct Answer-No
Nondestructive tests are methods of detecting interruptions in the normal or physical structure
of _________? ✔Correct Answer-An article
Any crack, break, or flaw in the continuity of the physical structure of an article is
called__________? ✔Correct Answer-A discontinuity
Many discontinuities have their origin in the refining process and are in the molten metal
poured into the ___________ mold. ✔Correct Answer-Ingot
Slag impurities are not entirely in the refining process and are found in the ingot as foreign
material called _________ inclusions. ✔Correct Answer-Nonmetallic
, Nonmetallic inclusions are ragged when they harden and take _________ shape. ✔Correct
Answer-An irregular
Due to the refining process itself, all of the material forming gas is not removed from the molten
metal. This causes entrapped gas bubbles to form which are called? ✔Correct Answer-
Porosity
Gas-bubble porosity in the ingot is like bubbles in a bottle of pop. When the ingot hardens, the
porosity takes on the shape of the gas bubbles that are __________ or nearly ____________.
✔Correct Answer-Round, Round
Another discontinuity is formed as the molten metal shrinks as it hardens. As a result, the top of
the ingot has_________. ✔Correct Answer-Shrinkage
Due to the shape of some ingot molds, the shrinkage depression can be severe, extending deep
into the center of the ingot. This type of depression is called ____________________.
✔Correct Answer-Pipe
Most ingot molds have reservoirs called a "hot top" to absorb as much of the pipe, porosity, and
nonmetallic ___________________ as possible. ✔Correct Answer-Inclusions
Pipe, porosity, and nonmetallic inclusions are all interruptions in the normal physical structure
of the ingot and are therefore____________. ✔Correct Answer-Discontinuities
If the billet is rolled a second time to increase the length, what will happen to the crystal
structure? ✔Correct Answer-The crystals will break into smaller crystals and the grain will be
fine
How do nonmetallic inclusion act as it is pressed between the rollers. ✔Correct Answer-It
would spread in all directions, but mainly in the direction of roll
Which way does the grain form in the bar being rolled? ✔Correct Answer-Through the length
of the bar
What do you think would happen to porosity in the slab being rolled into sheet or plate
material? ✔Correct Answer-Porosity would cause a lamination
It extends in the direction of grain formation. ✔Correct Answer-A description of how a
nonmetallic inclusion reacts in a billet being rolled into bar stock
Yes ✔Correct Answer-Are seams (cracks) discontinuities?
