[TheForge] Science fair project

Thu Nov 7 08:27:01 2002

Not a bad idea.  One use to which clay has been put is to test what =
happens to the steel during various operations.  To do this, you make thin =
layers of colored clay and press them together to get a striped "billet" =
(like pattern welding, but with clay).  Then you slice them lengthwise =
across the layers and put them together the other way to get a billet =
that's "checkerboard" in cross section. =20

Now you use that checkerboard billet in various forging operations.  I =
have a book somewhere that shows the results.  I'll bet most of you hadn't =
thought about where the steel goes in such operation!  For example, if you =
upset a bar by placing the hot end against the anvil and hammering, you =
get no mushrooming of the end - the checkerboard pattern remains as in the =
original bar.  It is the material behind this that spreads.

Once again, the catch is to turn this into an EXPERIMENT.  Demonstrations =
don't (or shouldn't) win science fair competitions.  So hypothesize what =
will happen to the steel in a billet in a certain forging operation, then =
test it.

By the way, this sort of experiment could provide very useful results for =
people working pattern-welded billets who wish to give rise "natrually" to =
elaborate patterns.  I'm sure some folks have already studied this, but I =
don't know of any books on the subject.  (But then I'm not doing pattern-we=
lding!)

Several people have done demos using clay instead of hot iron. This
can be very effective.
