Good work Ken.

These explosive bonding process have been used to bond very dissimilar

metals. Titainium cladding is done using this process as well. Worth looking
into.

 Paul and Bill,
Titanium may be better in regard to expansion rates but doesn't wear too
well without nitrite surfacing, I'm let to believe.

The more I think about this idea the better I like it.

The steel sheet could be heat treated 4130 and the aluminum cladding dead soft 1100.

For a rotor housing you might be able to explosively form the steel into the trochoid
shape from round tube while simultaneously bonding it to the aluminum.

This could be a very low cost manufacturing method if automated. Could also
be a cost breakthrough in building aluminum rotary engine. I am going to continue
to look into this.
