The determination here was
dismissal
by the judge, based on the fact that the
alloy under discussion was already well
known and in production prior to any
alloy suggested or invented by Crucible.
Rather than “leaving the invention of
the Ti-6Al-4V unsettled” as concluded
in the article, the patent granted to
Watertown Arsenal (No. 2,906,654)
was indeed a composition patent, and
not a process patent as implied. This
too is well documented in the mono-
graph and includes data derived from
arc melted ingots produced for Water-
town by purchase orders to National
Research Corp. in Cambridge, Mass.
This confused history evolved as
a result of the widespread announce-
ment of the Watertown development
in 1954 followed by five years of quiet
regarding any government patent
application. During that quiet time,
Ti-6Al-4V production and application
grew tremendously, boosted by imme-
diate use in the J-57 engine for the
highly secret U-2 spy plane. Because
there was no word regarding any gov-
ernment patent application, both Bat-
telle (Rem-Cru) and ARF thought they
may have fallen upon rights to this
valuable alloy. Both claimed ternary
alloys of Ti-Al-V and each tried to reach
back to earliest conception. Their com-
peting conception dates were close and
neither had produced an alloy contain-
ing 6Al-4V. The earlier work and patent
application at Watertown displayed
data that any higher Al would not
produce the required ductility for the
application, and any higher V would not
offer the necessary weldability; lower
content of either would not achieve
optimum strength. Original data from
the patent application is reported in the
monograph.
The failure to mention the U-2
project and the related Pratt & Whitney
J-57 engine that enabled its success is a
major oversight. Chapter 8 of themono-
graph—A Short Drive to East Hartford,
Connecticut—tells of the top secret
program funded by the CIA to Lockheed
and onto P&W for a new jet engine that
could reach the high altitude required
for the U-2 designed by Kelly Johnson
at the Lockheed Skunk Works. This
endeavor was a top priority and also
top secret. In 1953, I was instructed
to visit P&W to present our complete
results on Ti-6Al-4V alloy and to indi-
cate that we had ordered production
ingots of this alloy from Mallory Sharon
and Titanium Metals Corp. and that a
mil spec had been prepared. It was the
J-57 that made the U-2 possible and it
was the Ti-6Al-4V alloy that made the
J-57 possible. That interesting U-2 story
still has segments that remain secret to
this day.
In my research for further facts
after my startling visit to P&W, I deter-
mined that a top secret program had
existed involving President Dwight
Eisenhower, president James Killian
of MIT, president Edwin Land of Pola-
roid, and CIA director Allen Dulles along
with Lockheed Skunk Works director
Kelly Johnson and P&W. This working
group was called the Killian Panel. It
was the Lockheed design that required
an improved J-57 engine to achieve the
altitude necessary to meet the mission
requirements that would allow Land’s
cameras to photograph the ground
below. And it was the prompt switch at
P&W to Ti-6Al-4V alloy for key compo-
nents that permitted the first real test
flight in August 1955 and the first fly-
over of the Soviet Union in 1956.
This historical note helped me to
better understand why I was instructed
to visit P&W and present the data per-
sonally, while GE, GM-Allison, Boeing,
Lockheed, and others got to review the
detailed Ti-6Al-4V data from the Metal-
lurgical Advisory Committee on Tita-
nium (MACT) report P-13. This relayed
the technical information in response to
their direct letter inquiries prompted by
the press release. I drafted the response
to all of these inquiries, which are also
documented in the monograph.
Now comes the difficult part of
my comments on the history presented
in the April article—the Hickey letter,
which Simcoe describes as “the final
word.” The reader is not told that this
letter was written in 1987, well over
30 years after the invention at Water-
town, yet 12 years before my mono-
graph was published. I researched this
letter as well, but out of respect for
Hal Kessler did not address it in the
1999 monograph. I will now explain
its occurrence. I called Charlie Hickey
and asked how he could say to Kessler
that he was the inventor. Hickey apol-
ogized and explained as follows: In the
course of presenting a technical paper
at a Titanium Development Association
meeting (now ITA) at Annapolis, Md., in
1987, Hickey credited Watertown Arse-
nal and myself as the inventor of the
Ti-6Al-4V alloy. This resulted in a letter
to Hickey from Kessler claiming that
ARF and Harold Kessler invented the
Ti-6Al-4V alloy. Hickey said he avoided
responding to the letter and to repeat
phone calls from Kessler because the
occurrence was so many years before
he or his current colleagues were at
the Arsenal and much was still under
security classification. With the calls
demanding a response becoming both-
ersome, Hickey said he went to his boss
and asked what he should do. His boss
replied, “Tell the pest what he wants
to hear and get him off your back!” On
Kessler’s next call, Hickey did just that
and then got the unexpected request to
put it in writing.
Even the three-sentence Hickey
response (which exists with my mono-
graph files) does not resemble the
description presented in the article
stating that “he (Kessler) was indeed
the inventor” of the alloy. The brief
Hickey letter vaguely referred to the
developers as Watertown and ARF and
references a later contract initiated in
July 1953 and completed in August 1955
from work directed by Don McPherson.
The letter does not even mention Kes-
sler or include the words “indeed” or
“inventor.”
The JOM Monograph entitled “The
Emergence of the Titanium Industry
and the Development of the Ti-6Al-4V
Alloy—Collections and Recollections”
is available from ITA for $10 per copy,
reduced from $45. However, I will per-
sonally cover the costs for the first 50
requests. To obtain a free copy, call ITA
at 303.404.2221.
