This photomicrograph was the Grand Prize Winner in the 1962 Metallographic exhibit, at the National Metal Congress and Exposition in New York City. This photograph by Don Medellin was awarded "Best in Class" for Surface Coatings and Surface Phenomena, and "best in Show" for all classes. It was part of the work on the interaction of electron beams with materials, being carried out by Dr. Jack I. Medoff, Research Specialist, in the Material Sciences Section of the N.A.A. Autonetics Research Center in Anaheim.

Why build Independence Hall? We cannot say it is better than did Mr. Walter Knott, "Our Declaration of Independence was worked out and signed there by 56 brave men who closed it with these famous words: 'And for the support of this Declaration, with a firm reliance on the protection of Divine Providence, we mutually pledge to each other our Lives, our Fortunes and out sacred Honor.'  Truly great men. Then after nearly 10 years of war, when victory finally came, other great, and I believe divinely guided, men again met at Independence Hall to decide what kind of government we should have. They, too, produced one of the world's outstanding documents - Our Constitution. These two documents are among the greatest conceived by man. They have changed the course of liberty.

Independence Hall is a beautiful and stately building, and one all of us at the farm will be proud of. I think, like starting Ghost Town twenty-five years ago, that building Independence Hall will be a milestone in the history of the Farm. It will be our reminder of some of the most crucial events in all history."

We wish to express our gratitude to Mr. and Mrs. Walter Knott for providing Southern California with this reminder of our priceless heritage - also to Mr. Davison and staff for their assistance in making this photograph possible.

The photograph on the cover, illustrating fatigue crack branching in a 2219-T851 Aluminum plate, is a scanning electron micrograph of a metallographically prepared sample. The primary crack is in the transverse direction, resulting from the longitudinal loading of the specimen. The secondary cracks are in the longitudinal direction and tend to propagate intergranularly along stringers of second phase particles. Secondary cracking occurs intermittently as the primary crack continues to grow. The energy expended in generating these secondary cracks probably results in a lowered crack growth rate than would be observed if crack branching did not occur. This sample was part of a study being conducted on the fatigue crack growth characteristics of aluminum alloys by the B-1 division of Rockwell International in conjunction with Scanning Electron Analysis Laboratories, Inc. The micrograph was taken by SCANNING ELECTRON ANALYSIS LABORATORIES, INC., who also sponsored the cover.

AMS, founded in 1979, is associated with two other specialized metal heat treating firms - H&H Heat Treating, a rapidly growing heat treating center for the hi-temperature and exotic metals, titanium, and stainless steel alloys; and Aluminum Heat Treaters of America, Inc. with complete heat treat facilities for the aluminum processing industry.

These three firms are uniquely organized and qualified to supply a versatile metals testing and thermal processing function for the West Coast.

METALS BORN TO FLY

You'll find our hard alloy aluminum and titanium extrusions in commercial and military airframes and other high performance parts - large and small, simple and complex.

Our smallest presses can extrude shapes less than 13 millimeters across. our giant 14,500 ton press can produce aluminum pieces as big as 30 inches. It is one of the largest in the world.

We're outfitting the big press to handle titanium extrusion billet, too, as part of a $100 million development program. The large structural shapes that result will replace many heavy steel parts now in use, or will save the time of welding together smaller pieces.

We are committed to advancing the state of the aviation art, by providing solutions in metal, today and for years to come.

SMC has assembled the best personnel and equipment needed to maintain it;s high standards Consequently, SMC is finding that during this revolutionary period, quality and service are still the formula for success.

All space shuttle guidance rocket chambers (The Columbium R.C.S. units) manufactured by Marquardt have been process through the SMC furnaces with greater than 99.999% accuracy and reliability in over 5,000 cycles. The processing of Columbium within acceptable cleanliness and property tolerances is probably the most difficult heat treatment task.

SMC is truly the heater to the stars and beyond?

By the early 1970's, Shultz Steel Company had gained a position as an important producer of complex die forgings for the Aerospace Industry. Open die forgings are very important in the prototype and early productions stages of aircraft because they can be made with little or no tooling, thereby permitting small productions runs and design flexibility.

The ERC features many "unique" recycled materials, such as concrete reinforcement bars made of recycled steel from weapons confiscated the the Los Angeles Sheriff's Department; a lobby floor made of wood recovered from a condemned turn-of-the century Banana Republic ware house in San Francisco; a wall made of recycled aircraft aluminum; and sections of a stairway used in the popular Warner Bros. film "Disclosure".
