| Title: | High Temperature Be Panel Development | |
| Author: | R. E. Hardesty, Larry A. Grant and Mark Jensen, Electrofusion Corp. | |
| Abstract: | Beryllium materials have been used for many aerospace applications over the years. Most of these applications have been fairly ambient environments. The work reported in this paper investigated the possibility of fabricating Beryllium panels for high temperature applications up to 1200° F. Joining alloys were reviewed, tested and evaluated for high temperature applications.

| Title: | Fabrication of Stable Lightweight Beryllium Optical Support Structures |
|
| Author: | R. E. Hardesty and Larry A. Grant, Electrofusion Corp. | |
| Abstract: | This paper will describe many recent aerospace applications where Beryllium was successfully used in different types of optical support structures. It discusses how several manufacturing methods, including machining, metallurgical brazing, epoxy bonding and near-net-shape processing were used to produce the desired overall configurations. The installation of non-beryllium inserts is also discussed in detail. Typically made of titanium, these inserts allow the end user to final finish mechanical attach points and optical lapping points, thus circumventing potential toxicity hazards associated with airborne Beryllium particles. Data is also presented about the stress and stability characteristics in some of the more specialized applications, as well as weight and stiffness. Presented at SPIE, 1990 |
