Abstract: A method of conditioning type 18-8 stainless steel material for cold work by subjecting the material to a mechanical deforming operation of less than 85% above the Md30 temperature. This processing enables the stainless steel, upon cold work, to transform the austenite to martensite at a much higher rate than in unconditioned stainless steel so that much higher tensile strengths may be achieved with much lower amounts of cold work. In another embodiment of the invention, a method of producing a type 18-8 stainless steel with a tensile strength of over 325,000 psi. at about a 60% cold work level is achieved.

Abstract: AN ULTRAHIGH STRENGTH MATERIAL MADE FROM ORDINARY 188 STAINLESS STEEL HAS A TENSIL STRENGTH IN EXCESS OF 400,000 P.S.I. THE METHOD OF PRODUCING THE ULTRAHIGH STRENGTH IS ACCOMPLISHED BY THERMO-MECHANICAL OPERATIONS. THE MATERIAL CAN HAVE ANY DESIRED GEOMETRIC CROSS SECTION CONFIGURATION AND IS ADAPTABLE FOR USE AS A SPRING MATERIAL.

Abstract: "ENERGY ABSORBING SUPPORT" An energy absorbing support formed of a composite coil defining a core and a tubular sheath with the sheath being formed of a material having a higher elastic yield strain limit than that of the core. The coil defines a first portion and a second portion with a support of the coil disposed intermediate the first and second portions. Structure is provided for applying a preselected preload to the coil. The coil materials are preselected to maintain elastic and damping characteristics at cryogenic temperatures, such as below -150.degree.F. The support is adapted for use in rigorous environments such as encountered in the space shuttle and the like, and provides lightweight, long life, resilient support of critical elements, such as piping and the like, therein.
