Available in PDF, EPUB and Kindle. Book excerpt: Metallic materials for solid-propellant rocketmotor cases in the period 1965-1970 probably will be confined to steel and alloys of titanium and aluminum. Of the three, titanium alloys have the greatest potential on the basis of usable strength-to-density ratio, followed by steel and aluminum alloys. Of the potential steel alloys, by far the most of the current development work is being done on the 18 per cent nickel maraging steels. These steels have the promise of good fracture toughness at high strength levels, and perhaps most important, their heat treatment is favorable for the fabrication of very large boosters, compared to steels that must be austenitized after forming. Of steels that must be austenitized, quenched, and tempered, the modified silico-manganese steels, S5 tool steels, and AISI 9250 spring steel have outstanding potential. Titanium alloys continue to be relatively expensive, but they still have the greatest strengthto-density potential, and, in addition, possess outstanding resistance to corrosion. Development of new titanium alloys is being pursued with the possibility of better titanium alloys being developed. Even though aluminum alloys are not now used in rocket-motor case fabrication, newer alloys are being developed and tested, and may be feasible for such applications in the future.

Book excerpt: Recent studies of the developments in welding steels with yield strengths greater than 150 ksi have included low-alloy martensitic steels, medium-alloy martensitic steels, nickel maraging steels, and bainitic steels. Only weldments from medium-alloy martensitic steels and nickel maraging steels have mechanical properties approaching those of the base plate without a complete postweld heat treatment. The most serious problem with the other steel is low toughness in the weld fusion zone. Adequate weld metal toughness under conditions of elastic strain can be obtarined over the entire 150 to 225 ksi yield-strength range only if the tungsten-arc welding process is used. Processes with higher deposition rates can produce comparable weld deposits only in the lower portion of the range. Above a yield strength of 200 ksi, 18Ni maraging steel weldments have the best combination of strength and toughness. Below 200 ksi, the HP 9-4-25 medium-alloy martensitic steel and 12Ni maraging steel weldments have nearly equal properties.
