Book Description
To aid in quick identification and easy location of specific technical data and information in the various reports and memoranda which have been prepared and distributed by the Defense Metals Information Center, as well as by DMIC's forerunner, the Titanium Metallurgical Laboratory, a classification by major subject matter was prepared. The classification covers reports through DMIC Report 193 and memoranda through DMIC Memorandum 183. (Author).

Book Description
A review of machining damage effects in beryllium was made. Surface damage is caused by twinning and microcracking as a result of various machining operations. Twinning is a result of surface working while microcracks initiate at intersections of twins and grain boundaries, at twin-matrix interfaces, at impurity particles, and in heavily twinned regions. These phenomena may be due to residual stresses in wrought products as well as machining parameters such as tool type, feed, and speed and depth of cut. The loss of mechanical properties due to machining damage is reviewed. Also presented is a study of surface damage actually encountered with machining of the shingles for the Gemini spacecraft.

Book Description
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.
