This book was released on 1964 with total page 1 pages. Available in PDF, EPUB and Kindle. Book excerpt: This memorandum deals with the mechanical and physical properties of three superalloys for elevated-temperature service. One of these, MAR-M200, is a nickel-base alloy and the other two, MAR-M302 and MAR-M322, are cobaltbase alloys. A request for data was made to several laboratories known to have tested experimental lots of the three alloys. The first section (Chemical Compositions and Physical Properties) contains general information on all three alloys. The second section (Data Curves) contains plots of the raw mechanical- and physical-property data. The third section contains the raw-data sheets as obtained from the contributors. The MAR-M200 alloy was designed for severe operating conditions primarily as blades and vanes in gas-turbine applications. The MAR-M302 alloy was designed primarily for use as a first-stage nozzle guidevane material in advanced engines. The MAR-M322 alloy may find use as turbine-blade material as well as a guidevane alloy because of its increased strength. (Author).

Book excerpt: Porosity in fusion welds in titanium has been encountered to some extent in all programs using this joining method. While measures to control cleanliness and to employ good welding techniques have successfully reduced the occurrence of porosity, specific indentification of the various causes of porosity is still lacking. Some factors suspected of causing porosity in titanium welds are hydrogen, cleanliness of joint area, contamination in filler wire, and welding procedures and techniques.

Available in PDF, EPUB and Kindle. Book excerpt: The memorandum summarizes the available information on the compatibility of liquid rocket propellants with prominent materials of construction. Fuels and oxidizers of current interest are discussed. The corrosion data which are presented will apply to storing, handling, and control equipment outside of missiles and to missile components excluding combustion chamber. The compatibility of materials with reaction products in combustion chambers, nozzles, etc., is not considered. Included in the summary are data for many nonmetallic materials. The memorandum is subdivided into sections according to the propellant. Each material of construction is rated for a given medium as belonging to one of four classes, based primarily upon corrosion resistance. Consideration also is given to such factors as catalytic decomposition and sensitivity to impact.

Available in PDF, EPUB and Kindle. Book excerpt: 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.
