DEVELOPMENTS resulting from research inspired by the war's demands for greater speed, larger volume, and material and labor conservation, have led to the manufacture of many airplane parts by the impact-extrusion method. Where the previous methods called for casting, forging, or machining from solid stock, research has developed ways to use the impact-extrusion method that are more rapid and economical. Aluminum and aluminum alloys can be extruded by this method and their size is limited only by the power of the press available for the work. Small parts are produced in large quantities by the use of multiple dies. Experiments have established the pressures required to form these materials by the impact-extrusion method, complicated designs and shapes can be easily produced, and there seems to be no limit to the height to which the metal will flow, if the required force is applied to the tools.

ALTHOUGH shaving had already become a common method of finishing spur and helical gears in the automotive industry before the war, there were many problems that had to be solved before this method could be applied to aircraft-engine gears. The major objection of the aircraft industry to shaving has been the probability of distortion during heat-treatment subsequent to finishing the tooth form. Mr. Harris suggests that the heat-treatment procedure be changed to make expansion more uniform, and then an allowance be introduced in cutting the gear originally to compensate for this uniform expansion. Another objection to shaving has been the probability of highly concentrated stresses due to cutter marks and the line of demarcation between the hobbed and shaved contour in the tooth fillet. Mr. Harris proposes a form of hob for giving smooth fillet contours that will blend with the shaved active profile of the gear. The author also discusses the types of errors that might occur in the gear before shaving and be only partially corrected.

AMS5042B
This specification has been declared “NONCURRENT” by the Aerospace Materials Division, SAE, as of August 2009. It is recommended, therefore, that this specification not be specified for new designs. “NONCURRENT” refers to those specifications which have previously been widely used and which may be required for production or processing of existing designs in the future. The Aerospace Materials Division, however, does not recommend these specifications for future use in new designs. “NONCURRENT” specifications are available from SAE upon request.

AMS5575B
This specification covers a corrosion and heat-resistant steel in the form of welded tubing.
1942-12-01
Standard
AMS5570C
This specification covers a corrosion and heat resistant steel in the form of seamless tubing. This tubing has been used typically for parts requiring both corrosion and heat resistance, especially when such parts are welded during fabrication, and also for parts requiring oxidation resistance up to 1500 degrees F (816 degrees C) but useful at that temperature only when stresses are low; usage is not limited to such applications.

AMS6350
This specification covers an aircraft-quality, low-alloy steel in the form of sheet, strip, and plate.

Standard
AMS6352A
This specification covers an aircraft quality, low alloy steel in the form of sheet, strip, and plate. These products have been used typically for heat treated parts and structures that may require welding during fabrication, but usage is not limited to such applications. It may be through-hardened to a minimum tensile strength of 180 ksi (1241 MPa) in sections 0.125 inch (3.18 mm) and under in nominal thickness and proportionately lower strength in heavier section thicknesses.
