Title: A STUDY OF THE METALLURGICAL PROPERTIES THAT ARE NECESSARY FOR SATISFACTORY BEARING PERFORMANCE AND THE DEVELOPMENT OF IMPROVED BEARING ALLOYS FOR SERVICE UP TO 1000 F. Period Covered: January 1, 1956 to March 31, 1957

Abstract

The use of bearings made from hot work steels and other tool steels fn experimental engines has resulted in a few premature engine failures. Unfortunately, very little has been known about the elevated temperature properties such as hot hardness, compressive yield strength, resistance to softening and structural and dimensional stability of these hot work and other tool steels. The work done to obtain these material properties for 29 steels ranging in type from SAE 52100, its modifications, to hot work and other tool steels is reported. An analysis of the data obtained shows that Halmo, VSM, M50, M10, Tl, M2, M1 and two experimental compositions one, Steel B, containing 0.70 C, 4.20 Cr, 0.60 V, and 5.30 Mo, and the other, Steel G, containing 1.31 C, 4.07 Cr, 4.13 V, 5.75 W, and 4.87 Mo, are suitable for elevated temperature aircraft bearing application. From a point of view of temperature range of application these steels have been classified as follows: room temperature up to 700 deg F, Halmo 1; room temperature up to 800 deg F, VSM, M5O, M1O, and Steel B; and room temperature up to 900 deg F, Tl, M2, M1, and Steel G. None of the steelsmore » investigated appeared suitable for application at 1000 deg F. (auth)« less
