Surface fatigue life of M50NiL and AISI 9310 spur gears and R C bars by Dennis P Townsend( Book )
2 editions published in 1991 in English and held by 79 WorldCat member libraries worldwide
Spur gear endurance tests and rolling-element surface fatigue tests were conducted to investigate vacuum-induction-melted, vacuum-arc-remelted (VIM- VAR) M50NiL steel for use as a gear steel in advanced aircraft applications, to determine its endurance characteristics, and to compare the results with those for standard VAR and VIM-VAR AISI 9310 gear material. Tests were conducted with spur gears and rolling-contact bars manufactured from VIM-VAR M50NiL and VAR and VIM-VAR AISI 9310. The gear pitch diameter was 8.9 cm (3.5 in.). Gear test conditions were an inlet oil temperature of 320 K (116 F), an outlet oil temperature of 350 K (170 F), a maximum Hertz stress of 1.71 GPa (248 ksi), and a speed of 10 000 rpm. Bench rolling-element fatigue tests were conducted at ambient temperatures with a bar speed of 12 500 rpm and a maximum Hertz stress of 4.83 GPa (700 ksi). The VIM-VAR M50NiL gears had a surface fatigue life that was 4.5 and 11.5 times that for VIM-VAR and VAR AISI 9310 gears, respectively. The surface fatigue life of the VIM-VAR M50NiL rolling-contact bars was 13.2 and 21.6 times that for the VIM-VAR and VAR AISI 9310, respectively. The VIM-VAR m50NiL material was shown to have good resistance to fracture through a fatigue spall and to have fatigue life far superior to that of both VIM-VAR and VAR AISI 9310 gears and rolling-contact bars

Thermomechanical Working of Electroslag Melted M-50 Bearing Steel ( Book )
1 edition published in 1972 in English and held by 1 WorldCat member library worldwide
A number of electroslag (ESR) melting procedures were investigated with the objective of establishing the thermomechanical working (ausforming) characteristics of M-50 bearing steel produced by this method. The ESR processes evaluated were: Electroslag remelted - Air melted electrode, Electroslag remelted - Vacuum induction melted electrode, Powder-strip electroslag melting, Double electroslag remelted - Vacuum induction melted electrode, and Continuous electroslag melting. Rolling contact fatigue testing, heat treat studies and other metallurgical tests were performed on most of these materials utilizing standard heat treat procedures as well as a thermo-mechanical process. In the latter case, high energy rate foward extrusion using Controlled Energy Flow Forming (CEFF) equipment was employed. Test results showed the ESR M-50 hardened by standard heat treat procedures to have comparable rolling contact fatigue lives to vacuum melted M-50. It was further indicated that ESR M-50 has improved workability over vacuum melted material in the ausforming temperature range. Thermo-mechanical processing however appeared to have little or no effect in improving the rolling contact fatigue life of ESR M-50. This is believed to be due mainly to the massive residual eutectic carbides observed in all of the ESR materials. This condition appears to be more severe and prevalent in the ESR M-50 than in material produced by vacuum melting. (Author)
Axial-Centrifugal Compressor Program, Evaluation of Ausformed Bearings ( Book )
1 edition published in 1976 in English and held by 1 WorldCat member library worldwide
A development program was performed to manufacture, test, and evaluate 35mm diameter ball bearings, using thermomechanically processed rings and balls. The program was subdivided into three main elements: manufacture of test bearings, test facility design and construction, and bearing life testing. All three tasks were completed successfully and are detailed in this report. 35-mm-bore angular contact ball bearings, typical of those used in advanced Army propulsion systems were produced using high-energy-rate forging techniques to form the inner and outer rings, and forward extrusion to produce the ball stock. These bearings were tested in specially designed turbine-driven high-speed test facility, at a speed of 65,000 rpm, at an axial load of 500 lb. and at a temperature of 160F-180F. The initial bearing configuration planned for this test series was found to be inadequate for the above test conditions. A series of iterations was therefore introduced which resulted in a viable test bearing

Fatigue Life of 120-mm Bore Ball Bearings at 600 deg F with Fluorocarbon, Polyphenyl Ether, and Synthetic Paraffinic Base Lubricants ( )
1 edition published in 1968 in English and held by 1 WorldCat member library worldwide
Groups of 120-mm bore angular-contact ball bearings made from AISI M- 50 steel were fatigue tested at a temperature of 600 deg F (588 K) and a speed of 12 000 rpm with a synthetic paraffinic oil, a fluorocarbon, and a 5P4E polyphenyl ether. Under a low oxygen environment, the synthetic paraffinic oil and the fluorocarbon gave bearing lives approximately 14 and 3 times AFBMA-predicted (catalog) life, respectively. With the poly-phenly ether, bearing life was less than AFBMA-predicted (catalog) life in an air environment. For the synthetic paraffinic oil and the fluorocarbon, bearing fatigue was subsurface initiated. For the polyphenyl ether, bearing failure was mainly from surface distress, wear, and superficial pitting
