Effect of heat treatment upon the microstructure and hardness of a wrought cobalt-base alloy stellite 21 (AMS 5385)

Description: Report presenting an investigation of the response of wrought Stellite 21, a typical cobalt-base alloy, to heat treatment. The alloy was solution-treated and transformed by aging and isothermal transformation at temperatures of 1200 to 1950 degrees Fahrenheit for periods of 5 minutes to 72 hours. Results regarding the solution-treated structure, precipitation by isothermal transformation, precipitation by aging, grain boundary behavior, and hardness are provided.

Relation of microstructure to high-temperature properties of a wrought cobalt-base alloy Stellite 21 (AMS 5385)

Description: Report presenting an investigation to determine the effects of microstructure on the stress-rupture life of heat-treated wrought Stellite 21 under stress and temperature conditions comparable to those encountered during engine operation of turbine blades and to correlate with other microstructure properties. Results regarding the stress-rupture life, elongation, hardness, metallographic examination, and room-temperature tensile tests are provided.

Further Studies of the Mechanism by Which Hydrogen Enters Metals During Chemical and Electrochemical Processing

Description: Note presenting studies of the entry of hydrogen into metals from chemical and electrochemical action, which occurs when hydrogen-metal alloy formation is simultaneous with discharge (or release) of hydrogen atoms. Results of some new experimental investigations and some correlations with other studies are provided.

A Further Investigation of the Effect of Surface Finish on Fatigue Properties at Elevated Temperatures

Description: Note presenting an investigation to evaluate the effects of surface roughness on fatigue properties of low-carbon N-155 alloy with a grain size of ASTM 6 and of S-816 alloy with a grain size of ASTM 6 to 7. Fatigue studies were conducted at 80, 1200, 1350, and 1500 degrees Fahrenheit. Results regarding those fatigue tests and the surface investigation are provided.

Friction and wear investigation of molybdenum disulfide 2: effects of contaminants and method of application

Description: Report presenting a study using a low-speed kinetic-friction apparatus to show the effects of method of application and contaminants on the lubricating characteristics of molybdenum disulfide MoS2. Friction coefficients for the purified grade can vary from 0.025 to 0.12 just by changing the method of application.
