• Iterative Taguchi Analysis: Optimizing The Austenite Content And Hardness In 52100 Steel (.pdf)
  ,. quenching and perhaps cryogenic cooling procedures. two thermal treatments were noted each producing. must be determined. hardness of 58-59 HRC in combination with zero. retained austenite as measured by x-ray diffraction. This paper describes an application of a Taguchi. analysis to reach an optimal...
• Aluminum
  spectrum, is nonsparking, and nonmagnetic. A four-digit number that corresponds to a specific alloying element combination usually designates wrought aluminum alloys. This number is followed by a temper designation that identifies thermal and mechanical treatments. To develop strength, heat-treatable...
• Determination of Volume Percent Retained Austenite by X-Ray Diffraction (.pdf)
  . failure analysis including the measurement of. fatigue striation spacing, critical crack size,. Austenite can transform in service as a result of. cleavage fracture, ductile fracture, intergranular. thermal cycles, plastic deformation, or shock. Shot peening, for example, will transform the. fracture...
• Thermography Applications in Technology Research
  of the. heat treatment of large crankshafts, test and measurement of thermal barrier coatings, analysis of the hole-. drilling residual stress measuring technique, the thermal spraying of protective coatings, measurement and. evaluation of hot-air soldering of joints on electronic circuit boards...
• Carbon Steel
  by chemical composition, mechanical properties, method of deoxidation, or thermal treatment (and the resulting microstructure). Wrought steels are most often specified by composition. No single element controls the characteristics of a steel; rather, the combined effects of several elements influence...
• Nanostructured Steels Are On The Horizon
  times better than copper wire with twice the thermal conductivity of diamond. THE BEGINNINGS OF NANOSCALE STEELS. In recent years nontraditional nanoscale "steels" have also made head way. The first advances have revolutionized the field of hard magnets. These high-energy-density permanent magnets...
• Properties of 17-4 PH Stainless Steel Produced via Press and Sinter Route
  ). In the present study efforts were made to determine the mechanical properties achievable with the press. and sinter PM process, when the thermal history and carbon contents are kept within well defined ranges. Properties were determined in the as-sintered, as-solution annealed, and after aging...
• Alloy Steel
  , however, the term alloy steel is reserved for those steels that contain a modest amount of alloying elements and that usually depend on thermal treatment to develop specific properties. With proper heat treatment, for example, tensile strength of certain alloy steels can be raised from about 55,000...
