  • Tensile Residual Stress Fields Produced In Austenitic Alloy Weldments (.pdf)
    Residual stresses developed by prior machining and. welding may either accelerate or retard stress corrosion. cracking (SCC), in austenitic alloys, depending upon. their magnitude and sign. A combined x-ray diffraction. (XRD) and mechanical technique was used to. determine the axial and hoop
  • Promising Future for New, Implantable Titanium Alloys
    Biomedical applications have long utilized austenitic stainless steels, titanium alloys and cobalt-chrome-molybdenum alloys for their excellent mechanical properties and sufficient biocompatibility and corrosion resistance. However, long-term biomed implants have demonstrated that these materials
  • Iron-Based Superalloys
    that are austenitic and are strengthened by a sequence of hot and cold working (usually, forging at 2,000 to 2,100 F followed by finishing at 1,200 to 1,600 F), and austenitic alloys strengthened by precipitation hardening. Some metallurgists consider the last group only as superalloys, the others
  • Unique Qualities of Stainless Steel PH15-7MO
    as compared to the Austenitic (300 series) or Martensitic (400 series) grades of stainless steel. Austenitic grades cannot be heat treated after fabrication, and the Martensitic grades, although heat treatable, do not make terrific retaining rings. From a purely visual perspective, it is not proper
  • Stainless Steel
    One of the features that characterize stainless steels is a minimum 10.5% chromium content as the principal alloying element. Four major categories of wrought stainless steel, based on metallurgical structure, are austenitic, ferritic, martensitic, and precipitation hardening. Cast stainless-steel
  • Determination of Volume Percent Retained Austenite by X-Ray Diffraction (.pdf)
    Hardening of steels requires heating to an austenitic phase and quenching to room temperature to produce a hard martensitic phase. Austenite is an FCC phase that is stable above a temperature of 735 C. Due to incomplete transformation some austenite is retained at room temperature. Retained
  • Examining the corrosion resistance of chromium-passivated stainless-steel tubes
    by reaction with adsorbed moisture on the wetted surfaces. CrP layers can be grown on both austenitic and ferritic stainless-steel surfaces. The formation of the CrP layer on a ferritic material is relatively easier than on an austenitic material because the former application requires fewer processing
  • Fatigue Performance of Nitinol Round Wire with Varying Cold Work Reductions (.pdf)
    cold work in five percent increments. These samples were subsequently heat treated, cut into test sections at room temperature, and subjected to strain-controlled fatigue testing in a temperature-controlled RO water bath at a constant 10 _C above the measured active austenitic finish temperature (Af).
