This book was released on 1977 with total page 13 pages. Available in PDF, EPUB and Kindle. Book excerpt: Some titanium alloys have the advantage of possessing the capability of hardening to high strength levels through the thickness of heavy sections. Such an alloy is the metastable beta titanium alloy Ti-8Mo-8V-2Fe-3Al (Ti-8823). This study is concerned with the tensile property variation exhibited by Ti-8823 after its fabrication and heat treatment in heavy section. Information on the tensile behavior was obtained from tension specimens taken from three through-the-thickness locations; outside diameter, midwall, and inside diameter. Values for the following parameters were obtained at each location: yield strength (0.1 and 0.2 percent offset), tensile strength, reduction in area, elongation, and modulus of elasticity. From these data, the variation (standard deviation) for each parameter was determined. Variations in tensile properties as well as hardness measurements of Ti-8823 were compared to those experienced with heavy-section steel gun tube forgings and another titanium alloy in heavy section, namely the alpha/beta Ti-6Al-6V-2Sn alloy.

This book was released on 1973 with total page 36 pages. Available in PDF, EPUB and Kindle. Book excerpt: Appreciable strength levels were retained to 650 C in a Ti-10Al-1Si alloy aged in the (alpha alpha sub 2) phase field to yield optimum room temperature strength and ductility. The aging treatment precipitated a uniform distribution of alpha sub 2-particles such that, at room temperature, dislocations bypassed instead of shearing the particles at low strains. Specimens fractured at room temperature exhibited fine uniform dimples even for those aging conditions that imparted no macroscopic ductility. The main crack appeared to propagate through the planar slip bands that had cut through the alpha sub 2-particles. A two-step aging process produced a higher volume fraction of bimodally distributed alpha sub 2-particles that led to higher strength levels at elevated temperatures. Both for the single size and the bimodal alpha sub 2-particle distributions, elevated-temperature deformation structures consisted mainly of planar slip bands that sheared through the alpha sub 2-particles.

This book was released on 2018 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The residual stress distribution introduced by shot peening (SP) in the deformed surface layer of Ti-6Al-4V and (TiB+TiC)/Ti-6Al-4V were simulated and studied via the three-dimensional (3D) finite element dynamic analysis and the experimental validation. The program of ANSYS/LS-DYNA was utilized, and the 3D homogeneous and inhomogeneous models were set up. The homogeneous model was established for simulating SP process on Ti-6Al-4V. The influence of three important parameters, the shot balls' size, shot velocity and coverage rate on residual stress distribution were investigated. Numerical simulation results showed that these parameters contributed different effects on SP treatment. Using a simplified method, an inhomogeneous model for simulating SP process on (TiB+TiC)/Ti-6Al-4V was set up. The max tensile and compressive residual stress (CRS) was +1155 and −1511 MPa, respectively. Based on this stress distribution, the beneficial effect of reinforcements was indicated during deformation, retarding the damage to the matrix and keeping the adverse tensile stresses in the reinforcements. In order to verify the results of simulation, the residual stress distribution along depth was measured by X-ray diffraction (XRD) method. The residual stress distribution by experiments was agreed with the simulated results, which verified the availability of 3D finite element dynamic analysis.

Available in PDF, EPUB and Kindle. Book excerpt: Progress is reviewed for a research program which is examining selected processing-microstructure-property relationships which limit the mechanical properties of P/M Ti alloys in particular and aspects of ductile fracture in general. The approach is quite broad and ranges from experimental and analytical studies of the effect of porosity on the fracture of engineering alloys to be an experimental examination of the hot isostatic pressing of metallic powders. Progress for the period 10/1/82-9/30/83 is reviewed for the following aspects of this research program: the tensile deformation and fracture of alloys containing porosity; experiment and modeling of P/M titanium alloys; the influence of strain-rate on the flow and fracture behavior of titanium and nickel containing porosity; a modeling study of the influence of void distributions on the mechanism of ductile fracture; hot isostatic pressing of metallic powders; and the influence of plastic anisotropy on the hydrogen embrittlement of titanium under multiaxial states of stress.

This book was released on 1974 with total page 19 pages. Available in PDF, EPUB and Kindle. Book excerpt: The tensile behavior, erosion/impact resistance, mechanical fatigue strength, thermal fatigue behavior, and creep strength of filamentary reinforced aluminum and titanium alloy matrix composites were briefly compared. Parallel to the filament direction, aluminum matrix composites are slightly stronger than titanium matrix composites up to a temperature of about 600°F (314°C). Titanium matrix composites, however, have shown significant off-axis strength advantage even at room temperature. B/SiC-Ti has shown a five-fold advantage in transverse strength over B-A1 at a test temperature of 500°F (260°C). The erosion rate of fiber-reinforced composites was found to be controlled by the matrix until the filaments became exposed. The titanium matrix, having an order-of-magnitude stronger matrix yield strength, exhibited greatly improved ballistic impact resistance, when compared to the aluminum matrix system. The low-cycle fatigue strength of titanium composite was superior to that of comparable aluminum composite. On the other hand the high-cycle fatigue strength in the 0 deg orientation for the titanium composite was significantly lower than that of a comparable aluminum composite. The resistance to thermal fatigue damage, when measured by tensile strength degradation, delamination, and dimensional distortion, was in favor of titanium composites. The transverse creep strength of B/SiC at 800°F (427°C) was shown to be ten times better than that of B/SiC-A1 at 575°F (302°C).

Download or read book Residual Stresses in Friction Stir Welding written by Nilesh Kulkarni and published by Butterworth-Heinemann. This book was released on 2013-11-20 with total page 59 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book describes the fundamentals of residual stresses in friction stir welding and reviews the data reported for various materials. Residual stresses produced during manufacturing processes lead to distortion of structures. It is critical to understand and mitigate residual stresses. From the onset of friction stir welding, claims have been made about the lower magnitude of residual stresses. The lower residual stresses are partly due to lower peak temperature and shorter time at temperature during friction stir welding. A review of residual stresses that result from the friction stir process and strategies to mitigate it have been presented. Friction stir welding can be combined with additional in-situ and ex-situ manufacturing steps to lower the final residual stresses. Modeling of residual stresses highlights the relationship between clamping constraint and development of distortion. For many applications, management of residual stresses can be critical for qualification of component/structure. - Reviews magnitude of residual stresses in various metals and alloys - Discusses mitigation strategies for residual stresses during friction stir welding - Covers fundamental origin of residual stresses and distortion
