  • Diffusion during Powder Metallurgy Synthesis of Titanium Alloys
    Defect and Diffusion Forum, 2008
    Co-Authors: Orest M Ivasishin, V.I. Bondarchuk, D. Eylon, Dmitro G Savvakin
    Abstract:

    In the present study titanium alloys were synthesized by the blended elemental press-andsinter Powder Metallurgy approach using hydrogenated titanium Powder. Experimental investigation and modeling of the homogenization processes during synthesis were used to analyze peculiarities of mass transfer and factors affecting diffusion. Processes of alloying elements redistribution during chemical homogenization of Powder blends are shown to be strongly dependent on the chemical composition of the initial Powders. Optimization of the processing parameters allows to synthesize uniform, nearly-dense material with reduced grain size, at relatively low temperatures and short time. This will provide improvement of mechanical properties simultaneously with better cost-effectiveness of the process.

  • titanium Powder Metallurgy science technology and applications
    2015
    Co-Authors: Ma Qian, Francis H. Froes
    Abstract:

    Titanium Powder Metallurgy contains the most comprehensive and authoritative information for, and understanding of, all key issues of titanium Powder Metallurgy (Ti PM). It summarizes the past, reviews the present and discusses the future of the science and technology of Ti PM while providing the world titanium community with a unique and comprehensive book covering all important aspects of titanium Powder Metallurgy, including Powder production, Powder processing, green shape formation, consolidation, property evaluation, current industrial applications and future developments. It documents the fundamental understanding and technological developments achieved since 1937 and demonstrates why Powder Metallurgy now offers a cost-effective approach to the near net or net shape fabrication of titanium, titanium alloys and titanium metal matrix composites for a wide variety of industrial applications. * Provides a comprehensive and in-depth treatment of the science, technology and industrial practice of titanium Powder Metallurgy* Each chapter is delivered by the most knowledgeable expert on the topic, half from industry and half from academia, including several pioneers in the field, representing our current knowledge base of Ti PM. * Includes a critical review of the current key fundamental and technical issues of Ti PM.* Fills a critical knowledge gap in Powder metal science and engineering and in the manufacture of titanium metal and alloys

  • Titanium Powder Metallurgy
    Titanium Powder Metallurgy, 2015
    Co-Authors: Francis H. Froes
    Abstract:

    The history of titanium Powder Metallurgy (PM) is reviewed from the early days of the titanium industry (late 1940s) to the present day (late 2013). The first attempts at a PM approach to fabrication of solid titanium articles were displaced as a commercial process by ingot melting techniques. The blended elemental and prealloyed (PA)/hot isostatic press (HIP) approaches were investigated in the late 1960s and early 1970s with some success but no commercial applications. The status of titanium PM was comprehensively reviewed at a landmark TMS Conference in 1980. Around 1990, some early efforts at metal injection molding (MIM) of titanium with some nonstructural parts were made. This was followed by attempts at spray deposition of titanium in the 2000s and the development of commercial MIM (including structural components), blended elemental (a high point being the qualification of parts for Boeing commercial aircraft), PA/HIP, and additive manufactured technologies. A comprehensive review of titanium PM was documented at a conference in 2012.

  • The technologies of titanium Powder Metallurgy
    JOM, 2004
    Co-Authors: Francis H. Froes

  • MECHANICAL PROPERTIES OF METAL MATRIX COMPOSITES (Al/SiCp) PARTICLES PRODUCED BY Powder Metallurgy
    International Journal of Engineering Research and General Science, 2015
    Co-Authors: Bharath Venkatesh, B Harish
    Abstract:

    Metal matrix composites (MMCs) have become attractive for engineering structural applications due to their excellent specific strength property and are increasingly seen as alternative to the conventional materials particularly in the automotive, aerospace and defence industries. Al/SiC MMC has aluminium matrix and the silicon carbide particles as reinforcements and exhibits many desirable mechanical properties. In the present study, an attempt has been made to fabricate Al/SiC composite by Powder Metallurgy route as it homogenously distributes the reinforcement in the matrix with no interfacial chemical reaction and high localized residual porosity. SiC particles containing different weight fractions (10 and 15 wt. %) and mesh size (300 and 400) is used as reinforcement. The paper presents the processing of Al/SiC by Powder Metallurgy method to achieve desired properties and also the results of an experimental investigation on the mechanical properties of Al/SiC are determined.
