Refractory metals are a class of metals that are extraordinarily resistant to heat and wear and have extremely high melting points. Reactive metals have a strong affinity for oxygen and nitrogen at elevated temperatures and are highly resistant to corrosion at low temperatures.

    , and mullite. Adding titanium, zirconium, or hafnium to standard silver-based braze alloys forms an activated alloy. By firing such an alloy onto ceramic surfaces at 800 to 1,000 C in vacuum or argon, the braze will wet directly onto the ceramic through migration of the active metal toward the ceramic

    and another wire alloyed with 5% rhenium. Nozzle throats of forged and machined unalloyed tungsten have been used in solid-fuel rocket engines; at one time, throats were machined from porous consolidations of tungsten powder that were infiltrated with silver for exposure to gases at temperatures near
  • Resistance Welding Fundamentals (.pdf)
    , depending on physical characteristics, are used to. In general there are two categories of metals to be welded: produce fusion bonds. The bonded materials usually exhibit excellent tensile, peel. "Conductive" (such as aluminum, copper, silver and gold),. and shear strengths. and "Resistive" (steel

Resisting corrosion: A problem with magnesium has been its lack of sufficient corrosion resistance for many applications
  • Physics of Heat Processing
    as conduction. This ability to transfer heat within an object is called thermal conductivity. It varies for different materials. Gold, silver and copper have high thermal conductivity. These materials are also good conductors of electricity. Other materials, such as glass and mineral wool, have low
  • Stronger and Lighter -- Composites Make Their Mark
    greater fracture toughness than monolithic tungsten carbide, which is a brittle ceramic. Tungsten-carbide particlereinforced silver has been used for commercial circuit-breaker contact pads for many years. Ferrous alloys reinforced with titanium-carbide particles, marketed under the trade name

    the metal. In all other respects, GTA welding of titanium is similar to that of stainless steel. Normally, a sound weld appears bright silver with no discoloration on the surface or along the heat-affected zone. Want to use this article? Click here for options!. (C) 2011 Penton Media Inc. Email
