  • Tensile Testing of Basalt Fibers Using a T-150 (.pdf)
    Basalt is a naturally occurring volcanic glass that has a nominal Young's modulus of 89 GPa.1 In the work described here, an Agilent T150 universal testing machine (UTM) was used to measure the Young's modulus and fracture strength of two types of basalt fi ber: one without binder and one
  • Caring for Cables
    a carrier material. Metal carriers have higher tensile strength than plastic and hold up better under heavy fill weights. Metal carriers also withstand high temperatures. Plastic, in turn, weighs much less than metal. This cuts the amount of power needed to move the carrier and may eliminate complex
  • Mitigation of Stress Corrosion Cracking in Nuclear Weldments Using Low Plasticity Burnishing (.pdf)
    (PWR) and boiling water reactors (BWR). SCC is understood to be the result of a combination of susceptible material, exposure to a corrosive environment, and tensile stress above a threshold. Tensile residual stresses developed by prior machining and welding can accelerate SCC. A surface treatment
  • Ferrous P/M
    parts from just about any metal, the most commonly used metals are the iron-based alloys. Low-density iron P/M parts (5.6 to 6.0 gm/cm >=), with a typical tensile strength of 16,000 psi, are usually used in bearing applications. Copper is commonly added to improve both strength and bearing properties
  • Products in the news at Hannover Fair
    . High-tensile synthetic fibers transmit forces as pure tensile loads. The wires have low thermal expansion, are chemical resistant, lubrication-free, and exhibit almost no wear. The modular units snap together and function similar to a ball joint. The power source for the robot arms is at the base
  • Powder-metallurgy awards of distinction
    . The sprocket is made from a modified MPIF FL-4405 PM material to a density of 7.4 gm/cm with an apparent hardness of 45 HR . And its tensile strength exceeds 200 kpsi. The sprockets are carbo-nitrided for tooth-wear resistance. Judges handed out two Lawn & Garden/Off-Highway awards of distinction. Geneva, Ill
  • The Friction Welding Advantage
    and upset of each weld performed - Fig. 3. Destructive testing, including bend, torsional and tensile tests, are performed, as well as nondestructive examination, to ensure the repeatability of the machines. Nondestructive examination can include ultrasonic, magnetic or X-ray inspections- Fig. 4
  • Tolerancing helical springs
    designer, tolerancing of helical springs is probably the trickiest part of the job and the most common issue with customers. One reason: The metal wire from which springs are formed can have widely varying mechanical properties between batches, especially tensile strength. Operators making
