Test Methods and Properties of Materials


  1. 1.

    Stress-rupture tests were carried out on reinforced specimens of composite materials consisting of an alloyed matrix and tungsten or molybdenum fibers at temperatures of 900 and 950°C.

  2. 2.

    A technique is proposed for studying the character of rupture of composite materials, consisting in dissolving the specimen matrix after testing and grading the fiber fragments by length. The most frequently encountered fiber-fragment length is approximately equal to the critical length.

  3. 3.

    The character of rupture of composite materials in long-time tests at elevated temperatures is examined.

  4. 4.

    On the basis of a metallographic analysis of the interfacial zone in the composite materials tested, it is concluded that a stable reinforced materials could be produced by using mutually saturated components.
