The plasticity of alloy ÉI 929

  • V. K. Adamovich
Heat-Resistant Steels and Alloys


  1. 1.

    The elongation vs temperature curves for the ÉI 929 alloy at strain rates of 3.6–3.7×106 %/h show a sharp reduction of deformation capacity due to damage in the grain boundaries.

  2. 2.

    At the low point on the elongation vs temperature curves the grain size has no noticeable effect on intergranular damage or plasticity.

  3. 3.

    In the temperature-time region 50–100°C above the low point on the elongation vs temperature curves the number of grain boundaries with cracks increases and the plasticity decreases with increasing grain size.
