Softening of nickel in the vicinity of its Curie point Academic Article uri icon

abstract

  • The dynamic yield strength of commercially pure nickel (99.5% Ni), as determined by planar impact experiments, shows a fivefold decrease in the close (±50°C) vicinity of its Curie point. The effect is attributed to the enhanced adsorption of impurity atoms by stacking fault ribbons (Suzuki atmosphere) that takes place in a narrow temperature interval.
