Conclusions

  1. 1.

    A formula is proposed for calculating the critical self-ignition temperature of a porous metal plate in an exothermic oxidation reaction obeying a parabolic law.

     
  2. 2.

    Experiments with Zr, Hf, and Ti specimens carried out with the aim of verifying the critical selfignition temperature formula yielded values showing good agreement with calculated T0 values.
