Application of the Semenov theory of spontaneous ignition to evaluation of the critical temperature (Tc) in thermal explosion (TE) synthesis was conducted with the Ti-75at pct Al binary system using nonisothermal differential scanning calorimetry (DSC) at different heating rates. And the critical temperature for isothermal TE is predicted to be 728.9 by the multiple linear regression of Tcs evaluated according to Semenov theory, which is close to the range of 740~745 obtained from the isothermal DSC observation. This result proves that Semenov theory of spontaneous ignition is also feasible for TE synthesis in binary metallic systems like Ti-75 at. pct Al system.
