: Transition metal nanoalloys of Ti-Co, Ti-Ni and Ti-Zn were prepared by hydrazine reduction of metal chloride in ethylene glycol at 60oC and characterized by X-ray diffraction (XRD) and Scanning electron microscopy (SEM). The average particle size for Ti-Co, Ti-Ni and Ti-Zn was measured to be 28.2, 16.1 and 24.6 respectively using X-ray diffraction pattern. The effect of bimetal nanoalloys (BMNs) on the thermal decomposition of ammonium perchlorate (AP) was investigated using
Thrmogravimetric analysis (TGA), Differential Scanning Calorimetric (DSC) studies. Activation energy of high temperature decomposition (HTD) of with different alloy nanoparticles was calculated using DSC by Kissinger equation. The catalytic
activity of nanoalloys is much sensitive to oxygen and may be effective to improve the decomposition efficiency of AP and AP based propellants.
