application of PSO needs to be extended, hybrid with other algorithms is thought a good way to
improve APSO algorithm and applying the improved algorithm to complex problems is the goal of

Abstract: The microstructure and phase constitution of Mo(Si1- x, Alx)2 alloys (x = 0.03, 0.1
and 0.4) prepared by self-propagation high-temperature synthesis is first investigated using SEM,
EDS and XRD analysis. Then the lattice parameters and adiabatic temperature are calculated.
Based on the above experimental and calculated results, the variation mechanism of diffraction
peaks and phase transformation subsequence of the Mo-MoO3-Si-Al powders is discussed.
Results show that, when the self-propagation reaction is over, there are a homogeneous Mo-Si-Al
alloy melt and a fused Al2O3 with lower density at top. Subsequently, MoSi2 or Mo(Si, Al)2 phase
nucleates and grows as a primary phase in the Mo-Si-Al alloy melts, and then Al, Si substances
