Study on Combustion Behavior of TC4 and Ti40 Alloys
OM,XRD,SEM,EDS were used to test.and analyze the combustion products of TC4 and Ti40 alloys by layer-by-layer from reaction frontier to matrix The result shows that: titanium alloy can be divided into 4 sections,combustion surface(CS),molten zone(MZ),transitional zone(TZ) and influence zone(IZ).The CS is mainly consist of TiO2,and with oxide of V.Cr2O3 and SiO2 are detected on CS of Ti40.MZ of TC4 is in loose and porous state.There are lots of cracks and holes in the TZ and IZ; MZ of Ti40 is compact,between MZ and IZ there is a TZ which is rich of V and Cr,it can stop oxygen diffusing effectively.From the MZ to matrix,oxygen content reduces gradually,and oxide of Ti with different valence state is detected.Because of effect of oxygen,the hardness of the two alloy increase after combustion,increment of Ti40 is much greater than that of TC4.
