Notes:
MoSi2 is one of the few intermetallics to have potential for further systems. However, the use ofMoSi2 has been hindered due to the brittle nature of the material at low temperatures, inadequate creepresistance at high temperatures, accelerated (pest) oxidation at temperatures between 450~ 550°C. In thisinvestigation Mo(Al,Si2)/Ti3SiC2 composites has been prepared by reaction hot-pressing from Mo, Si,SiC, Ti, Al powder mixture under different temperatures. XRD results show that the main products areMo(Si,Al)2 and Ti3SiC2. Part of TiC and SiC also appeared at low treating temperature. With the treatingtemperature increasing SiC disappeared. No evidence show lattice change of Mo(Si,Al)2. It must be theresults of sufficient Al added. The electrical conductivity properties were also investigated. Samplestreating under different temperatures showed different changes. Samples under high treating temperatureshowed a near linear change ranging from 27~800°C and Samples under low treating temperature showeda nonlinear change
