Phase diagram of the Co–Al–W system. structure and phase transformations near the Co3(Al, W) intermetallic composition range

详细

Low-temperature portion of the polythermal section for the Co–Al–W system in the vicinity of the Co₃(Al, W) intermetallic composition has been studied experimentally using electron microscopy and hightemperature X-ray diffraction analysis. Low-temperature structural phase transformations and temperature ranges of the existence of phases have been determined. The morphology of Co₃(Al, W) intermetallic particles was studied as a function of the tungsten content in alloys.
