ERZEUGNIS AUS EINER HOCHWARMFESTEN EUTEKTISCHEN VERBUNDLEGIERUNG SOWIE VERFAHREN ZU SEINER HERSTELLUNG

摘要

The directionally solidified heat resistant fibre reinforced composite consists of a Ni-super alloy matrix strengthened by ductile fibres of an alpha phase of Mo solid soln. base and located parallel to each other, these Mo fibres being substituted by a corrosion resistant Laves phase Mo(Ni1-xSix)2 near the surface of the alloy. The method is simple for improving the corrosion resistance of the composite. For high temp. applications, for example, for blades of gas turbines.
