Effect of boron doping on environmental embrittlement of Ni3(Al, Mn)
Description
In intrinsically brittle polycrystalline Ni3Al alloy, boron ductilizes the intermetallic, meanwhile eliminating the harmful effects of a moisture-containing environment. Macroalloying with manganese makes Ni3Al inherently ductile. Whether boron addition can further ductilize this alloy and eliminate environmental effects in this case has not yet been determined, although this is very important as regards the elucidation of the mechanism of boron eliminating embrittleness (both intrinsic and extrinsic) of Ni3Al-based alloys. In this paper, the authors investigate the effect of boron doping on environmental susceptibility of Ni3(Al, Mn), giving additional evidence that boron doping is capable of eliminating environmental embrittlement in Ni3Al-based intermetallics
