Fabrication of Dense Nickel Aluminide Monolithic and Composite Bodies By Combined Self Propagating High Temperature Synthesis and in Situ Containerless Hot Isostatic Pressing
Keyword(s):
ABSTRACTMonolithic Ni 3Al and composite Ni3Al/ceramic whisker bodies were fabricated by combined Self Propagating High Temperature Synthesis and in situ containerless Hot Isostatic Pressing (SHS/HIP), starting from cold pressed blends of nickel, aluminum, and boron powders, with and without additions of alumina whiskers. The resultant bodies were dense and had good ductility and mechanical strength at room temperature.
