Refinement of lamellar microstructures by boron incorporation in GE-TiAl alloys processed by Spark Plasma Sintering
JS Luo, T Voisin, JP Monchoux, A Couret - Intermetallics, 2013 - Elsevier
The aim of this study is to check the efficiency of boron in refining lamellar microstructures of
TiAl alloys densified by Spark Plasma Sintering. Boron-containing TiAl47Cr2Nb2B0. 6 and
boron-free TiAl47Cr2Nb2 alloys were consolidated at varying temperatures. Their
microstructures were studied by both scanning and transmission electron microscopies and
their tensile properties were measured at room temperature. The structures and chemical
composition of borides were analyzed. With the formation of borides, this addition of boron …
