An additive of Zr in the stiochiometric Ni_3Al, even slightly enriched Al, may be tough-ened and improved fairly on brittleness at 400--600℃. This behaves much better if Zr addedtogether with B. However, the high temperature ductility of Ni_3Al alloy containing Cr may besignificantly increased by Zr, which is slightly segregated along grain boundary. Thus, thetoughening mechanism by Zr seems to be different from that by B.
