<p>A nickel base superalloy composition for castings, subjected to hot isostatic pressing and subsequent heat treatment is described. The alloy consists of:
Fe 15 to 24 wt %
Cr 10 to 15 wt %
Mo 0 to 3,3 wt %
Nb + Ta 5,25 to 6,5 wt %
Ti 0,65 to 2,25 wt %
W 0 to 6,5 wt %
Al 0,2 to 0,8 wt %
Ni + Co balance
Articles having the invention composition have properties which are significantly better than similarly processed IN7l8 articles. </p> |
