Description

IN718 is a nickel-based superalloy composed of approximately 53 wt% Ni, 19 wt% Fe, 18 wt% Cr, 5 wt% Nb, and small amounts of Ti, Mo, Co, and Al. The alloy has a number of distinct phases present in its microstructure. These are namely the matrix, ?, and the precipitates, ?', ?'', and ?. The primary strengthening phase is ?'' [1], the composition of which is Ni3Nb. It has a body-centred tetragonal structure, and forms semi-coherently as disc-shaped platelets within the ? matrix, having three variants lying on the {100} planes. It is stable for over 10,000 hours at 600C; however, above this temperature it decomposes to form ?', Ni3Al (between 650C and 850C), and ?, the same composition as ?'' (between 750C and 1000C). It has been commented that, at large volum
