Abstract
A mode of grain boundary precipitation in Fe-37.3wt%Ni-3.58wt.%Ti-02wt.%C alloy aged at 823K has been investigated by transmission electron microscopy. Fine γ' particles of L12-type ordering firstly precipitated within the γ matrix during ageing treatment at 823K. The aged matrix phases (γ and γ') were later encroached on by the grain boundary lamellar phases. Quite uniquely, these duplex fine lamellae are composed of alternately aligned ferrite and γ' platelets. These two phase constituents in the lamellae are separated by the interrace arallel to both {110}γ, and {111}γ' planes.
