Microstructural Modeling During Multi-Pass Rolling of a Nickel-Base Superalloy
Superalloys are metallic alloys used for high temperature applications such as encountered in the aircraft industry and where resistance to deformation is a primary requirement. Alloy 718 and waspaloy are few examples of Nickel-base superalloys that resist deformation at elevated temperatures and are therefore difficult to hot work. The major hotworking operations are forging, extrusion, and ro...
متن کاملthe effect of e-64 on the developmental competence of sheep cocs during in vitro maturation
in the present study, the effect of e-64 at different concentrations (0.5, 1, 5 and 10 µm) added to (1) the ivm medium on oocyte nuclear maturation and developmental competence of ovine oocytes, and (2) to the ivc medium on embryonic development of ovine embryos were investigated.
On APFIM of Grain Boundaries in a Nickel Base Superalloy
Experimental details of atom probe field ion microscopy (APFIM) of a Ni-16Cr-9Fe alloy are presented. In particular, studies concerning analysis of intergranular carbides and borides and segregation to grain boundaries are described. It was found that NiZ3B6 precipitates are very sensitive to preferential field evaporation, which necessitates optimization of the analysis conditions. In the FIM ...
متن کاملTransmission Electron Microscopy Sample Preparation of INCONEL 738 Nickel-Base Superalloy
Size, shape, volume fraction and distribution of embedded g/ phase in g phase has direct effect on strength of INCONEL alloy. Microstructure parameters of INCONEL phases are quantified from microstructure images using transmission electron microscopy (TEM). Different TEM sample preparation techniques were used to study INCONEL 738 alloy microstructure for transmission electron micros...
