What is Determination of Lattice Parameter and Strain of Ï' Phases in Nickel-Base Superalloys by Synchrotron Radiation Parallel Beam Diffractometry about?
## Abstract The lattice parameters and strain of Υ'-phase particles in Nickel-base superalloys, which are duplex type alloys designed for turbine blades and widely called “Ni-base single crystal superalloys”; they are accurately determined by Synchrotron Radiation parallel-beam diffractometry. The superalloys have __Υ'__ precipitates, an ordered FCC structure based on Ni~3~Al, in a γ-matrix having disordered FCC structure. In addition, the preparation method of stress-free Υ'-phase particles, with no composition change in the preparation process, was newly developed to measure the coherency strain of Υ'-particles due to lattice misfit. The prepared Υ'-phase particles are similar in composition and form to Υ'-phase particles in the γ-matrices. The method for determining of the lattice misfit between the __γ__ and γ’ particles was previously reported.
