15 صفحه اولThe Effect of High Temperature Exposure on Dendritic Segregation in a Conventionally Cast Ni Based Superalloy
Dendritic segregation in conventionally cast, commercially heat treated and exposed MarM002 turbine blades has been investigated using scanning electron microscopy (SEM) and energy dispersive X-ray analysis (EDS). During casting Cr, Co and W segregate to the dendrites and Hf, Ti and Ta segregate to the eutectics. As a result of the dissolution of γ' precipitates in the dendrites and coarsening ...
