 Abstract

The thesis aim to study the brazing using transient liquid phase technique (TLP) traditional and two steps to join Ni-based super alloys types (IN738LC, IN939) then comparing between similar IN738LC, Similar IN939 and dissimilar IN738LC/IN939. The connection done using 70um foil of BNi-2 filler in vacuum environment. A successful joining efficiency and homogenous microstructure for all types 

  After the discussion, the committee recorded its notes on the thesis, which were split between explanation and correction, and the student’s defense of his work and the discussion ended. The committee decided to evaluate the thesis and grant the student a science master’s degree in materials engineering with a full grade.
