The evolution of advance materials should be accompanied with successful manufacturing processes such as joining.  Dr. AlHazaa research concerns the joining technology of dissimilar materials relating the process of joining with the properties of materials.  Diffusion bonding, Transient Liquid Phase (TLP) bonding, Spark Plasma Sintering (SPS) are examples of the processes used.  The research activity is extended to the areas of micro and nano joining by Femtosecond laser.  Coatings and alloying by nanomaterials for various applications in energy and environment is another area of interest.
