Formerly a student of NSIRC and Brunel University London, MSc in Structural Integrity, Mohammad Khairy will know be returning to NSIRC this March, after securing a PhD on the joining of stainless steel and nickel-based alloys with vacuum brazing process.
The research, supported by Brunel University London and sponsored by TWI, will investigate the effect of using hydrogen partial pressure in the vacuum brazing of stainless steels and nickel based alloys with metal based braze fillers. The investigation will involve microstructural analysis of different zones of the brazed joint using a variety of electron microscopes, leading to a deeper understanding of the interfaces in obtaining high performance of joints.
Mohammad completed his MSc in Structural Integrity at Brunel University London in 2018, where he developed his interest in the joining of nickel based alloys. His dissertation focused on an investigation of wire and arc additive manufacturing of nickel based alloys using novel wires.
Prior to his studies, Mohammed worked predominantly in construction and maintenance of power plants, and on oil pipelines as a welding engineer and inspector. He has acquired several qualifications throughout his career from internationally recognised organisations such as the International Institute of Welding (IIW), The Welding Institute, the British Institute of Non-Destructive Testing (BINDT) and the American Petroleum Institute (API).
Mohammed said: “I joined the Structural Integrity MSc course provided by Brunel University at NSIRC in 2017, which was a great opportunity to have an exposure to the cutting edge technology and to gain knowledge from industry experts. The research and industry environment I experienced at NSIRC during my dissertation, and the results I have managed to obtain, have encouraged me to conduct further research related to joining of nickel-based alloys”.
