PROFESSIONAL EXPERIENCE

Graduate student researcher and Engineer Analyst

Maetta science inc., Varenne (Québec) and University of Québec (ÉTS), Montréal, Québec

Developed experimental tools to measure the impact of powder lots on properties of titanium, cobalt-chrome, 17-4PH, and superalloys mixture developed for powder injection molding (MIM)

Optimized moldability and reduced the adhesion problems in metallic injection molds

Characterized and developed the feedstocks (mixture) of metallic powder such as Cobalt-Chrome, titanium (Ti 6-4), steel (17-4 PH) for low-pressure powder injection molding (LPIM)

Experienced in the heat treatment of titanium and superalloys

Analyzed powder characteristics, solid loading, binder composition, temperature and shear rate to improve the feedstock viscosity

Worked actively with investigation team and laboratories such as NDT laboratories, Control laboratories (functional checks), metallurgical, chemical, and mechanical laboratories to investigate and identify problems arising to jet engine nacelle components

Performed metallurgical tests (SEM, EDX, electrical and metallurgical analysis) based on a thorough understanding of the problem

Prepared and presented concise technical reports Tools/Technologies: MCR 302 rotation rheometer, DSC PerkinElmer Pyris (differential scanning calorimetry analysis), TGA, Metal Injection Molding Machine, Stereo Microscopy, SEM/EDX, metallurgical analysis, metallography, microhardness testing, injection machine, root cause analysis, knowledge of wear mechanism, low and high cycle fatigue, fracture mechanics, and fracture surface analysis

Achievement: Increased 20% the moldability by optimizing temperature gradient between die and injection steps which is resulted in the selection of the best powders mixture candidate, and decreased material adhesion into the mold surfaces by modifying surface roughness with applications in metal injection molding (LP-MIM) Mar. 2017
