Description Researcher
Responsibilities:

Perform advanced Electron Microscopy procedures and other analytical techniques to provide and interpret results in support of research into products and processes for manufacturing rolled aluminum sheet materials. Investigate complex problems in aluminum manufacturing using electron microscopy, determine the appropriate techniques need to solve the problem, and conduct the necessary research in order to propose solutions. Specific responsibilities include:
• Optimizing Scanning Electron Microscopy (SEM) parameters to detect features, such as particle size, shape and chemistry and analyze the data to interpret how the material has been processed;
• Using SEM to identify and analyze defects in aluminum sheet products and use this information with prior knowledge to establish the origin of the defect in the process stream;
• Using SEM to measure oxide thickness in automotive aluminum alloys;
• Using Electron Back Scatter Diffraction to relate grain structure to processing routes and properties such as formability;
• Using SEM to analyze polymer coatings on aluminum beverage can surfaces;
• Using Dynamic Mechanical Analysis instrumentation to gather information on glass transition temperatures and strength of polymer coatings;
• Applying Dynamic Ultra Micro Hardness testing to aluminum sheet products;
• Using Electron Back Scattered Diffraction analysis for grain orientation (crystallographic texture) determination of automotive sheet products to enable improved process parameters to be recommended;
• Using SEM/EDXS to perform chemical analysis of intermetallic particles in aluminum sheet;
• Developing non-standard sample preparation techniques for Electron Microscopy such as use of ultramicrotomy for TEM analysis of the near surface disturbed layer, and oxide thickness measurements of rolled aluminum sheet products;
• Developing and improving electrochemical polishing protocols for feature detection and analysis of precipitates;
• Using a wide range of equipment and techniques for specimen preparation, including electropolishing and ultramicrotomy. Applying these techniques to the characterization and investigation of aluminum alloys and including both bulk and surface aspects;
• Evaluation of treatments and polymer coatings applied to the surfaces of aluminum products used in the manufacture of, e.g., beverage cans and automotive vehicles;
• Developing non-standard specimen preparation techniques and characterization methods tailored to individual investigations and designed to provide the specific information required;
• Working closely with other researchers to interpret the findings and apply them to the specific issue or question at hand;
• Conducting routine instrument maintenance and troubleshooting of equipment as well as overseeing service contracts and engineers for more complex maintenance and repairs;
• Prioritizing a high turnover of work requests, with good customer focus and communication to identify the specific needs of the requested investigations and clearly convey the results in both verbal and written forms;
• Identifying needs for new equipment and recommending new equipment options; and
• Training technologists and other researchers in the use and application of some of the equipment and techniques.

Qualifications
Qualifications:

Requires a Bachelor’s degree (or foreign equivalent)* in Electronic Microscopy, Electronic Engineering Technology, Materials Sciences, or a directly related field plus eight (8) years experience operating advanced electron microscopy and other equipment.
• Experience must include the following equipment and procedures:
o Scanning electron (SEM) and transmission electron (TEM) microscopes;
o Electron dispersive X-ray analysis (EDX) for microanalysis;
o Electron backscatter diffraction (EBSD) for determination of crystallographic orientations of grains and texture determination;
o Metallography and optical microscopy and Digital image processing and data basing.
• In-depth knowledge and experience of the operation and use of electron microscopes and other specialist equipment applied to the research of aluminum rolled products;
• Ability to take problems stated by others, propose solutions to address them, and solve the problem using ideas from self and others;
• Ability to organize, lead and report on microscopy examinations related to Novelis' key products (e.g., beverage can and automotive sheet);
• Experience in the development and application of specimen preparation techniques for microstructural characterization of aluminum alloys by SEM, TEM and optical microscopy;
• Experience in routine electron microscopy equipment maintenance and troubleshooting, and coordination of instrument service support;
• Knowledge and experience in the safe use of various hazardous materials and reagents, such as liquid nitrogen and chemicals for electropolishing and etching.
*Employer will accept a combination of education and experience as determined by a qualified evaluation service as equivalent to a Bachelor's degree.
