美国桑迪亚国家实验室材料科学、冶金或机械工程博士后招聘

Job Description

This postdoctoral position is a temporary position for up to one year, which may be renewed at Sandia's discretion up to five additional years. The PhD must have been conferred within five years prior to employment. Individuals in postdoctoral positions may bid on regular Sandia positions as internal candidates, and in some cases may be converted to regular career positions during their term if warranted by ongoing operational needs, continuing availability of funds, and satisfactory job performance. : **Are you passionate about your work and dream of utilizing state-of-the-art facilities to explore solutions? Do you want to join a dynamic team that solves significant issues for our nation’s security?** We are seeking a mechanical engineer, civil engineer, metallurgical engineer, materials scientist or similar who has recently earned their Ph.D. to collaborate with a diverse community of senior researchers engaged in developing a comprehensive understanding of fatigue, fracture and failure of structural materials, such as steel and aluminum alloys and their welds. This scope includes how fracture and damage processes in materials change upon exposure to environments such as hydrogen, hydrogen isotopes, sub-ambient temperature and moisture. On any given day, you may be called on to: + Design and execute mechanical experiments to probe environment-deformation interactions as well as fatigue and fracture processes in complex microstructures in metal alloys + Develop experimental platforms and test plans to study specific aspects of microstructural evolution and performance during deformation, including manufacturing processes + Use principles of both physical and mechanical metallurgy to develop understanding of the materials, their microstructures and their deformation and fracture behavior + Perform microstructural assessment and characterization using electron microscopy tools, individually and in collaboration with staff + Communicate your findings to colleagues, customers and the larger scientific community through presentations, technical reports and articles suitable for publication in high-impact journals

Required:

You have the following: + A PhD in materials science, metallurgical or mechanical engineering, or a related field + Experience with fatigue and/or fracture of metals and metal alloys + Experience with servohydraulic mechanical test frames for tensile, fracture, and fatigue testing + A record of first-author or co-authored scientific publications in the above areas within peer-reviewed journals and presentations at scientific conferences + Ability to obtain a Department of Energy Q-level security clearance

Desired:

You also have one, or more, of the following: + Documented experience with microstructural characterization of structural steels and/or aluminum alloys using conventional and advanced microscopy and microanalysis techniques + Strong understanding of physical and mechanical metallurgy and knowledge of thermomechanical processing of steels and aluminum alloys + Familiarity with the effects of hydrogen on the behavior of structural materials: ferritic and austenitic steels and aluminum alloys + Experience with light sources and neutron diffraction to evaluate residual stress and microstructure + Design of experiments (including safety planning) + Collaborative work habits – ability to efficiently leverage available expertise + Inclusive research approach - ability to work with a diverse group of scientists and engineers + Excellent communication skills

Department Description:

The Hydrogen and Materials Science (8367) team provides expertise to both Sandia and the Nation on the interaction of hydrogen (and its isotopes) with all types of materials. The Department performs scientific and engineering research to develop fundamental understanding on the aging of materials in gaseous environments, including hydrogen, and applies this understanding to determine its effects on the performance and reliability of materials relevant to Sandia’s nuclear weapons and energy missions. Department staff conducts research and development primarily for two important customers: 1) Gas Transfer Systems (GTS) for the Nation's Nuclear Weapons Enterprise; and 2) the Fuel Cell Technologies Office (FCTO), part of DOE's Office of Energy Efficiency and Renewable Energy. The Department’s work covers a broad range of areas, including analyzing hydrogen’s long-term impact on materials used in fuel cell and gas transfer systems, developing solar thermochemical technology for hydrogen production, assessing the suitability of materials for hydrogen storage, advising hydrogen safety codes and standards, maintaining and enhancing nationally recognized core and enabling capabilities in hydrogen science, and initiating hydrogen storage and fuel cell market transformation strategies to bring technological advancements towards broad-based commercial availability.

Security Clearance:

​Sandia is required by DOE to conduct a pre-employment drug test and background review that includes checks of personal references, credit, law enforcement records, and employment/education verifications. Applicants for employment need to be able to obtain and maintain a DOE Q-level security clearance, which requires U.S. citizenship. If you hold more than one citizenship (i.e., of the U.S. and another country), your ability to obtain a security clearance may be impacted. Applicants offered employment with Sandia are subject to a federal background investigation to meet the requirements for access to classified information or matter if the duties of the position require a DOE security clearance. Substance abuse or illegal drug use, falsification of information, criminal activity, serious misconduct or other indicators of untrustworthiness can cause a clearance to be denied or terminated by DOE, resulting in the inability to perform the duties assigned and subsequent termination of employment.
