PROFESSIONAL EXPERIENCE:

2004 – PRESENT: Research Assistant

Department of Chemical and Materials Engineering, University of Kentucky

Lexington, KY

• Developed and completed two research projects, funded by NSF and DoD respectively, on continuous cast 2xxx, 3xxx and 5xxx Al alloys.

• Researched the tensile and fatigue properties of the CC AA 2xxx Al alloys produced by conventional processing; designed an optimized thermo-mechanical processing to refine grain structure and obtain a maximum very fine precipitation, with which the fatigue properties were enhanced as high as 28%.

• Studied fatigue behavior of the 2xxx Al alloys produced by conventional and optimized methods, including fatigue limit testing, crack initiation and propagation and fracture mechanism investigation.

• Evaluated the strengthening mechanism of 2xxx Al alloys using material characterization techniques, such as SEM, TEM, EBSD and XRD.

• Investigated the relationship between texture, microstructure and mechanical properties in 3xxx and 5xxx Al alloys during hot rolling, cold rolling and recrystallization; developed a model to predict the evolution of textures and structures during such thermo-mechanical processing.

• Studied the formation mechanism of a detrimental recrystallization texture and designed a thermo-mechanical processing to minimize its volume fraction in 3xxx Al alloys, by which the formability and mechanical properties were markedly improved.

• Conducted thermo-mechanical experiments on Al alloys, including cold rolling, batch and salt bath heat treatment, quenching, stretching and natural and artificial aging.

• Performed comprehensive analysis and solution of failures of fan hubs made by cast Al alloys; developed Fracture mechanics study on Al alloys and steels.

• Skilled running lab equipment to develop investigation on mechanical properties (tension, fatigue, macro and micro hardness) and material characterization (SEM, EBSD, XRD, OM, EDS and TEM).

• Drafted and finalized NSF annual report; summarized and presented project development to peers on group meeting and annual materials conference.

• Explored the new function and drafted testing specification of existing tensile machine; made various samples for OM, SEM, TEM, EBSD, tension and fatigue experiments.

• Directed graduate students on metallographic experiments and mechanical tests; trained students on using of electronic microscopes, fatigue and tension equipment.

• Drafted and published over ten technical articles in prestigious materials journals the referred conference proceedings so far.

1998 – 2004: Materials Research Engineer

Beijing International Aeronautical Materials Corporation, Beijing, China

• Initiated, managed, and conducted projects on the metallurgy of superalloys; Studied roles of critical elements on the casting, diffusion behaviors, microstructure stability, strengthening, and high temperature performance of the superalloys.

• Investigated the boundary condition between module shell and the melted superalloy; developed phase identification of various materials, including ceramic, composite, metallic alloys and coating; determined the crystallographic orientation of single crystal superalloy; measured residual stress and retained austenite of various steels.

• Managed a metallographic laboratory with various material analytical testing and technical services; provided technical support to other departments and customers; Assisted in resolving metallurgical problems to all aspects of gas turbine manufacturing processes.

• Published eight technical articles in materials journals.
