Abstract:
Turbo machinery components such as blade integrated disks (BLISKs) and
nozzle guide vanes (NGVs) made from Nickel and Titanium base alloys such
as Inconel 718, Ti-6Al-4V, Ti-6246, Ti-17, Mar-M247 and CMSX-4 are
predestinated for repair and salvage operations due to their high value.
Currently these components are manufactured by time and cost intensive
process chains containing processing steps such as casting, forging,
milling, linear friction welding, thermal spraying etc.
The laser additive manufacturing process Laser Metal Deposition (LMD)
offers new effective entire process chains by decreasing the number of
processing steps as well as by enabling emerging applications for
specific process steps. Parts can be repaired which were formally
classified as non-repairable and components can be manufactured
additively by new process chain designs and new processes.
This talk addresses the pathways from feasibility studies over process
developments yielding in certified processes and industrially
implemented machines. For BLISK manufacturing the single blades are
directly manufactured additively on the disk by LMD. The significant
increase of the deposition rate combined with a near-net-shape
deposition is realized by the use of up to 10 kW laser power and the
first application of a newly-designed LMD head with an integrated
zoom-optics. The achievable metallurgical, mechanical - static and
dynamic mechanical properties - and geometrical results, the implemented
process chains including CAD/CAM/NC-coupling are presented and
discussed.

TRDA workshop on financing tech startups
Tuesday, October 26, 2010
LightPath Technologies is sponsoring a Laser Focus World Webcast on IR Optics: Meaningful Specifications for Complex Aspheres
Increasingly, aspheric optical elements are moving from the specialized to the commonplace. Nowhere is this more pronounced than in IR optical systems, where it is common to find more aspheric elements than spherical ones. But despite the increasing use of aspheres, specifying their shape and other properties is still far from a routine process.
Greg Forbes of QED Technologies will present a new and intuitive way to mathematically represent rotationally symmetric aspheric surfaces, leading to easier interpretations and sanity checks as well as more-direct assessments of manufacturability. Dave Aikens of Savvy Optics will highlight some of the key issues to consider when specifying an aspheric optical element, and will provide guidance on making the best use of the optical-drawing formats available to the user today.
- Review of conventional asphere-shape representation
- A new, simpler way to represent aspheres
- Review of surface-form tolerancing
- Key issues in specifying an aspheric optical element
- Guidance on specifying for manufacturability
Who Should Attend:
Engineers, Optical Designers, Optical System Engineers, Optical Manufacturers, IR System Designers.

Spin Transfer and Nonlinear Magnetization Dynamics in Ferromagnetic Nanostructures
Spin transfer torque from a spin-polarized current applied to a metallic ferromagnet can excite magnetization oscillations of very large amplitude. We use this unique property of spin current to study new types of magnetization dynamics in the strongly nonlinear regime.
I will describe our recent measurements of spin-current-driven dynamics in nanoscale ferromagnetic dots and ferromagnetic nanowires. In these systems, we observe several unusual magneto-dynamic phenomena that include non-adiabatic stochastic resonance, rapid current-induced domain wall motion and size quantization of nonlinear magnon scattering. I will also briefly discuss emerging technologies such as universal magnetic memory and microwave nanooscillators that utilize interactions between spin currents and magnetization in nanoscale magnetic tunnel junctions.
OPEN SOURCE: Is Open Really Free
Title: OPEN SOURCE: Is Open Really Free
Presenter: Howard Gitten with Edwards Angell Palmer & Dodge LLP
Date: Wednesday, November 3rd, 2010
Time: 9:30-11:00
Location: University Tower Building located at 12201 Research Parkway,
2nd Floor large conference room #211, Orlando, FL., 32826
Fee: $20 (Free to only UCF Incubator clients and Florida Photonics Cluster members)
RSVP to Renee Ayala at 407-882-0202 or via email rayala@mail.ucf.edu
Many companies from Incubator start ups to Microsoft are increasingly making use of Open Source
software. But what does that really mean? We will explore what is meant by 'open source', some
of the more common licenses, and what business ramifications it may have for downstream use,
investors, and joint development partners.

UCF Physics: Nobel Laureate Dr. David M. Lee's Talk on Nov 4, 2010

Nobel Laureate Dr. David M. Lee from Texas A&M University will present a
talk on'The Magic of Superfluids' onThursday, November 4, 2010 at 4:20
p.m. in Classroom Bldg 1, Room 121.
About David M. Lee: He graduated from Harvard University in 1952. He
obtained a Masters degree from the University of Connecticut. In 1955
Lee entered the Ph.D. program at Yale University where he worked under
Henry A. Fairbank in the low-temperature physics group, doing
experimental research on liquid3He . After graduating from Yale in
1959, Lee took a job at Cornell University, where he was responsible for
setting up the new Laboratory of Atomic and Solid State Physics.
Together with Robert C. Richardson and their graduate student at
Cornell, Doug Osheroff, David M. Lee was awarded the Nobel Prize in 1996
for the discovery of superfluidity in 3He, and the identification of its
phase diagram.
