The laboratory is also equipped with NDE systems: (i) Multi-frequency range digital airscan ultrasonic instrument, SONDA 007 CX, complete with a pair of AS400A/HR airscan transducers, a motion control and data acquisition workstation, a 24-in x 24-in bench top lab scanning gantry and other related accessories. The system allows measurements in time domain for detection of damage and measurement in attenuation domain to characterize the defect and to analyze the interfaces for possible damage growth and (ii) The EchoTherm system, manufactured by Thermal Wave Imaging, Inc., Ferndale, MI. The system uses a pulse echo thermal wave and captures 3-D images in real time. A complete EcoTherm system with the UT crack detection module includes PC, flash lamps, hood, hi quality Infra-Red camera, all other hardware and software. The laboratory has many FBG interrogation equipments from Micron Optics including (i) si425-500 - provides fast (250Hz) interrogation of up to 100 sensors via Ethernet to a LabVIEW interface, (ii) sm125-500 - provides full-spectrum analysis at 1Hz, and (iii) standard polyimide-coated splice-free FBG arrays. The Integrated Mechanical Testing Laboratory: Servohydraulic and screw driven computer controlled Instron and MTS load frames, with low and high cycle fatigue capabilities. High temperature testing can be conducted in air or inert atmosphere up to 1000 C. A new testing setup is being acquired to test at temperatures up to 1800 C in either vacuum or inert atmosphere. This setup will be operational in the summer of 2006. Ultrasonic equipment for elastic constant measurement and damage characterization is available. A CamScan Series 4 scanning electron microscope is also available. This microscope can be used with an electromechanical micro-tensile deformation stage for in-situ testing. A maximum load of 4,400 N can be applied with a maximum travel of 25 mm. This stage can be driven from outside the microscope, which allows monitoring the deformation as it occurs. The microscope is in the process of being upgraded with a EDAX-TSL Orientation Imaging Microscopy (OIM) dedicated system. This system will count with the OIM 3D add-on, to characterize microstructure in 3-D and also to analyze changes in microstructure and local orientation as a function of load during in-situ testing.

ASU Center for High Resolution Electron Microscopy (CHREM): JEOL-2000FX TEM with 0.28 nm point-to-point resolution, light-element sensitive X-ray detectors and PEELS. Other TEMs, such as a Philips CM20, and a Topcon 0028 can be used for conventional diffraction work. In addition, the CHREM also counts with a FEI XL30 Field Emission Environmental SEM. This microscope has a resolution of 2 nm while operating under vacuum at 30 kV and 5 nm resolution under high vacuum at 1 kV. This microscope counts with an Orientation Imaging Microscopy (OIM) system from TSL, Inc. This system allows the collection of spatial distribution of local crystallographic orientations with a resolution that can be as good as 0.05m thanks to the field emission gun. Crystallographic texture, distribution of grain sizes and grain boundary misorientations can be obtained easily as a byproduct of this measurement. This microscope can also accept the 4,400 N micro-tensile stage to perform tests in-situ. The CHREM also has several conventional SEM’s that can be used for imaging, X-ray analysis with a beryllium window, and backscattered electron imaging. All these capabilities will be used, as required, for characterization of the samples before and after deformation. In addition, a high precision Focused Ion Beam (FIB) is available. This FIB has both ion and electron columns for SEM imaging of micromachining operations, which makes it simple to perform serial sectioning around defects. This piece of equipment can also be used to deposit or machine rectangular grids on the surface of the samples to improve DIC measurements and to prepare TEM specimens of particular locations.

Fatigue and Crystal Growth Lab: P. Peralta also counts with laboratory space that will be used for this project. This laboratory has a fume hood, where etching and electropolishing can be carried out using available chemicals and power supplies and an electro-discharge machining (EDM) unit to facilitate sample preparation. This lab also counts with a Centorr tri-arc furnace, which can be used to prepare alloys via arc-melting for preliminary testing or as raw material for optical floating zone processing. The furnace can also be used to prepare directionally solidified alloys and single crystals.

Scanning Probe Microscopy Lab: several scanning probe microscopes, able to work in STM or AFM mode, and two profilometers, can be used to characterize the surface morphology around points of interests, including defects and cracks. In addition, a large format AFM, a DI-3100, is available to map the surface topography of large deformed samples, as an additional step to quantify damage. A Hysitron Triboindentertm setup can be used for nanoindentation to determine mechanical properties at particular locations of interest in the microstructure, including grain boundaries and other defects.

Materials Evaluation Laboratory

The Laser-Based Materials Evaluation Laboratory under the direction of Prof. Spicer has a 400 ft2 laboratory facility designed for laser ultrasonic characterization of materials microstructure. Equipment includes a Nd:YAG pulsed laser (8 ns, 200 mJ,1064 nm), a path-stabilized interferometer system using a diode-pumped YAG laser (532 nm), optical hardware for optical probe isolation and an optical vibration isolation table (4 ft x 8 ft). Additional ultrasonic detection equipment includes a Fabry-Perot interferometer, various EMAT receivers, piezoelectric pulser-receivers including contacting piezoelectric probes. Furnaces with controlled atmosphere are available for characterization studies at elevated temperatures.

Additional equipment in this facility includes an ultrafast (100 fs) laser system for thin films materials diagnostics and characterization as well as a pulsed laser deposition system (PLD). The PLD system has the capability of processing materials using near IR (1064 nm), visible (532 nm) and UV wavelengths.

Additional facilities are available through The Johns Hopkins University Advanced Technology Laboratory and include additional ultrasonic evaluation equipment. For laser ultrasound, these include the following: a Continuum pulsed laser (4-7 ns pulse duration) operating at 1064 nm wavelength, beam steering mirrors, lenses, optical fiber for beam delivery, a Burleigh Fabry- Perot interferometer, a Michelson interferometer, a diode pumped YAG laser for interferometry (Coherent Verdi), lenses, mirrors, optical fibers for beam delivery and collection. For air-coupled detection, equipment includes capacitive air-coupled detectors with charge amplifiers (MicroAcoustic Instruments). Other equipment includes scanning acoustic microscopes and ultrasonic c-scan systems.

Materials and Spectroscopy Laboratory (MSL)

Access to the Materials and Spectroscopy Laboratory (MSL) at the Johns Hopkins Applied Physics Laboratory is also available to support the proposed program. This laboratory is set up to provide a center for making optical measurements in support of component testing, system design, and system evaluation. Specific efforts address development of technology and systems for high-speed optical guidance, development of remote sensing techniques, seeker system performance testing, biomedical measurements, optical signal processing experiments, and development of mensuration equipment. The laboratory is equipped with general-purpose and special-purpose equipment for making standard optical measurements, for environmental and experiment control, for data acquisition, and for measurement evaluation.

The laser ultrasonic facility at MSL also provides the capability of measuring microstructural and macrostructural properties of ceramics and metals at elevated temperatures. Ultrasonic wave generation is accomplished using either a pulsed Nd:YAG or CO2 laser, depending on the optical absorption properties of the material under investigation. Detection of the ultrasonic wave arrivals is accomplished using either a stabilized Michelson-type in interferometer or a stabilized Fabry-Perot interferometer. Each of these interferometers uses a Coherent 150 mW frequency-doubled Nd:YAG laser as a source. Sample heating can be accomplished using one of two high-temperature tube furnaces. These furnaces can reach temperatures of 1700C, which is critical for evaluation of high-temperature window materials.


Metallurgical sample preparation facilities for grinding, polishing and etching materials for microstructural characterization are available. SEM with EDS, TEM, and XRD equipment are available as shared departmental facilities.
