"Science is facts; just as houses
are made of
stones, so is
science made of
facts; but
a pile of stones
is not a house
and a collection
of facts is not necessarily
science."

Research Equipment/Facilities

Our laboratory (Advanced Materials Laboratory or AML) is located in McClure 422. The lab is equipped with a simultaneous thermal analyzer, Lindberg high temperature furnaces, High Temperature Vacuum Furnace (up to 2000 degree C), Buehler Isomet 1000 cutting machine, high energy ball milling equipment (SPEX Mill 8000M), SPEX-2380 bench press, an inert atmosphere glove box, TEM sample preparation kit (Gatan Disc Punch, Fischione Disc Grinder and Twin-Jet Polisher), and a full metallography facility including an Allied HighTech TwinPrep Grinder/Polisher.

     

The AML is equipped with three mechanical test instruments: A Lever Arm (20:1) ATS 2335 Creep Tester that can perform tensile creep testing up to 1000 degree C in air; A universal tester (Instron 5982) primarily for performing room temperature and high temperature tensile tests (funded by a NE-UP Infrastructure Grant) at different temperatures and strain rates; and a Vickers microhardness tester (LECO LM100).

The Department of Chemical and Materials Engineering houses a fully equipped machine-shop at the Buchanan Engineering Laboratory (BEL) on-campus. The Center for Electron Microscopy and Microanalysis, a University of Idaho facility, has a LEO Supra 35VP field-emission-gun scanning electron microscope (FEG-SEM), one AMRAY 1830 SEM, a JEOL transmission electron microscope (TEM) and a Siemens D5000 X-ray diffraction equipment are located in the McClure Hall and easily accessible.

Dr. Charit's group also utilizes the state-of-the-art analytical instruments available at the Center for Advanced Energy Studies (CAES) at Idaho Falls. These include a High Resolution TEM, SEMs with Focused Ion Beam (FIB) and Electron Backscatter Diffraction (EBSD) capabilities and Local Electrode Atom Probe (LEAP). These instruments can provide valuable information on the intrinsic structure of materials at a very fine level. These instruments are used either as part of the funded ATR-NSUF users facility projects or at a charge. A former PhD student (Somayeh) has used these instruments as part of her dissertation work. Furthermore, the spark plasma sintering machine present at the Advanced Materials Lab at CAES in collaboration with Prof. Darryl Butt, Boise State University.

A pressure resistance welding (PRW) machine was purchased from the Centerline Ltd. using an AFCI grant in the past. Currently, the machine is located at the Instrumentation Shop at the CAES, Idaho Falls. Dr. Charit's group has been successful in joining a variety of high temperature metallic materials (MA956, MA957, HT-9, tungsten) using the PRW technique.
