Metallurgical Evaluation

Dirats Laboratories is an authority on microstructures, with expertise in phase formation and characterization that extends to coating materials, advanced processing systems and all alloy systems-superalloys, stainless steels, nickel and cobalt alloys, electronic and commercial alloys. Digital Metallographic Imaging
The metallographic lab evaluates specimens of thousands of materials using light and scanning electron microscopy and image analysis. Master digital images are stored on CDs and retained indefinitely with original quality and resolution.

METALLURGICAL EVALUATION-LATEST NEWS

Kodak 460 Digital Cameras
By replacing conventional photography with digital imaging, Dirats has set the stage for electronic manipulation, analysis, archival or transmittal of micro and macro photographs. The high resolution images measure 3060 x 2036 pixels; file sizes are 6 MB in monochrome and 18 MB in 12-bit color. This resolution allows clear examination of metallographic details without the fuzziness or pixelation of lower quality digital images.

Jeol JSM-5900LV Scanning Electron Microscope
This advanced instrument is fully PC-driven without analog controls. Its features include built-in automation, data storage and dual vacuum operation-high vac for standard samples and low vac for nonconductive samples. Even more versatility is provided by its Energy Dispersive Spectrometry (EDS), which adds chemical analysis and phase chemical mapping capabilities.
