Materials/Metallurgy Lab - US Technical Center

An essential part of the commercial grade dedication process is verification of material composition.

The materials and metallurgy lab uses advanced analysis methods to verify compliance with purchase specifications, and metallography to investigate material properties of manufactured components.

Our lab is supported by a full machine shop for sample preparation services. Custom welding services are also available.

Materials Analysis

  • ALLOY ANALYSIS (AES, LECO GDS500-A) – Glow discharge optical atomic emission spectrometry for quantitative materials analysis.
  • CARBON/SULFUR ANALYSIS (LECO CS230) – Inductively coupled combustion/infrared detection for PPM-level sensitivity with as little as one gram of material.
  • ALLOY SCREENING (XRF) – Non-destructive X-ray fluorescence allows quick identification of material alloy family (steel, aluminium, Inconel, Monel, Brass, Bronze) for sorting or high-level analysis.
  • FTIR – Analysis of non-metallic components using Fourier Transform Infrared spectroscopy.

Mechanical Testing

  • TENSILE/COMPRESSION – Up to 125,000 lbs.-force (yield, Ultimate, Elongation, and reduction of area).
  • HARDNESS – Rockwell B, C, Superficial N; Shore A, D
  • MIRCO-HARDNESS – Knoops & Vickers Methods

Metallography

  • MOUNTING – Hot-press or cold set mounts for metallographic preparation depending on specimen and analysis to be performed.
  • GRAIN STRUCTURE AND SIZE – Physical comparison or computer measurements
  • SURFACE EXAMINATION – Investigation of welds and microstructure
  • SCANNING ELECTRON MICROSCOPE/EDS – The SEM can acquire images for general imaging of morphology from ~30x to well over 100,000x. The SEM is equipped with two accessories, an Energy Dispersive Spectrometer (EDS) and an electron backscattered diffraction system. The EDS system can identify the elemental composition of material. The composition can often be quantified to weight percent. The elemental information can be displayed in a large number of formats including graphical spectra, quantitative line scans, elemental distribution mapping, Excel tables for concentrations, etc. The EDS software also can also perform “feature analysis” to count and quantify porosity, sizes and compositions of inclusions in material, etc. Back-scattered electron images can also be employed to produce images with contrast based on variations in atomic number across a surface.

Corrosion Testing

  • STATIC AUTOCLAVES – Three 1-gallon static autoclaves allow short-term evaluation of corrosion and material investigations at primary coolant conditions, up to 1500 PSIG and 750°F.
  • DYNAMIC AUTOCLAVES – Ideal for longer term investigations of corrosion performance and material performance issues at reactor operating conditions.
