MATERIALS LABORATORY CASE STUDY 5 THE PROBLEM A filter was removed from a stator cooling system after pressure differential sensors indicated it may be blocked. The filter was submitted to SI’s Materials Laboratory for analysis to help identify the material blocking it. Figure 1. The filter shown in the as-received condition Figure 2. The yellow […]

MATERIALS LABORATORY CASE STUDY 3 THE PROBLEM Structural Integrity received several sections of core reinforcing steel from a client performing work at a local university gymnasium (Figure 1). SI’s client needs to have an understanding of the material tensile strength in order to obtain the appropriate replacement material. THE SOLUTION Cross-sections were removed from each […]

MATERIALS LABORATORY CASE STUDY 1 THE PROBLEM A small metallic particle that had contaminated a product line was brought to SI’s Materials Laboratory for analysis.  The goal of the analysis was to identify the particle’s composition to help identify its original source. THE SOLUTION The particle was examined and documented in a scanning electron microscope […]
