    The Physics Of Collision
    When we drive our vehicles down the road, we are driving them at a certain velocity and direction. All vehicles have weight and mass to the order of a few hundred pounds for a motorcycle, a few thousand pounds for a large SUV or luxury car or several tons for a tractor-trailer truck. When our vehicles move at speed down the road, they create energy by virtue of their mass and forward velocity

    Failure Analysis of Ball Bearings
    The four seized bearings submitted for metallurgical analysis were determined to have suffered deterioration of their grease to the point that it was inhibiting motion rather than enabling. The grease had turned to a thick (viscous) black sludge that was full of particulate. Electrical pitting was found in the seized bearings, especially the inner races. Signs of axial (thrust) loads were noted, mainly in the outer raceways. Larger arc strike regions were found on the balls.

    Stress Corrosion Cracking And Intergranular Corrosion of a 316Ti Stainless Steel Preheater Tube
    A cracked 316Ti stainless steel preheater tube was analyzed to determine the failure mechanism. A second non-cracked tube section from a different elevation was also analyzed to determine the condition of the tube material.

    Analysis Of An Impact Fractured, Welded Steeting Arm Spindle Assembly
    A welded left front spindle/steering arm assembly that had fractured at the fillet weld joint between the steering arm and inner brake boss was received for analysis to determine the mode of failure.

    6/6/2011 · Metallurgy
    Analysis Of Chloride And Mic Pitted Still Condenser Tubes
    Several concentrating still condenser tubes exhibiting pitting were received to determine the cause of pitting. Results indicate the tubes pitted initially from the inner diameter (ID) surface due to microbiological corrosion (MIC). MIC pitting initiated preferentially at the tube seam weld. Additional ID surface pits and significant pit enlargement of MIC pits due to chloride pitting were also observed. The chlorine is likely remains from the hydrochloric cleaning process
