    Fractography of Debris Question Re Deflagration vs Detonation

    As the header suggests, I'm looking for some literature for my research/investigation that can help differentiate the appearance of debris from a Deflagration vs Detonation perspective. There are many aspects of the investigation I cannot talk about based on contracts/ legal constraints, so I...

    De-oxidation of Magnesium Blocks

    Gentlemen, I work at an Aluminum casting facility. Often we add large blocks of pure Mg (between 250 and 1k lbs). Some of these have been quarantined due to excessive surface oxidation. We have procedures for cleaning the surface mechanically, but it is very time consuming and we have an...

    Faster Wet-Chem analysis of Silicon in Aluminum alloys

    I recently changed jobs to an Aluminum casting facility. We typically use OES for our material composition tests, but in certain situations we perform a wet-chemistry method of detection (typically for the major alloying elements). We would like to do this for Silicon, due to the higher...

    High Silicon Steel Decarb

    I am an intern at a company that melts and rolls many different grades of non-stainless steel. We have had some consistent issues with de-carb in some high-silicon steels (particularly 1% or higher Si). The grades we melted with this issue also typically have .40% + carbon. Do high Si steels...
