    Better process for tool set loading before hot pressing?

    Thank you both for your information so far. I'd like to answer the previous three questions. 1) We do both ceramic and metal powders in elemental form as well as alloyed. Most of the time, we press one elment of metal powder. It is usually raw powder from a mine that is spherical in shape and...

    Better process for tool set loading before hot pressing?

    Hello, I work in a laboratory and we are experimenting with hot pressing raw powder (ceramics, metals, etc). Due to the nature of hot pressing and the expense of the powder, it is necessary for us to press near net shape. To do this, we load the powder into a graphite die ring in the shape of...

    Need Help With Off Center Axial Loading Calculations Please

    Hello, I am using a hot press machine to press powder into a designated shape. The force comes from above the powder and is axial only. The powder is placed in a circular die and another "punch" is placed between the die and the actual pressing ram. I am trying to prove the implications of not...

    Oxygen reducing atmosphere for Ruthenium ?

    Does anyone have any suggestions for a reducing atmosphere for Ruthenium that won't cause a new Ruthenium phase? This atmosphere would occur in hot isostatic pressing (HIP) and/or hot axial pressing. I'm not sure if an atmosphere like hydrogen or carbon monoxide(dioxide?) would do the trick...

    How to calculate thermal conductivity for a Silver alloy?

    Hello, I need to calculate the thermal conductivity of a Silver alloy but am unsure about how to do it. The primary element in the alloy is silver at approximately 98% wt%. The rest of the alloy is comprised of 4 other elements. Is there a way to calculate the K-value of this entire alloy...
