    Thermal conductivity of printing material

    I am looking at an additive manufacturing route as an alternative to an existing technology which currently uses machined aluminium for its tooling. The process is thermally cyclic between 65C and room temperature and requires a good level of dimensional accuracy. While the mechanical properties...

    Grey and Ductile Irons

    @Maui, Thanks, I think I might have to track down a library with a copy as you've said, the price for a physical copy is so steep! Also, Thank you to everyone who has posted in the thread, it has been a big help.

    Grey and Ductile Irons

    Thanks Arunmrao, I'll have a look. but unfortunately I don't live in the states so attending lectures will be a bit tough Hi Swall, this isn't work related at the moment, but I would like to have the knowledge available if there does come a time when I am working with ferrous material. Steel is...

    Working out the stream flow radius for 100% liquidus alloys

    Bit of a weird one, and I thought this is the best place to ask as it is under "fluid mechanics". Just as a note, Fluid mechanic related math goes way over my head so please keep the explanations simple(ish). I need to work out an approximate inlet radius of a 100% liquidus metal flow when...

    At what point does a short freezing range alloy become a long freezing range alloy?

    Hello All, I have a large number of alloys with a number of base materials (aluminium, copper and nickel mostly) in a table listing the Liquidus, Solidus, Latent Heat, Feeding Effectivity and Solidification Morphology, stating if the alloy has a short or long freezing range. At first, I thought...
