    Formula for efficiency improvement

    Is there a setup time that varies when you combine these parts? If so, this needs to be taken into account. Otherwise this sounds like the old economics guns vs. butter argument. If you know this classic example, the idea is that a society can produce x amount of guns or y amount of butter...

    TI-6-4 heat treatment to minimize grain size

    A few areas of it are nearly 1/2 in (125mm) thick, but the thickness through most of it is about .170 in (43mm). The application regularly cycles the part in the 150 - 250°F (65-120°C) range and doesn't really have significant pressures or aggressive materials on it, but is cleaned quite...

    TI-6-4 heat treatment to minimize grain size

    Thanks for your help. I am now looking to find the NPL report coolkid referenced. Also, the lower 1024 C temp sounds like a more typical number as I dig into this further, plus the quench to below 250 is a noteworthy addition mentioned by TVP. The notes I have indicate an even steeper quench...

    TI-6-4 heat treatment to minimize grain size

    I am looking for the optimum heat treatment to make a more homogenous part for an investment cast Ti-6-4 machining blank. My ultimate goal is to make it more machineable for a fine surface finish (<10RMS). What I have so far is that I think the cycle should be a solution treatment above the...
