Microstructure of titanium

  1. May 26, 2012 #1
    hey, everyone,

    i am really confused about microstructure of titanium,one is deformed and one is original both of them is 20x, have a look at the image attachment,

    i know that the grey scratched is twinning and slip marks due to deformation, what about those white parts and black parts?

    thank you....

    Is this Cp-Ti (commercial purity) or another alloy like Ti-6Al-4V?
    I'm guessing it is Cp-Ti because the first picture looks like equiaxed grains of alpha-phase.

    The second image looks like widmanstatten phases. Was there a heat treatment on the alloy?
    Check out this book on Titanium. It has a few good micrographs you can compare with:

    hi streeters,

    thanks for helping, but this section is done,

    the lecture said that...it was relatively pure titanium, the reason why lighter/darker region is due to its own orientation.

    i feel it was not very good explaination, but it fits her marking scheme so m gonna settle with that.
