Is there a way to determine when the rod first starts to crack without doing a destructive test? I know that mfgenggear suggested using a penetrant dye but I would rather not do this method due to the high volume of test samples. I'm bending the threaded rod and I would like to stop applying...
I am going to perform a test in which I will be bending various steel rods. Some of the rods will be exposed to conditions that make them much more brittle than others, and the test will consist of bending the straightened rods until the first signs of crack initiation. Comparison between the...
I found a good deal on an olympus GX 41 with an attached Paxcam and software (http://www.olympus-ims.com/en/microscope/gx41/). Would this be a good starter unit for microstructural characterization?
What is the typical magnification required by a light microscope to view and analyze the various microstructures of steel? Does anyone recommend a good, cheap microscope with a digital hookup to a computer that I can purchase?
Thanks,

So if i'm ordering this material from a supplier, would it usually be normalized? If so, how would I call this out on a drawing? Let's say the machinist gets the drawing and he goes to order the material, at a minimum what information do I need to specify for him? Also, would you recommend a...
I would like to have a part machined from 1040 steel and I'm wondering if this material has a good machinability rating? Ideally I would like to have a tensile strength of at least 100 KSI for a 5" x 12" x 2.5" sheet, and I'm wondering how I would provide a material call out for this on the...
