I am looking for the SFE of different grades of each metallic alloy; meaning I wish to find separate values for AL 7075-T6, AL 6061, AL 2024, etc for instance. Does anyone know of sources/articles that present such database?
Thanks
Dear Arash
Refer to the following website:
(https://en.wikipedia.org/wiki/Stacking-fault_energy)
There is no single report that collected SFE of all metals in one article. Non-ferrous metals are totally different from ferrous metals. C-steels are different from stainless steel. You should survey the SFE of a certain metal. There are some equations originally used to predict the SFE of a wide range of stainless steels. Most of the non-ferrous metals (Al-based alloys & Ti-based alloys) have a high SFE of order > 100 mJ/m2.
Thanks everyone for the answers. I have done a survey over the internet for a few of the alloys that i had in mind and no luck so far except for SS 304 and SS 316. Like I implied, there is plenty of resources that mention the SFE for pure form metals ( Al, Cu, Ti,…), but nothing that particularly differentiates between different grades of a particular metal; F.E. Al 7075, Al 6061, Al 2024, Al 1350 , etc .
Yes it is true.In crystallography, a stacking fault is a planar defect that can occur in crystalline materials. Crystalline materials form repeating patterns of layers of atoms. Errors can occur in the sequence of these layers and are known as stacking faults. The stacking-fault energy (SFE) is a materials property on a very small scale. It is noted as YSFE in units of energy per area. A stacking fault is an interruption of the normal stacking sequence of atomic planes in a close-packed crystal structure. Then anyone can have a database of it for different metals.
