Abstract Stacking fault energy and stacking fault nucleation energy are defined in terms of the physical nature of stacking faults and stacking fault energy, and the measuring basis for stacking fault energy. Large quantities of experimental results are processed with the aid of a computer and an expression for calculating stacking fault energy has been obtained as $\gamma$300SF(mJ·m-2)=$\gamma$0SF+1.59Ni-1.34Mn+0.06Mn2-1.75Cr+0.01Cr2+15.21Mo-5.59Si-60.69(C+1.2N)1/2 + 26.27(C+1.2N)(Cr+Mn+Mo)1/2+0.61[Ni·(Cr+Mn)]1/2.

Altmetric calculates a score based on the online attention an article receives. Each coloured thread in the circle represents a different type of online attention. The number in the centre is the Altmetric score. Social media and mainstream news media are the main sources that calculate the score. Reference managers such as Mendeley are also tracked but do not contribute to the score. Older articles often score higher because they have had more time to get noticed. To account for this, Altmetric has included the context data for other articles of a similar age.
