Abstract The isothermal section of the Nb-W-Zr system at 1373K has been successfully measured by means of electron probe microanalysis(EPMA) on diffusion couples. This isothermal section includes two single-phase regions, "$\alpha$" and (W,Nb)2Zr, and one two-phase region "$\alpha$" + (W,Nb)2Zr. The maximum solid solubility of Nb in (W,Nb)2Zr is 12.23at.% Nb.

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.
