Spring 2018 Update: ME – Databases

New versions of ME-Databases (ME-Al1.1, ME-Fe1.2, ME-Ni1.2) are now available.  The major updates are given below.

ME-Al1.1.

• Assessment of metastable Si-phase, forming building subunits of Mg₅Si₆ (β’’) strengthening phase,
• Assessment of Al-solubility in MgSi co-cluster phase
• Improvement of L12-type strengthening phase Al3(Sc,Zr) phase stability reproduction.
• Improvement of solidi and liquidi representation in Al-Sc-Zr system.
• Improvement of solidi and liquidi representation in AA7xxx alloys.

ME-Fe1.2

• Reassessment of metastable epsilon-carbide phase.
• Reassessment of Sigma-phase stability and composition.
• Reassessment of austenite/ferrite relative phase fractions in high-alloyed stainless steels.

ME-Ni1.2

• Reassessment of ϒ’-phase compositions (in particular the Al/Ti ratios).
• Reassessment of element partitions between ϒ (matrix) and ϒ’ phases (in particular the partition of W).
• Reassessment of μ- and M₆C- phase stabilities in high Cr-Mo-W alloyed supperalloys of René type.
