DESCRIPTION:Title: <a href="https://researchseminars.org/talk/MathMAC/35/"
 >Multiwell model of phase separation: Arbitrarily strong total-spreading c
 ase</a>\nby Karel Tůma as part of Modelling of materials - theory\, model
  reduction and efficient numerical methods (UNCE MathMAC)\n\n\nAbstract\nI
 n this work\, we revisit a multi-well phase separation model in the contex
 t of β–ω transformations in titanium alloys. We propose a new formulat
 ion by modifying the algebraic structure of the interfacial free energy. T
 his adjustment relaxes the standard coercivity constraint on surface tensi
 ons in total-spreading regimes and\, importantly\, prevents the formation 
 of mixed ω–ω states—configurations that are crystallographically imp
 ossible. We demonstrate the effectiveness of the proposed model through si
 mplified simulations and outline a path toward more realistic three-dimens
 ional modeling of β–ω phase transitions in titanium alloys.\n
