Latest Patents

Jean-Marc Lang holds a patent for a process aimed at obtaining crystals of intermetallic compounds. The invention relates to a method for producing isolated monocrystals by cooling alloys in their molten state. This process involves using an alloy composition that allows the first phase to crystallize during solidification to correspond to the desired compound. The method includes slow cooling through cyclic stirring and thermal cycling, avoiding the temperature at which another solid phase appears, followed by the abrupt expulsion of the residual liquid. This technique is particularly useful for obtaining large monophase primary crystals of compounds that melt congruently or incongruently, including those with symmetry of order 5, known as 'quasi-crystals'.
