Auf der Suche nach neuen Materialien haben Forscher der TU Hamburg eine weitreichende Entdeckung gemacht: Ihnen gelang der Nachweis, dass die Steifigkeit kristalliner Metalllegierungen in dem von der Natur vorgegebenen Zustand am höchsten ist. Anders gesagt: Es gibt auf diesem Sektor nichts, was besser ist als die Natur. Mit diesem Ergebnis wird die weltweite Suche nach neuen steifen Materialien zumindest auf dem Gebiet der kristallinen Metalllegierungen in Frage gestellt. Die am Institut für Keramische Hochleistungswerkstoffe gewonnenen Erkenntnisse sind in der heute erscheinenden Ausgabe der Fachzeitschrift "nature" Gegenstand eines vierseitigen Berichts.
