Journal ArticleDOI
Dynamic recrystallisation and precipitation behaviour of high strength and highly conducting Cu–Ag–Zr-alloys
F. Bittner,S. Yin,Alexander Kauffmann,Jens Freudenberger,H. Klauß,Grzegorz Korpala,Rudolf Kawalla,Rudolf Kawalla,W. Schillinger,Ludwig Schultz +9 more
TL;DR: In this article, the authors investigated the dynamic recrystallisation of CuAgZr alloys within a composition range of (3-7) and (0.05-0.3) Zr as a function of alloy composition, temperature and strain.
Journal ArticleDOI
Effect of biaxial cyclic severe deformation on structure and properties of Ti-Ni alloys
Victor Komarov,Victor Komarov,I. Khmelevskaya,Roman Karelin,Sergey Prokoshkin,M. Zaripova,Margarita Isaenkova,Grzegorz Korpala,Rudolf Kawalla +8 more
TL;DR: In this paper, a true nanocrystalline structure with grain/subgrain size of 50 nm has been formed in bulk equiatomic Ti-Ni samples for the first time.
Journal ArticleDOI
Thermodynamics of martensite formation in Fe–Mn–Al–Ni shape memory alloys
Alexander Walnsch,Mario J. Kriegel,Mykhaylo Motylenko,Grzegorz Korpala,Ulrich Prahl,Andreas Leineweber +5 more
TL;DR: In this article, it is shown by thermodynamic considerations that the undercooling of a shape memory alloys is caused by the resistance of the B2 precipitates to undergo the transformation to the L10 structure enforced by the martensitic transformation of the matrix.
Journal ArticleDOI
Effect of Biaxial Isothermal Quasi-Continuous Deformation on Structure and Shape Memory Properties of Ti-Ni Alloys
TL;DR: In this article, a mixed nanocrystalline and nanosub-grained structure with average grain/subgrain size below 100nm has been formed in a bulk sample as a result of severe plastic deformation at as low as 330°C.
Journal ArticleDOI
Evolution of microstructure in 100Cr6 steel after cooling from a thixoforming temperature to bainitic transformation ranges
TL;DR: In this article, a new concept for the isothermal heat treatment of thixo-elements, consisting of controlled cooling from a semi-solid metal processing (SSM) range, was proposed.
