Decomposition and crystallization of Pd40Cu30Ni10P20 and Zr46.8Ti8.2Cu7.5Ni10Be27.5 metallic glasses

The Pd40Cu30Ni10P20 and Zr46.8Ti8.2Cu7.5Ni10Be27.5 bulk glasses exhibit extraordinary stability against crystallization. It is assumed, that this results from the complicate crystallization behavior, which requires strong decomposition of the glass i

A single-crystalline ferromagnetic Ni-Mn-Ga shape memory specimen was deformed in the martensitic state by uniaxial compression to a total strain of 2%. The stress-strain curve displays a yield point at 6 MPa followed by jerky flow. After mechanical

Icosahedral Al-Pd-Mn single quasicrystals were deformed between room temperature and 400°C by Vickers hardness testing. The surface morphology was investigated by profiling and scanning electron microscopy. Specimens were prepared for cross-sectiona

A survey is given on results of experimental studies of the plastic deformation of icosahedral quasicrystals. In particular this concerns the stress-strain characteristics and the determination of the thermodynamic activation parameters of the deform

A technique is presented to determine quantitatively the phason strain fields in quasicrystals by electron diffraction analysis in a transmission electron microscope. The deviation vectors of diffraction spots from their ideal positions are measured

Scientists have studied the mechanical properties of quasicrystalline materials for quite some time. However the difficulty in obtaining material of reasonable quality hampered systematic investigations. The progress in materials preparation in recen
