Introduction: The result of the treatment with fixed orthodontic appliances depends on the effective bonding of orthodontic brackets onto the teeth surface. Loosering of brackets during therapy means discomfort both for the orthodontist and patients

Fracture experiments on a polycrystalline Fe–2.3mass%V–0.12mass%P alloy show that the fracture mode is directly related to the grain boundary segregation of phosphorus. Comparison of the experimental data with theoretical simulations showed that

Multilayer pipes composed of various materials improve partially the properties of a pipe system and are frequently used in service. To estimate the lifetime of these pipes the basic fracture parameters have to be measured. In the contribution a new

Two-layer pipes made of PE 100 and PPH were chosen for the present study. The PPH pipe provided a protective layer for the PE 100 pipe. The relevant numerical model based on the finite element method (FEM) was used to calculate the stress distributio

Auger electron spectroscopy (AES) of in situ fractured samples was used to determine the grain boundary concentrations of phosphorus and silicon in polycrystalline Fe-Si-P alloys annealed at 800 °C for 100 h. These measurements were supplemented by

Aluminum-based alloys containing quasicrystalline particles of 50 – 600 nm in diameter as a reinforcing phase were produced in the form of powder or ribbons by water atomization or melt spinning techniques, respectively. Rods were compacted from po

The possibility of phase transformation toughening is demonstrated by the example of the β-modification isotactic polypropylene (β-iPP), which undergoes the β–α transformation (i.e., from hexagonal to monoclinic) during mechanical loading. The
