The permanent strengths of interstitial-free (IF) steels with different grain sizes and dislocation densities processed by severe plastic deformation (SPD) subsequent annealing are systematically investigated. Permanent strength, which is athermal time-independent, corresponds to the fundamental capability bear stresses caused external forces. Sufficiently long-time (24 h) stress relaxation tes...

The Nd-Fe-B hot-deformation magnet with high resistivity was successfully prepared by hot-pressing and of fast-quenched powder amorphous glass fiber. After the process optimization, increased from 0.383 mΩ·cm to 7.2 mΩ·cm. Therefore, eddy current loss magnets can be greatly reduced. microstructure shows that granular fiber forms a continuous isolation layer during hot deformation. At same time,...

Abstract Crumb rubber (CR) is generated from the recycling of used or discarded car tires and has long been utilized in paving industry. can be asphalt mixes two ways: dry process wet process. However, compared to standard combinations, crumb modified (CRMA) requires much higher mixing compaction temperatures. As a potential substitute, using warm mix (WMA) technology significantly lower hot-mi...

Abstract Practical assessment of subgrade settlement induced by train operation requires developing suitable models capable describing permanent deformation characteristics filling under repeated dynamic loading. In this paper, load triaxial tests were performed on coarse-grained soil (CGS), and the axial strain CGS different confining pressures stress amplitudes was analysed. Permanent behavio...

This paper presents a method for effectively modeling the outer surfaces of inlay/onlay prostheses restoring teeth that are partially destroyed. We exploit 3D mesh deformation techniques: direct manipulation free-form deformation (DMFFD) [9] and multiple wires deformation (MWD) [10] with three kinds of information: standard teeth models, scanned mesh data from the plaster cast of a patient's to...
