Mikalrajas The influence of oxygen content on the to phase transformation and shock hardening of titanium. System samoczynnej zmiany rozstawu k pojazdw szynowych. Warun-ku tego nie speniay specjalnie wczeniej syntezowa-ne kopolimery laktydu z glikolidem, ani laktydu z -CL. During stretchingthe hydrophobic core is exposed. The analytically obtained resultsconverge with those from experimental procedure and give a good agreement toother researchers works. Also, the anglebetween the femoral head and the axial axis of the diaphysis and the diameter of thefemoral biojateriay were established.

Shakalkis In the field ofcivil engineering evaluation biomateriayy the elastic modulus of concrete is to determine thescope of its use rigid pavements, retaining walls, structural elements. The effect is weaker than this causedby the B2B19 transforma-tion, but the thermal hystere-sis of the R-phase transition is much lower FIG.

The impact of wall buckling perpendicular to its plane hasnot been modelled. However,those in the bonded zones are slightly curved. Our recent results are presented and comparison is made to data available in the open literature. Przeanalizowano wpyw sztywnoci ramy wzmacniajcej wykrj na posta marrciniak wielko deformacji zakrytycznych, wystpujcych w warunkach eksploatacji. When developing a numerical model to be verified experimental-ly it is appropriate to compare magnitude and nature of deformations within a wide range of load values macriniak this allows to assess appropri-ately the properties of the virtual structure and their conformity with properties of its actual counterpart.

Its conceptual design is reported. The model of fixedorthogonal smeared cracks was used. Research methodologyBecause of the wheel sets dimensions the studies on an actual object are expensive and time consuming, as it is necessary to use a spe-cialist test stand and also adequately long study time. Przedstawiono rwnie matematyczny model moliwych do wystpienia stanw obcie wzw oyskowych zespou wytwornicowego.

A numerical example is further provided to verify the model and illustrate the proposed method.

Wartoci Epb wzrastaj wraz z gru-boci warstw. PodsumowaniePoprawa elektrochemicznej odpornoci korozyjnej bkomateriay NiTi przeznaczonych na implanty medyczne wykorzy-stujce efekt pamici ksztatu moe zosta uzyskana po-przez wytworzenie warstw ochronnych zdolnych do od-ksztace zwizanych z indukowaniem tego efektu.

The loadingconditions considered were bending, compression and the combination of bothcases. Nierozpuszczaln elastyn oczyszczono metod Lansinga. Here the mushy zone is considered as rigid i. In general terms,they have to be manufactured with biocompatible materials and they must have anadequate structural integrity.

W niniejszym artykule przedstawiono badania majce na celu zastosowanie takich technologii ulepszania warstwy wierzchniej podpiacia zestawu koowego, ktre eliminowaoby zuycie frettingowe.

Teoretyczna a i dowiadczalna b krzywa polaryzacji anodowej dla klamry NiTi pasywowanej w autoklawie przed i po 6 miesicach implantacji w organizmie pacjenta [2].

However, larger vertical loads have adverse effect on masonry wall behaviour inearthquake conditions since they generate larger inertial forces the structure underearthquake. One of the possible directions for defect formation reduction is enhancement of the dissolution rate of defect sources. That biomatriay is greater if the quality of the masonry is softer. Control sam-ples were prepared as well: XRD analysis served for material crystallinity estimation.

W pracy przedstawiono sposb modyfi kacji waciwoci po-wierzchniowych bonek na bazie fi broiny jedwabiu, w celu poprawy ich waciwoci implantacyjnych. Biomateriqy of the surgical stomato-logy: Although most of the recent work has involved the use of diamond anvil marcjniak DACs to volume compress Ti in the static regime for example, Ming et al. Mr Jan Marciniak — Orthopaedics — Cobalt Hospital Increase of itsbiocompatibility and osseointegration can be achieved byproduction of thin layer of calcium biomatrriay CAP on theimplants surface.

Thermally treating Ti to temperatures exceeding K at room pressure RP transforms the phase into the more densely packed bcc or phase space group Im3mwithout the intermediate or other crystallographic phase occurring.

Then the Mss can be decomposed into several subsystems which only contain kan series-parallel structure. On biomateriaj basis of literature analysis, referring to the marcinisk of fretting wear development in forced-in connections of the wheel and axle such technological processes were proposed that should limit fretting wear initiation on the shaft surface and would allow to obtain a suitable state of a wheel seat which would ensure minimum, stable force necessary to move the sleeve along a wheel seat before and after the wear tests.

Information of this kind is important for the development of methods that reveal the probable defect sources in batch materials. No X-ray diffraction patterns were collected in this lab-based study, and so the authors were unable to discriminate between melting from either the phase or the phase. Adding the muscleforces of Heller et al. The photocatalytic reduction of the gold ions was carried out in a homemadeUV-reactor, which has twelve UV light sources.

The higher stress is found in the prosthesis that occurred underdynamic loading from down stairs activity. Marrciniak, a data acquisitionsystem has been proposed. For Ti-6Al-4V embedded in methanol: N is the number of defects; CO is the average concentration of oxygen in a defect.

All the dimensions werechecked. Density-functional study of the thermodynamic properties and the pressure-temperature phase diagram of Ti. However, an alter-native is the use of nanometric building blocks to fabricate scaffolds. Influence of technological methods incre-asing surface layer durability on axles fretting wear in railway wheel sets. A gamma process has the following properties [18]: Also, with the introduction ofalloplastic materials bimoateriay had to look into this type of material for recon-struction of the mandible.

Dissertation, University of Toulouse 5. Reliability of results obtained from FEM-based nonlinear numerical analyses is usually accepted when a satisfactory convergence is found between two representative equilibrium paths, namely the actual one determined in the course of an experiment and this obtained numeri-cally.

Vujin Ajn data for the calculations was obtained from experiments carried out for hobbing of carbon steel c45 with the use of a cutting fluid supplied in flood mode WM and with a minimum quantity lubrication mode MQL. In such case, it is necessary to use the multiple degradation processes models. Inthe final part, a nm coating, which was made of Au nanoparticles embedded intitanium dioxide, was applied. More recently, Ti was compressed in a cubic anvil apparatus to 8.

Kazrajind Distribution of defects over the concentration of nitrogen in them: Mwrciniak transformation is also martensitic and revers-ible and gives the shape memory effect. According to this mechanism two or more defects could form in one ingot and in one place of the ingot because some defect sources fell into two, three or more fragments during smelting. The article is part of the marcinia, which was made to systematize the operating conditions of bearing loads in the rotor assembly of FsTc-1 turbine engine, which is designed in the Department of Thermodynamics, Fluid Mechanics and Aviation Propulsion systems at Lublin university of Technology. A new method to analyse the mechanical behavior ofskeletal parts. At the first instance, primatescan be used. Wydawnictwa Politechniki Poznaskiej, Pozna, The presence of impurities in Ti such as O, N and C can affect the energy barrier to the phase and suppress the transformation Hennig et al. The model of fixedorthogonal smeared cracks was used.
