2. Effect of titanium and nitrogen inoculation on the microstructure, mechanical properties and abrasive wear resistance of Hadfield Steels
Abstract The effect of titanium and nitrogen addition on Hadfield steels was investigated. In order to do this, two grades of steels were produced in terms of titanium and nitrogen addition. The final samples had their microstructure characterized and their mechanical properties were evaluated by uniaxial tensile and Charpy impact tests. Furthermore, the wea

3. Prediction of Mechanical and Functional Features of Aged Rubber Composites Based on BR/SBR; Structure-Properties Correlation
In this study, the structure-properties relationship between the thermal factors of BR/SBR blends [normalize factor h BR 100 hBR 100 − hBR x, and the maximum peak temperature difference of thermal decomposition of BR and SBR Δ T max = T max BR − T max SBR ] with their aging time (1 to 40 days) was demonstrated using DTG profile of uncu

4. New nonlinear solution of nearly incompressible hyperelastic FGM cylindrical shells with arbitrary variable thickness and non-uniform pressure based on perturbation theory
Abstract In this paper, nonlinear analysis of thick cylindrical shells with arbitrary variable thickness made of hyperelastic FGM with radially variation of material properties in nearly incompressible state under non-uniform pressure loading is presented. Thickness and pressure of the shell vary in axial direction by linear and/or nonlinear functions. The g

5. Materials from renewable resources: new properties and functions
Abstract: Sustainable production requires increasing use of raw materials from renewable sources, processed under mild conditions with minimal effluent production. These requirements are satisfied by using materials derived from biomass, in synergy with food and energy production. The possibilities of biomass are continuously enlarged by new findings, as in

8. Influência do envelhecimento termo-oxidativo nas propriedades mecânicas e de amarelamento de blendas de poliestireno com borracha reciclada de estireno-butadieno (SBR)
RESUMO Este trabalho teve como objetivo avaliar o envelhecimento termo-oxidativo, nas propriedades mecânicas e de índice de amarelamento (YI), de blendas de poliestireno com borracha reciclada (SBRr), compatibilizadas. As blendas foram preparadas, inicialmente, em uma extrusora de rosca dupla corrotacional e, posteriormente, os grânulos extrudados foram m

9. Cellulose Nanocrystals and Jute Fiber-reinforced Natural Rubber Composites: Cure Characteristics and Mechanical Properties
A comparative study was conducted for three natural rubber (NR) composites: one containing raw jute fibers, one containing bleached jute fibers, and one containing cellulose nanocrystals (CNCs). The composites were prepared by adding each filler at 5 or 10 phr to the latex before chemical coagulation, and the composites were processed in a two-roll mixing mi

10. Thermo-mechanical analysis of mass concrete elements made of rubberized concrete
Resumo Neste estudo, foram avaliadas amostras de concreto massa com borracha (concreto emborrachado) para determinar se a adição de partículas de borracha aumentaria a resistência à fissuração devido a variações volumétricas de origem térmica, em comparação com um concreto de referência, sem borracha. Amostras dos concretos estudados foram inic

12. Effects of Rotor Speed on Peroxide/Bismaleimide Cured Polypropylene/Nitrile Rubber Thermoplastic Vulcanizates (TPVs)
Elastomer thermoplastics are a class of polymeric materials that received industry attention due to the possibility of joining the elastic of elastomers with the thermoplastics processability. The synergistic properties are linked to the appropriate processing. This study evaluated the effect of rotor speed during polymer mixing and the dynamic vulcanization
