Experimental results on hot deformation and dynamic structural processes of nickel based alloy Inconel 718 are reviewed. The focus is the analysis of dynamic precipitation processes which operate during hot deformation of these materials at elevated temperatures. Hot compression tests were performed on the solution treated precipitation hardenable nickel based superalloy Inconel 718 at 720-1150...

This article reports the flow stress behaviour of ASTM A335 P92 steel. Uniaxial isothermal compression experiments were conducted to examine hot deformation steel in a Gleeble® 3500 thermal–mechanical simulator. The test conditions 0.01–10 s−1 strain rate and 850–1000 ℃ temperature. Constitutive equations processing maps developed used describe process. results showed that stress–strain curves ...

The connection method of lengthening the steel tube hollow concrete-filled sandwich circular tubes and threaded connections is proposed. length, depth position are basic parameters. Twelve concrete pipes with were designed subjected to axial compression tests. compressive loading–longitudinal displacement curves, loading strain curves failure mode specimens analyzed, effects different parameter...

The objective of the present research was to study effect temperature on mechanical properties, failure mode and uniaxial compression constitutive relationship a modified polyurethane concrete. A total 24 cube 27 prism specimens were fabricated, uniformity concrete checked. compressive test, splitting tensile test static carried out at 0, 15, 40 60 °C. mode, strength, axial elastic modulus stre...

This paper derives kinematic admissible bending moment – axial force (M-P) interaction relations for mild steel by considering strain hardening idealisations. Two models for strain hardening – Linear and parabolic have been considered, the parabolic model being closer to the experiments. The interaction relations can predict strains, which is not possible in a rigid, perfectly plastic idealizat...

The high fine-aggregate content of Self-Compacting Concrete (SCC) means that its deformational behavior differs from vibrated concrete. SCC performance is further altered when industrial by-products are used as raw materials in those fractions. In this paper, the aim to analyze and model under compression bending containing 100% coarse 0%, 50%, fine Recycled Aggregate (RA), limestone RA green a...

The superelastic properties and stress-induced martensite (SIM) stabilization have been studied in a shape memory Ni51.1Fe16.4Ga26.3Co6.2 single crystal. crystal, characterized by thermally induced forward martensitic transformation temperature around 56 °C the initial state, has submitted to compression mechanical testing at different temperatures well above, near below (MT). After each test, ...
