Microstructural and Hardness evolution of AZ80 alloy after ECAP and post-ECAP processes
Materials Today: Proceedings, 2018Abstract This research paper investigates the microstructure evolution and hardness variation of wrought AZ80 magnesium alloy after each ECAP passes. The strengthening effect of AZ80 alloy was examined after post-ECAP aging treatment. Alloys were severely deformed through equal channel angular press at 533K using route Bc with a die channel angle (ϕ)

Thermal stability of ECAP processed pure copper
Materials Science and Engineering: A, 2007Abstract Microstructure and texture evolution of pure copper (99.95%) after equal-channel angular pressing (ECAP) with route Bc up to 12 passes and subsequent heat treatment were investigated. After deformation the samples were annealed at different temperatures. The deformed and annealed states were characterized by X-ray pole figures, electron back

Structure and properties of AlMg alloy after combination of ECAP and post-ECAP ageing
Archives of Civil and Mechanical Engineering, 2016Abstract Equal channel angular pressing technique (ECAP) was used before and after solution heat treatment to obtain grain refinement and strengthening of commercial Al–Mg casting alloys. The experiments were performed to investigate the strengthening effect of the alloy after various post-ECAP ageing treatments.

Development of Homogeneity in an Al-6061 Alloy Processed by ECAP and ECAP-Conform
Materials Science Forum, 2014Equal-channel angular pressing (ECAP) has been established as an effective method to achieve ultrafine-grained materials and ECAP combined with the Conform process (ECAP-Conform) is considered a promising candidate to realize continuous processing by ECAP.

Strength and structure of AlMg3alloy after ECAP and post-ECAP processing
Materials and Manufacturing Processes, 2016ABSTRACTEqual-channel angular pressing (ECAP) is a promising method for the processing of metals with an ultrafine-grain (UFG) structure of a few hundred nanometers in size. In this paper, the influence of solution treatment and artificial aging conditions, combined with a severe plastic deformation process on the AlMg3 aluminum alloy, was studied ...

Inhomogeneity of Microstructure and Creep of ECAP Aluminium
Materials Science Forum, 2006High purity (99.99%) pure aluminium processed by equal channel angular pressing (ECAP) was examined in terms of the ECAP microstructure inhomogeneity and its creep behaviour. The results indicate that an inhomogeneity of the ECAP microstructure in mesoscopic scale may influence the creep behaviour of the pressed material.

Grain size and homogeneity are influence to aluminium properties, Equal channel angular pressing (ECAP) can produce aluminium with ultra fine grain Size (UFG). The grain size is depends on ECAP Dies geometry (Channel angle Φ, Fillet radius ψ) and friction, taguchi method used to find the optimum dies geometry its can produce smaller grain ...

Texture During ECAP and Post ECAP Simple Compression of Commercial Purity 1050 Aluminum Alloy
ASME 2008 2nd Multifunctional Nanocomposites and Nanomaterials, 2008Electron back scattered diffraction (EBSD) was used to document the texture developed during ECAP. Samples of commercial purity aluminum processed to 8 passes through route BC and route C were examined on two planes (flow plane and the plane normal to the extrusion direction) and pole figures and orientation distribution function plots (ODFs) were ...

Ecap IIߞAn electronic circuit analysis program
IEEE Spectrum, 1971Ecap II, a nonlinear dc and transient circuit analysis program, uses a free-format, problem-oriented language for describing circuit parameters and topology. Its computation speed is high enough to make the transient analysis of kilobranch nonlinear circuits feasible.
