Development of Homogeneity in an Al-6061 Alloy Processed by ECAP and ECAP-Conform

Materials Science Forum, 2014
Equal-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.

Structure and properties of AlMg alloy after combination of ECAP and post-ECAP ageing

Archives of Civil and Mechanical Engineering, 2016
Abstract 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.

A new approach for the determination of ECAP thresholds

Cochlear Implants International, 2017
Electrically evoked compound action potentials (ECAPs) of the auditory nerve are routinely recorded for testing the cochlear implant integrity and its functional connection to the auditory system. The response thresholds derived from ECAP recordings are widely used as a helpful guide in the fitting of the dynamic range of electric stimulation, although

Microstructural and Hardness evolution of AZ80 alloy after ECAP and post-ECAP processes

Materials Today: Proceedings, 2018
Abstract 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)

Channel Configuration Effects in 3D-ECAP

Materials Science Forum, 2006
This paper explains the concept of 3D-ECAP with “in-die rotation” and presents the results of experiments for two sets of tooling with channel passages orientated at 90° and 120°. The results for aluminium 1070 are compared in terms of the process force, billet end effects, mechanical properties and structure of the material.

ECAP-Supplementary

We consider unsupervised domain adaptation (UDA) for semantic segmentation in which the model is trained on a labeled source dataset and adapted to an unlabeled target dataset. Unfortunately, current self-training methods are susceptible to misclassified pseudo-labels resulting from erroneous predictions.

Strength and structure of AlMg₃alloy after ECAP and post-ECAP processing

Materials and Manufacturing Processes, 2016
ABSTRACTEqual-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 ...

Introduction to the Ninth ECAP Newsletter

European Child & Adolescent Psychiatry, 1999
The process of establishing child and adolescent psychiatry as a mainstream medical subspecialty in our country began forty years ago. The studies began in Istanbul University between 1956±1957. The ®rst child psychiatric clinic was founded in Hacettepe University in 1959 andwas soon after followed by the others (Cebiroglu andOE zbek 1990).

A Comparison Between Numerical and Analytical Modeling of ECAP

2014
Recent developments in nanostructured products draw considerable attention to ultrafine grained materials. These materials are normally manufactured by different severe plastic deformation (SPD) methods. In the present study, analytical models and finite element method (FEM) are used to calculate strain imposed to a specimen that was deformed by equal ...
