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.

The Status and Development of ECAP
Applied Mechanics and Materials, 2014ECAP is a large plastic deformation processing technology, ultrafine-grained materials can be prepared using ECAP process. This paper reviews the channel angular extrusion process application in aluminum alloy, copper alloy, magnesium alloy and composite materials and so on.

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.

A new approach for the determination of ECAP thresholds
Cochlear Implants International, 2017Electrically 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

Enhancing Ductility of ECAP Processed Metals
Materials Science Forum, 2010Mechanical properties such as hardness, mechanical strength or fatigue resistance are by far the most successful material behaviour improved by the ECAP processed. However, the lack of ductility is the most critical negative effect. Combination of multimodal grain size is one of the most promising solutions to improve the strength/ductility balance ...

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)

Channel Configuration Effects in 3D-ECAP
Materials Science Forum, 2006This 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.

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.

Introduction to the Ninth ECAP Newsletter
European Child & Adolescent Psychiatry, 1999The 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).
