Ultrasonic assisted-ECAP

Ultrasonics, 2013
Equal channel angular pressing (ECAP) is one of the most prominent procedures for achieving ultra-fine grain (UFG) structures among the various severe plastic deformation (SPD) techniques. In this study, the effect of ultrasonic vibration on deformation behavior of commercial pure aluminum in the ECAP process is analyzed successfully using three ...

Subgrain Boundaries in ECAP Aluminium

Materials Science Forum, 2007
The effect of ECAP technology on the subgrain structure of coarse-grained pure aluminium is described by means of the orientation imaging microscopy (the selected lower bounds of misorientation (disclination) are = 2o, 5o, 10o and 15o). Standard profile and intercept counts carried out in three suitably oriented and mutually perpendicular section ...

Temperature Effects of ECAP and Annealing after ECAP on Microstructure of TA15 Alloy

Advanced Materials Research, 2010
A study was conducted by optical microscope (OM) and transmission electron microscope (TEM) on the microstructure evolution of TA15 alloy by severe plastic deformation (SPD) and annealing after SPD. In this study, equal channel angular pressing (ECAP) was taken as the method of SPD.

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)

Thermal stability of ECAP processed pure copper

Materials Science and Engineering: A, 2007
Abstract 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, 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.
