Evolução do tamanho de grão e comportamento mecânico do magnésio comercialmente puro submetido a tratamento termo-mecânico de ECAP
(Universidade Federal de Minas GeraisUFMG, 2015-01-16)
In this work samples of commercially pure magnesium were processed by ECAP (Equal Channel Angular Pressing), in moderate temperatures, using a die with angle of = 135° between the two channels. An intermediate step of ...
Magnesium Alloys for Hydrogen Storage Processed by ECAP Followed by Low Temperature Rolling
(Univ Fed Sao Carlos, Dept Engenharia Materials, 2022-01-01)
The hydrogen storage properties of pure magnesium and magnesium ZK60 alloy containing 2.5 wt% of mischmetal (Mm) processed by Cold Rolling (CR) and Low Temperature Rolling (LTR) were investigated. Before CR and LTR processing, ...
Microstructure and strengthening mechanisms in an Al-Mg-Si alloy processed by equal channel angular pressing (ECAP)
(Springer London Ltd, 2018-03)
The microstructure, mechanical properties, and strengthening mechanisms of an Al-Mg-Si alloy (AA6060) subjected to severe plastic deformation using equal channel angular pressing (ECAP) were investigated. Samples were ...
