Journal of the Society of Materials Science, Japan, 2006 Equal channel angular pressing (ECAP) invented by Segal was applied successfully to metal process of aluminum and magnesium alloys for increasing their strength by fining the grain size. But a little attention has been paid to its application to polymers.

Enhancing Ductility of ECAP Processed Metals
Materials Science Forum, 2010 Mechanical 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 ...

Journal of Mechanical Engineering and Sciences, 2020 The grain growth of an ultrafine-grained iron-chromium alloy has been investigated focusing on the early stage of restoration of strain. Ultrafine-grained (UFG) material has been prepared by equal channel angular pressing (ECAP) up to eight passes via ...

Producing High‐Strength Metals by I‐ECAP [PDF]
Advanced Engineering Materials, 2015 Incremental equal channel angular pressing (I‐ECAP) is used in this work to produce ultrafine‐grained (UFG) pure iron, aluminum alloy 5083, commercial purity titanium (grade 4), and magnesium alloy AZ31B. Pure iron is processed at room temperature, aluminum alloy at 200 °C, titanium at 320 °C, and magnesium alloy at 150 °C.

Nebular Spectra and Explosion Asymmetry of Type Ia Supernovae
, 2009 The spectral signatures of asymmetry in Type Ia Supernova (SN Ia) explosions are investigated, using a sample of late-time nebular spectra. First, a kinematical model is constructed for SN Ia 2003hv, which can account for the main features in its optical,
