Manufacturing bulk nanostructured materials with least grain growth from initial powders is challenging because of the bottle neck of bottom-up methods using the conventional powder metallurgy of compaction and sintering. In this study, bottom-up type powder metallurgy processing and top-down type SPD (Severe Plastic Deformation) approaches were combined in order to achieve both full density and grain refinement of metallic powders. ECAP (Equal-Channel Angular Pressing), one of the most promising processes in SPD, was used for the powder consolidation method. For understanding the ECAP process, investigating the powder density as well as internal stress, strain and strain rate distribution is crucial. We investigated the consolidation and plastic deformation of the metallic powders during ECAP using the finite element simulations. Almost independent behavior of powder densification in the entry channel and shear deformation in the main deformation zone was found by the finite element method in conjunction with a pressure dependent material yield model. Effects of processing parameters on densification and density distributions were investigated.

The Proceeding contains papers based on invited keynote speeches and oral presentations at the International Conference on Digital & Empathic Architecture & Civil Engineering (DEACE 2021) and International Student Workshop. The event was organized by the Faculty of Civil Engineering & Planning, Petra Christian University (PCU), Surabaya, Indonesia on August 20th-21st, 2021 for the international conference and August 12th-21st, 2021 for the workshop as a series of events celebrating the 60th Anniversary of Petra Christian University. The event covered several topics: ‘Structural Engineering and Materials’, ‘Building Science and Technology’, ‘Construction Management’, and ‘Architecture and Urban Development’. DEACE presented a theme: “Digital and Empathic Engagement in the New Era for Architecture and Civil Engineering”. Digital engagement can revolutionize approach to design and engineering while supporting opportunities to accommodate the implementation of advanced technology. While empathic engagement reflects not only on effectively design and build infrastructure to meet safety and other regulatory requirements, but also understanding customer essential needs. DEACE aimed to gather researchers, scholars, and practitioners all over the world to share and exchange their knowledge and breakthrough in the fields of Architecture and Civil Engineering especially toward the new era. As the event was approaching and there was no sign of the Covid-19 pandemic slowing down earlier that year, it was decided not to postpone the event but to hold it virtually instead. The conference started with plenary sessions with four keynote speakers, and followed by parallel sessions in two rooms with four sessions. Each keynote speech took 45 minutes and 30 minutes for presentation and discussion, respectively. While speakers in parallel sessions were given 15 minutes and 5 minutes for presentation and discussion. The were 30 presenters out of 159 participants in total, consist of both academicians and professionals. They came from Indonesia as well as some other countries such as China, Taiwan, Germany, Japan and Australia. Zoom video conferencing application was used in the event which served the event very well.
