Keynote & Invited Speakers
Cihangir Duran (Turkey)
Cihangir Duran has received his B.Sc. degree from Metallurgical Engineering Department of the Middle East Technical University, Turkey in 1994 and Ph.D. from Materials Science and Engineering Department of the Pennsylvania State University, the USA in 2001. His studies embrace the synthesis and characterization of ceramic powders, processing-property relationship in (textured) functional and structural ceramics (e.g., piezoelectric ceramics, microwave ceramics, special compositions for the radome and LTCC-HTCC applications), design, fabrication and characterization of transducers and hydrophones for underwater applications. He is currently a faculty member at the Ankara Yıldırım Beyazıt University, Department of Metallurgical and Materials Science in Türkiye.
Compositional engineering of glass/ceramic composites for structural applications

Anorthite based glass/ceramic composites were studied for possible structural applications such as low-temperature co-fired ceramics and radomes. These materials require some optimized physical properties such as low densification temperature (<950°C), low dielectric properties (dielectric loss of 0.0007–0.006 at 1 MHz and dielectric constant of 3.8–9.2 at 1 MHz), good thermal properties (thermal conductivity of 2.0–4.5 W/m·K), a matched thermal expansion coefficient (4.5–7.5 ppm/°C) to the silicon or GaAs as well as optimum mechanical properties (Young’s modulus of 80–150 GPa, the flexural strength of 116–320 MPa). A CaO–SiO2–Al2O3-based composition was used as the glass matrix phase, Al2O3 and mullite were used as the crystalline phases.
Nano h-BN and AlN fillers were particularly added to improve thermal properties. Effect of composition (i.e., glass/ceramic ratio, nano filler amount) on densification, phase formation, microstructural development, thermal, dielectric and mechanical properties of the composites will be discussed from the structural applications of points of view.

Today, more than 5 % of electricity consumption in the world is lost in the form of energy loss in devices as transformers. The losses reduction, with a positive impact on the environment, can be achieved by the development of new materials with enhanced electromagnetic properties. Soft magnetic composites (SMCs) are a new class of materials designed in a way to combine the key advantages of the main classes of soft magnetic materials (high electrical resistivity of the ferrites and high saturation induction and permeability of the electrical steels). SMCs are prepared via powder metallurgy routes using ferromagnetic particles coated with a dielectric layer and then compacted. Recently, a new concept for designing SMCs was developed using ferromagnetic fibres instead of powders, i.e. Fibres-based Soft Magnetic Composites. This change leads to a significant enhance of the electromagnetic properties of classic SMCs, and will be the central point of the presentation.
Keywords: Soft Magnetic Composites, Fibres-based Soft Magnetic Composites, Cold Sintering, Magnetic Properties.
