The purpose of this study is to investigate the effect printing parameters on physical and mechanical properties additively manufactured ceramics (alumina zirconia). Sample parts were obtained by extrusion-based additive manufacturing a ceramic-binder mixture subsequent post-processing (debinding sintering). Their (microhardness, flexural strength, toughness) measured correlated with parameters...

Bu çalışmada, bor karbür (B4C) tozu ve çeşitli polimerik bağlayıcılar kullanılarak toz enjeksiyon kalıplama (TEK) besleme stoğu hazırlanmıştır. B4C ilavesinin stoğunundaki kritik yükleme değeri, reolojik bağlayıcı giderme davranışları üzerindeki etkisi farklı sıcaklıklarda rotasyonel reometre cihazı incelenmiştir. Hacimce %2,5’luk artışla %50-60 aralığında gerçekleştirilen incelemeler sonucunda...

Three-dimensionally printed fine-grained refractory ceramics ready for use in contact with liquid steel based on developed one-step thermal debindable ceramic filaments that do not require any chemical solvent pre-debinding are investigated. This work exhibits the most favourable debinding and sintering regimes an excellent form stability reproducibility of products ensured. The structure sinte...

Abstract Nano-phase separating Ni–12 at. pct Ag powders are processed via high-energy ball milling and brought into a supersaturated state with reduction of the grain size to nanocrystalline scale, combination that is designed encourage rapid densification by phase separation upon heating. This unstable powder then characterized dilatometry, in-situ x-ray diffraction, thermogravimetry microstru...

During the recent years powder processing technologies have gained much attention due to the less energy consumption and recyclable powders. Manufacturing of complicated parts by the conventional powder metallurgy (PM) method is hard due to the uniaxial pressure, which leads to the low design flexibility. In order to prevail these constraints, powder injection molding (PIM) process, which inclu...

We introduce a laser-based process relying on multiphoton-induced polymerization to produce complex three-dimensional (3D) glass parts. A focused, intense laser beam is used polymerize transparent resin, loaded with additives and silica nanoparticles, at the wavelength of through nonlinear absorption processes. The object created directly in volume, overcoming limitation layer-by-layer process....
