A complete process chain for the additive manufacturing of metal components by means of Fused Filament\nFabrication (FFF) is being developed in a joint project. The final goal is to develop a process\nchain that provides ready-to-use parts of industrial quality at moderate investment cost. This...
Some elements like arsenic and antimony exhibit non-metal properties and are called metalloids Some higher metals like uranium and plutonium exhibit radioactivity and are used in nuclear power plants Some metals when bombarded with nuclear radiation give rise to new metals which themselves are very uns...
Heat treatment of titanium fibers is conducted to precipitate titania particles on the fiber surface, which may improve the biocompatibility of the metal. Control (non-heat treated) and heat treated short titanium fibers (250 μm long and 20μm diameter) were used as reinforcements at 3 volume...
On the crack resistance and damage tolerance of 3D-printed nature-inspired hierarchical composite architecture Authors demonstrate crack control of 3D printed composite architectures by leveraging crystallographic concepts of filament orientation in macroscale ‘grains’, enhancing structural complexity. ...

We developed a physical model to fundamentally understand the conductive filament (CF) formation and growth behavior in the switching layer during electroforming process in the metal-oxide-based resistive random-access memories (RRAM). The effects of the electrode and oxide layer properties on the CF...
Process-Property-Performance Relationship for Fused Deposition of Ceramics (FDC) Feedstock Materials Fused deposition of ceramics (FDC) is an extrusion based layered manufacturing process. It uses a high solids loaded (>50 vol. % ceramic or metal powder) thermoplastic binder in filament form as the...
(Fig.1a), but a sub-mm sized Au metal particle was found in the residual glass at the bottom of the silica crucible (Fig.1b), which indicates not all Au from the gold salt (HAuCl4) was incorporated as Au+ions in the glass. Indeed, solution inductively coupled plasma mass spectrometry...
Investigation of Metal-based Composites Vibration Properties Using Modal Analysis in Combination with Wavelet Transforms Under Imitation of Operational Loads The present article is dedicated to the study of the vibration properties of metal-based composite materials and the application of the non-destructive...
Our study of the simple ferromagnetic metal, Fe, may prove helpful to understand the causes of the interplay of extended defect structures and magnetism in more complex magnetic materials. Figure 1 The three Fe samples investigated: (a) single-crystal, (b) poly-crystal with a color code ...
