The manipulation of topography is crucial in surface engineering to customize material properties and functionalities for specific applications. Scientists have been inspired by natural surfaces found plants animals increasingly used engineered structures improve characteristics such as friction, wear, electrical resistance, wettability, antimicrobial behavior across various fields. Direct laser interference patterning (DLIP) a technique that can rapidly create well‐defined, periodic...
In this study, we report on phase formation and microstructure evolution in multiscale magnetron sputtered Ru/Al multilayers upon thermal annealing vacuum at slow heating rates of 10 K/min. By specifically adjusting the design as-deposited multilayers, certain desired phases can be tuned. We demonstrate that synthesis single RuAl thin films is possible a very controlled manner solid state only via activation without initiating self-propagating exothermic reactions multilayers. To investigate...
Parts for metallurgical applications made from refractory metal–ceramic composites offer improved thermal shock resistance due to their capability resistive heating compared ones solely ceramics such as Al 2 O 3 . The combination of and Nb is intriguing both show similar expansion behavior over a wide temperature range. high affinity form nonprotective oxides, however, hampers its use in oxidative environments. Formation phases at the ceramic–metal interface can have detrimental effects on...
Transition metal diboride-based thin films are currently receiving strong interest in fundamental and applied research. Multilayer based on transition diborides are, however, not yet explored detail. This study presents results the constitution microstructure of multilayer composed TiBx intermetallic compound NiAl. Single layer NiAl NiAl/TiBx with a variation individual thickness bilayer period were deposited by D.C. R.F. magnetron sputtering silicon substrates. The impact operation mode...
The self-propagating reaction in binary Al/Ru multilayers with two different bilayer thicknesses (89 and 178 nm, respectively) forming single-phase AlRu intermetallic compound is investigated experimentally by means of phase-field simulations. Experimentally, the time-temperature evolution free-standing films was recorded a high-speed pyrometer, resulting microstructure determined from electron backscatter diffraction measurements. model constructed based on minimization grand potentials for...
The intermetallic transition metal B2‐structured aluminide RuAl is a candidate material for use in various applications, including microelectronics and structural materials under demanding conditions, example, as oxidation‐ corrosion‐resistant materials. In contrast to other B2 aluminides, which usually suffer from brittle behavior at room temperature, exhibits comparatively good room‐temperature ductility, combination with further promising properties. Therefore, thin films are attracting...
A new method applied to the sensor proposed by Zhang et al. in 2018 is demonstrated this paper that combines benefits of design with fast heating possible nanocalorimetry. By applying a PID regulated pulse instead constant wattage, we unlock an accessible sense morphological changes occurring over short time periods would be invisible methods based only on heat capacity. In study, multilayer Ni/Al thin films were linearly heated at 25, 50, 100, and 200 K/s 700°C, showing two distinct peaks...
