Ru is crucial in improving creep properties Nickel-based single-crystal superalloys. The effect of content on the behavior nickel-based superalloy was studied. exhibits unprecedented mechanical properties, increasing life at 1120 °C but decreasing it 1180 °C. This due to competition stress concentration formed between topologically close-packed phases and cavity. They are both related dissociat...

Nickel-based alloys are widely used in the aerospace industry, nuclear reactors and automotive industry. These exhibit excellent physical chemical properties at high temperatures. However, nickel-based difficult to machine materials with hardness low thermal conductivity, which results cutting forces during machining. Additionally, increasing demand for meso-scale components industry has opened...

A prototype endovascular electromechanical clot-extraction device was fabricated using a combination of shape memory polymer and shape memory nickel-titanium alloy (nitinol). Five embolic vascular occlusions were created in 4 rabbits by injecting thermally coagulated blood through a 4F catheter in the common carotid artery. Angiography immediately after clot injection showed complete or partial...

Bend it, shape it, remember it Shape-memory alloys have the useful property of returning to their original shape after being greatly deformed. This process depends on the collective behavior of many small mineral grains in the metal. Using threedimensional x-ray diffraction, Sedmák et al. tracked over 15,000 grains in a nickel-titanium shape-memory alloy as it moved through this transformation,...

A possible application of a metal powder composition made high-temperature nickel-based alloy with high heat strength (the material is analogous to Inconel 718) in selective laser melting (SLM, an additive manufacturing technology) was considered. Peculiarities formation the course have been researched, and mechanical properties were determined. The effect thermal treatment mode on characterist...

among the several non-conventional processes, electrical discharge machining (edm) is the most widely and successfully applied for the machining of conductive parts. in this technique, the tool has no mechanical contact with the work piece and also the hardness of work piece has no effect on the machining pace. hence, this technique could be employed to machine hard materials such as super allo...

In order to understand the beneficial effect of Pt on the adherence of thermally grown alumina scales, sessile drop experiments were performed to study the wetting of poly-crystalline alumina by nickel-aluminum alloys with or without platinum addition where the amount of Pt ranged from 2.4 to 10 at.%. Subsequent interfacial structure was evaluated using atomic force microscopy. Platinum additio...

Parameters identified to reduce and eliminate micro-hole sidewall tapering in nickel alloy C263.

High-precision magnetic micro-sensor is an interdisciplinary subject of magnetic field measurement techniques and micro-electromechanical systems (MEMS) technology. A micro-fluxgate magnetic sensor based MEMS technology was designed and fabricated in this paper. This device is a micro-magnetic sensor with a symmetric construction, closed magnetic circuits and differential form. A 25μm thick Flu...
