Quantum tic-tac-toe: A teaching metaphor for superposition in quantum mechanics

American Journal of Physics, 2006
Quantum tic-tac-toe was developed as a metaphor for the counterintuitive nature of superposition exhibited by quantum systems. It offers a way of introducing quantum physics without advanced mathematics, provides a conceptual foundation for understanding the meaning of quantum mechanics, and is fun to play.

Preparation of Ti(C,N)-WC-TaC solid solution by mechanical alloying technique

Journal of Materials Processing Technology, 1995
Abstract Mechanical alloying (MA) is a dry, high energy ball milling process for producing composite metallic powders with a fine controlled microstructure. Traditionally, the raw materials used in MA must include at least one fairly ductile metal to act as a host or binder to hold together the other ingredients.

Structure Prediction and Mechanical Properties of Tantalum Carbide (TaC) on ab initio Level

Zeitschrift für anorganische und allgemeine Chemie
AbstractTantalum carbide (TaC) is an extremely hard, brittle, refractory ceramic material with excellent physical properties, which makes it a desirable material in e. g. aerospace industries. In order to explore the range of feasible modifications of TaC, we have executed a crystal structure prediction study of the TaC chemical system using a multi ...

Effects of TaC addition on microstructure and mechanical properties of SiBCN composite ceramics

Ceramics International, 2019
Abstract In this work, SiBCN–TaC composite ceramics were prepared by a combination of mechanical alloying and reactive hot-pressing sintering techniques. The effects of TaC addition on microstructure, mechanical properties and oxidation resistance of the resulting composite ceramics were studied in detail. Results suggested that the as-sintered SiBCN–

Microstructure evolution, mechanical properties and strengthening mechanism of refractory high-entropy alloy matrix composites with addition of TaC

Journal of Alloys and Compounds, 2019
Abstract This study focuses on novel refractory MoNbRe0.5W(TaC)x high-entropy alloy matrix composites synthesized by vacuum arc melting. The microstructure evolution, compressive mechanical properties at room temperature and strengthening mechanism of the composites with addition of TaC are analyzed and discussed.

Wear mechanisms in high speed steel reinforced with (NbC)p and (TaC)p MMCs

Wear, 2000
Abstract Powder metallurgy techniques were used to manufacture metal matrix composites. M3/2 high-speed steel was used as the matrix, and NbC and TaC, in different percentages, as reinforcements. Graphite was added to the M3/2 powders, to compensate carbon losses during sintering, and copper–phosphorous (Cu–P) to promote liquid phase sintering.
