Thermomechanical modeling of IN718 alloy directed energy deposition process

Thermomechanical Properties of TiNi Shape Memory Alloy

The thermomechanical properties of shape memory effect and superelasticity due to the martensitic transformation and the R-phase transformation of TiNi shape memory alloy were investigated experimentally. The transformation line, recovery stress and fatigue property due to both transformations were discussed for cyclic deformation. The thermomechanical properties due to the R-phase transformati...

Modeling of Cone Deposition Process for Field

The Field emitter display (FED) is a very promising type of flat panel display. It possesses the potential to combine the performance of the Cathode Ray Tube with the compactness of the Liquid Crystal Display, while offering the additional advantage of low power consumption. The performance and reliability of the FED depend strongly upon the geometry of the deposited emitter cones. The formatio...

Structure and thermomechanical behavior of NiTiPt shape memory alloy wires.

The objective of this work is to understand the structure-property relationships in polycrystalline NiTiPt (Ti 42.7 at.% Ni 7.5 at %Pt) with a composition showing pseudoelasticity at ambient temperatures. Structural characterization of the alloy includes grain size determination and texture analysis while the thermomechanical properties are explored using tensile testing. Variation in heat trea...

Point process modeling for directed interaction networks

Network data often take the form of repeated interactions between senders and receivers tabulated over time. A primary question to ask of such data is which traits and behaviors are predictive of interaction. To answer this question, a model is introduced for treating directed interactions as a multivariate point process: a Cox multiplicative intensity model using covariates that depend on the ...
