Molecular dynamics simulation of martensitic transformations in NiAI
Autor: Y. Shao, Philip C. Clapp, J. A. Rifkin
Publikováno v: Metallurgical and Materials Transactions A. 27:1477-1489
Both thermally induced and stress-induced coherent nucleation and growth of an L10 martensitic phase have been examined and analyzed at the atomic level in molecular dynamics (MD) computer simulations of an ordered B2 NiAl lattice array using embedde

Static and dynamic precursors of displacive transformations near crystalline defects
Autor: Philip C. Clapp
Publikováno v: Physica D: Nonlinear Phenomena. 66:26-34
An exact nucleation energy formula has been derived for the fluctuation energy necessary to initiate a coherent martensitic transformation in the strain field of a defect of arbitrary potency within the framework of a standard Ginzburg-Landau strain

The critical role of defects in first-order displacive transformations
Autor: Philip C. Clapp
Publikováno v: Materials Science and Engineering: A. 127:189-195
This overview will survey efforts that have been made to date to answer essentially three questions. 1. (1) Are defects essential for first-order displacive transformations? 2. (2) If so, which are those defects? 3. (3) What is the energy and the con

Computer Simulation of Fracture, Dislocations and Martensitic Transformation in Solids
Autor: Philip C. Clapp
Publikováno v: Stability of Materials ISBN: 9781461380283
In the past decade or so computer simulation has become a principal method for investigating and predicting a wide variety of material properties. In fact it is now routinely used to interpret experiments, or to test theoretical models, or to make ne

Pretransformation effects of localized soft modes on neutron scattering, acoustic attenuation, and Mössbauer resonance measurements
Autor: Philip C. Clapp
Publikováno v: Metallurgical Transactions A. 12:589-594
The localized soft mode model of martensitic nucleation is used to predict pretransformation effects of such regions on inelastic neutron scattering, ultrasonic acoustic attenuation and Mossbauer resonance absorption. The theoretical predictions are

Growth dynamics study of the martensitic transformation in Fe-30 pct Ni alloys: Part II. Computer simulation of martensitic growth
Autor: Zhen-Zhong Yu, Philip C. Clapp
Publikováno v: Metallurgical Transactions A. 20:1617-1629
The growth of the shear-type martensitic transformation in an Fe-30 pct Ni alloy has been studied using molecular dynamics (MD) computer simulations. A semiempirical method is used to construct the interatomic potential including the conduction elect
