“PARADOX” OF THE VOID NUCLEATION
East European Journal of Physics, 2014 On the basis of advanced before a method of phase diagrams martensitic transformations into systems such as « iron - carbon - vacancies », are determined energy of activation of formation of vacancies and voids.

The Long Trajectory of Rubber Physics: 3500+ Years and Counting
Journal of Polymer Science, EarlyView.Natural rubber's trajectory is traced from Mesoamerican use of Castilla elastica through vulcanization and the pneumatic tire to macromolecular physics and modern solid‐state refrigeration. Illustrations of C. elastica and an H. brasiliensis plantation frame the historical progression from indigenous material, then industrial crop and on to advanced ...

Spin Glass Model for the Study of Avalanches in Martensitic Transformations
, 1995 We present a simplified model which reproduces the evolution through avalanches found in athermal martensitic transformations. The model is based on the Random Bond Ising model driven with an external field which mimics the effect of either the external ...

Biomimetic robots driven by smart materials: Motion forms, stimulation methods and applications
Responsive Materials, EarlyView.Biomimetic robots enhance adaptability by mimicking biological systems, but rigid materials limit performance. Smart materials with stimuli responsiveness and shape adaptability enable more flexible actuation and improved environmental interaction.

Alloy Qualification for Producing Quench and Tempered Plate Steels with Extra‐Heavy Gage
steel research international, EarlyView.This study develops alloy concepts for ultraheavy steel plates (>100 mm) with ≥690 MPa yield strength. Through dilatometry and Jominy testing, the effects of Mo, Ni, and B on hardenability are quantified. A synergy between 0.5% Mo and 0.5%–1.0% Ni ensures core strength at low cooling rates, while boron microalloying suppresses ferrite and promotes ...

Micromechanics of stress-induced martensitic phase transformations [PDF]
, 2007 Martensitic phase transformation is a solid-solid transformation which represents the main deformation mechanism of shape memory alloys. The formed microstructure determines the mechanical and generally physical properties of the material and ...

Size Effects in Hysteresis of Reversible Martensitic Transformations [PDF]
, 2021 Martensitic transformations are diffusionless phase transformations, which have been observed in metals, ceramics, and electronic oxides. They are responsible for multifunctional behavior due to changes in shape, magnetization, and enthalpy associated ...

Geometry of polycrystals and microstructure
MATEC Web of Conferences, 2015 We investigate the geometry of polycrystals, showing that for polycrystals formed of convex grains the interior grains are polyhedral, while for polycrystals with general grain geometry the set of triple points is small.
