Dynamic Recrystallization under Hot Deformation of a PH Stainless Steel

Dynamic recrystallization, DRX, behaviour of a precipitation hardened, PH, stainless steel was studied in connection with microstructural developments in a compression test. The experimental results showed that the dominant mechanism of softening is DRX, but at high strain rates and low temperatures, ie, high Zener-Holman parameter, Z, work hardening and dynamic recovery, DRV, produced a pancke...

Point-based Dynamic Deformation and Crack Propagation

In this paper, we articulate a novel meshless computational paradigm for the effective modeling, accurate physical simulation, and rapid visualization of solid objects. The uniqueness of our approach is that both the interior and the boundary of our new volumetric representation are point-based, generalizing the powerful and popular method of point-sampled surfaces. We also build the point-base...

A Homodyne Quadrature Laser Interferometer for Micro-Asperity Deformation Analysis

We report on the successful realization of a contactless, non-perturbing, displacement-measuring system for characterizing the surface roughness of polymer materials used in tribological applications. A single, time-dependent, scalar value, dubbed the collective micro-asperity deformation, is extracted from the normal-displacement measurements of normally loaded polymer samples. The displacemen...

Phase Transformation in Tantalum under Extreme Laser Deformation

The structural and mechanical response of metals is intimately connected to phase transformations. For instance, the product of a phase transformation (martensite) is responsible for the extraordinary range of strength and toughness of steel, making it a versatile and important structural material. Although abundant in metals and alloys, the discovery of new phase transformations is not current...
