Strain hardening and heterogeneous deformation during twinning in Hadfield steel
We identify the role of deformation twinning and twin–twin intersections on the strain hardening behavior of Hadfield steel single crystals using strain field measurements. In situ and ex situ strain field measurements resolved at micrometer length scales are obtained using digital image correlation. Ex situ measurements reveal that macroscopic twin-bands, which are composed of a mixture of fin...
متن کاملStrain hardening behavior of aluminum alloyed Hadfield steel single crystals
Very high strain hardening coefficients (=G/23) are observed for aluminum-alloyed face-centered cubic Hadfield steel single crystals under tensile loading. Alloying with aluminum suppressed deformation twinning in two of the three crystallographic orientations studied, and transmission electron microscopy results revealed the existence of dense dislocation walls (sheets) along crystallographic ...
متن کاملStrain hardening in polymer glasses: limitations of network models.
Simulations are used to examine the microscopic origins of strain hardening in polymer glasses. While traditional entropic network models can be fit to the total stress, their underlying assumptions are inconsistent with simulation results. There is a substantial energetic contribution to the stress that rises rapidly as segments between entanglements are pulled taut. The thermal component of s...
متن کاملSolid-State Diffusion Bonding of Commercially pure Titanium and Precipitation Hardening Stainless steel
Solid-state direct diffusion bonding of commercially pure Titanium (Cp-Ti) and precipitation hardening stainless steel (PHSS) has been carried out in the temperature range of 800°C to 1000°C with an interval of 50°C for 3.6 ks under 3.5 Mpa uniaxial load in (4 to 6)×10 Pa vacuum. The effects of temperatures have been investigated with reference to bond strength. The examination revealed that th...
متن کاملStrain Hardening of Fractal Colloidal Gels
We report on experiments on the rheology of gels formed by diffusion-limited aggregation of neutrally buoyant colloidal particles. These gels form very weak solids, with the elastic modulus, G0svd, larger than the loss modulus, G00svd, and with both G0svd and G00svd exhibiting only a very weak frequency dependence. Upon small but finite strains g , 0.45 the elastic modulus increases roughly exp...
