Sentence examples for grain reduction from inspiring English sources

Chlorite precipitation and grain reduction in cataclasite (and ultracataclasite) would reduce permeability acting as a barrier for fluid flow.

Grain reduction and the rate of grain refinement as a function of the processing conditions of constrained groove pressing (CGP) for a Cu 38Zn alloy is investigated.

With these modifications and assuming that grain size is in a quasi-steady state, equation (12) becomes (13 where (14)are the nondimensional coefficient of grain reduction and grain growth, respectively.

The present model uses an activation energy for grain boundary mobility of 350 kJ and for dislocation creep of 520 kJ; therefore the derivative of grain growth rate with respect to temperature is always greater than that of grain reduction.

This means that as a first approximation, the reduction in grain growth rate due to a secondary mineral phase with uniform distribution in space is captured by increasing p. The coupling between both grain reduction and growth rates through the mean grain size leads to an increase in mean grain size only for those regions where grain growth rate dominates.

Multipass friction stir processing of AA 2219-T87 alloynium alloy to a depth of 2 mm in a 5 mm plate resulted in fine α-Al grains, reduction and dissolution of both eutectic phase (CuAl2) and the strengthening precipitates (CuAl2).

Never ripe pollen grains exhibited higher heat-stress sensitivity, manifested by a significant reduction in the total number of pollen grains, reduction in the number of viable pollen and elevation of the number of non-viable pollen, compared with wild-type plants.

The grain growth and reduction parameters are dimensionless numbers formed by taking the ratio of grain-growth and grain-reduction prefactors to the characteristic scale associated with grain-size advection.

A few other studies also show that the flow stress of ultrafine nano-structured materials can decrease as a result of grain size reduction.

The highly attenuated lower crust observed beneath the NKTZ west of the ISTL is probably affected by grain size reduction due to localized, high-strain-rate deformation, because grain size reduction enhances seismic attenuation (Jackson et al. 2002).

The strong increase in the microhardness in the temperature regime of defect recovery leading to grain size reduction can be explained either by a Hall Petch mechanism or by hardening due to the reduction in dislocation sources.
