experiments were carried out in which the dependence of the fractional softening on temperature, time and strain rate was determined in a 304h stainless steel. three prestrain ranges were identified pertaining to three different post-deformation softening behaviors: 1) prestraining to below the drx critical strain: strongly strain dependent softening by srx alone with softening kinetics control...

In the range 16 to 29 degrees C, increases in temperature caused large (two-to threefold) increases in growth velocity, growth strain rate, and biomass deposition rate in primary roots of maize, Zea mays L. Temperature had small effects on root diameter, fresh weight density, and dry weight density, and negligible effects on length of the growth zone and growth strain at particular positions.

processing map for hot working of ti-if steel has been developed in the temperature range of 750 to 1100 °cand strain rate of 0.01 to 100 s-1. this map in the austenite region exhibits a single domain with a peak efficiencyof 45% occurring at 1025 °c and strain rate of 0.02 s-1. the domain extends over the temperature range of 1000to 1100 °c and strain rate range of 0.01 to 1 s-1. the true stre...

In industrial rolling, changes in strain rate and temperature occur with strain during passes, and between one pass and the next. Plane strain compression testing has been used with ramped changes in strain rate during deformation, and with changes in strain rate between two deformations to study their effects on flow stress. No systematic deviations from a mechanical equation of state were fou...

strain induced precipitation in hsla-100 steel was investigated by conducting hotcompression and relaxation tests at temperature range of 850°c to 1100°c and strain rate of 0.001s-1 to 1s-1. the absence of dynamic recrystallization at temperatures below 1000°c was attributedto the influence of dynamic precipitation. the stress relaxation tests showed that strain inducedprecipitation is possible...

Seed priming, as a low-cost method, is a technique commonly used to increase germination percentage especially under unfavorable conditions. The objective of this study was to evaluate the effects of bio-priming on the germination of canola (Brassica napus L.) seeds under saline (NaCl) conditions. Seeds of canola var. Hyola 401 were inoculated with plant growth-promoting microorganism (PGPM) in...
