Electrochemical behaviour of hot and cold rolled HSLA steelsdoi:10.1016/0390-6035(82)90094-3Surface modifications induced by rolling temperature on various HSLA steels are investigated. The main effect of the temperature is the formation of a surface oxide barreer and the diffusion of carbon towards...
Of the features investigated, strain hardening characteristics of the material were identified as being primarily responsible for the differences in structural behaviour between hot-rolled and cold-formed sections. 展开 关键词: bending cold-formed sections continuous beams corner geometry geometric ...
Some records are "hot" and accessed frequently (the work- ing set), others are "cold" and accessed infrequently, while "lukewarm" records lie somewhere in between. Clearly, good performance depends on the hot records residing in memory. Cold records can be moved to cheaper external storage ...
Objective It is to study the cold or hot constitution in four species of mice. Methods Simultaneous systematic inspection about biological characteristics of eight to nine week-old Kunming mice, BALB/c mice, C57BL/6Jmice and ICR mice and four to five week-old Kunming mice were taken, and th...
To examine the subtle coordination between thermoregulatory behaviours, and to test if inhibiting gaping would lead to thermoregulatory compensatory behaviours, bearded dragon lizards (Pogona vitticeps) were allowed to behaviourally thermoregulate, while their ability to show spontaneous gaping behaviour was...
The influence of hot strip coiling temperature on microstructural characteristics, mechanical properties and hydrogen permeation behaviour of boron contain... G Papp,D Geyer,G Giedenbacher 被引量: 38发表: 1990年 Deep-drawing quality of cold rolled sheet made of ferritically rolled hot strip In the...
and high temperature behaviour of Yfh1 in the presence of PEG must be sought in the indirect effect on water activity. The ability of PEG polymers to lower water activity is routinely exploited in protein crystallization39,40. Its asymmetric effect on cold and hot denaturation is consistent with...
Fig. 5: Calculated resistance under non-equilibrium for gapped and ungapped graphene. aCalculated variation of resistance as a function of average electric field for monolayer graphene (atμ = 30 meV). Calculations are performed assuming cold phonons and various values of the electron–phonon...
