Abstract Several time-compensated temperature parameters, which were proposed as dependent only on the initial stress, are discussed with relation to time of creep rupture and minimum average rates. The so-called master “curve” is in terms experimentally determined relationships. In checking validity using experimental results for several ferritic austenitic steels, it found that these parameters not single-valued functions stress over wide ranges existence a curve doubtful.
We report magnetotransport measurements of InSb/Al1-xInxSb modulation doped quantum well (QW) structures and the extracted transport lifetime carriers at low temperature consider conventional lifetimes over a range samples with different doping levels carrier densities, deduce regimes dependent on QW state filling calculated from self-consistent Schrödinger–Poisson modelling. For where only lowest subband is occupied electron densities cm−2 ps, ps are Shubnikov–de Haas oscillations below...

Cold working of metals affects the mechanical properties those metals. These effects are particularly important in design, analysis and subsequent performance materials used elevated temperature nuclear construction. This paper provides an assessment cold on time independent dependent most commonly encountered liquid metal fast breeder reactors. The suggests specific reductions, as a function time, work level, for adversely affected. final objective this is to provide manner which Code now...
