Characterisation of microstructure, defect and high-cycle-fatigue behaviour in a stainless steel joint processed by brazing [PDF]
, 2019 We report the characterisation of microstructures and high-cycle-fatigue (HCF) properties of Type 304 stainless steel joints processed by brazing. Pure copper was applied as the filler metal for brazing at 1120 °C. A two-phase microstructure was obtained

Growth response to temperature of two maize (Zea mays L.) hybrids with differing levels of cold tolerance : a thesis presented in partial fulfillment of the requirements for the degree of Master of Agricultural Science in Plant Science (Seed Technology), Massey University [PDF]
, 1993 Low temperatures are a hazard to maize production especially in high altitude and high latitude areas (Eagles, 1979; Hardacre and Eagles, 1986) where it may cause substantial yield reductions through its accumulated effect on vegetative and reprodutive ...

Effect of Initial Grain Size on Dynamically Recrystallized Grain Size in AZ31 Magnesium Alloy
MATERIALS TRANSACTIONS, 2008 The effect of initial grain size on dynamically recrystallized grain size (DRX grain size) is examined in AZ31 magnesium alloy with four kinds of initial grain sizes. When the average grain size after the high-temperature compression test is plotted against Zenner-Hollomon parameter (Z-parameter), initial grain size dependence on DRX grain size appears
