Austenitization and Tempering Temperatures Effects on EUROFER 97 Steel
Materials Science Forum, 2018EUROFER 97 is considered as standard steel for the nuclear applications in the case of high radiation density for first wall of a fast breeder reactors. Based on such consideration the microstructural behaviour of EUROFER 97 after thermo-mechanical processing is fundamental, since such materials properties are interesting also for innovative solar ...

Instead of conventional quenching and tempering, fast austenitization from an initial microstructure of lamellar pearlite followed by quenching and tempering was carried out, leading to the formation of inhomogeneous microstructure. It comprised different morphologies of lath martensite and retained austenite (RA).

Temperate Drosophila preserve cardiac function at low temperature
Journal of Insect Physiology, 2015Most insects are chill susceptible and will enter a coma if exposed to sufficiently low temperature. This chill coma has been associated with a failure of the neuromuscular system. Insect heart rate (HR) is determined by intrinsic regulation (muscle pacemaker) with extrinsic (nervous and humoral) input. By examining the continually active heart of five

Modeling temperature in chocolate mass to predict tempering quality
European Journal of Lipid Science and Technology, 2009AbstractA computational model is developed to predict the temperature in chocolate as a function of space and time during a new tempering process where pellets of seed crystals of form V are added to the melted chocolate. The model, a refined version of a previous one (Debaste et al., J Food Eng.

40Cr steel is categorized as quenched-tempered steels and is widely used in gears, bolts, couplings, spindles, etc. To study the plastic deformation behaviour of the steel after quenching and tempering, compression and double-pass compression tests have been carried out.

Nutrient and Temperature Limitation of Bacterioplankton Growth in Temperate Lakes
Microbial Ecology, 2005Limitation of bacterioplankton production by nutrients and temperature was investigated in eight temperate lakes in summer. Six of the lakes were resampled in autumn. The lakes differ in nutrient content, water color, and concentration of dissolved organic carbon. Nutrients (phosphorus, nitrogen, and organic carbon) were added alone and in all possible

Temperature Responses and Yield in Temperate Crops
1979Assuming that mineral nutrients and water supply are not limiting, crop yield depends upon: (1) the photosynthetic rate, (2) the amount of solar radiation intercepted and utilized in photosynthesis over the growing period, and (3) the proportion of total dry matter constituting the harvested part of the plant (harvest index).

Afforestation and stream temperature in a temperate maritime environment
Hydrological Processes, 2006There have been few long term investigations of the effects of afforestation on stream temperatures in the UK, and the present study uses the results of continuous monitoring of water temperatures in a forest and a moorland stream of the Loch Grannoch area in southwest Scotland over a 4 year period to investigate the effects of planting coniferous ...

Effect of Tempering Temperature on Abrasinite-500 [PDF]
, 2017 This thesis investigates the effect of various tempering temperature on Abrasinite 500 with a bainitic morphology. This was achieved by performing heat treatment, hardness test, Charpy impact test and analysis the microstructure of the steel. While the tempering temperatures used in this thesis belonged to the lower range of tempering temperatures, it ...
