conductivity of magnesium alloy itself, which caused that the grain growth was suppressed by rapid welding rate and cooling rate during the welding process. Fig. 1 Microstructures of AZ31B magnesium alloy... to heat generation at a greater rate than heat loss from the specimen by conduction, convection and radiation. Along with the rapid increase of temperature, large cyclic hardening effect appears......
, PREP is a rapid cooling process and therefore the high temperature phases can be retained to room temperature. The cooling rate in each individual particle is different, depending on its particle size... disintegrated into smaller ones, which are solidify into the so-called "secondary particles". Due to surface tension during rapid solidification, spherical or spheroid particles are formed......
solid forming uses a focused laser heat source [4-6] to fabricate component layer-by-layer with rapid cooling and solidification. It can achieve near-net-shape components with excellent performance... the cooling rate (G·R) plays an important role to discuss the dendritic microstructure and microscopic segregation [26, 27]. Due to the rapid cooling in the molten pool and solute redistribution during......
was approximately 107 cells/mL) in 18 bottles. Consortium C was inoculated with L. ferriphilum YSK during the period of rapid growth of indigenous microbial community (at 66 h) in 12 bottles. Consortium... by approximately 19%. The rapid oxidation of pyrite produced a large amount of Fe2+ after the growth period, while the iron-oxidizing bacteria L. ferriphilum YSK grew faster due to the increase in energy......
a unique dislocation-free deformation mechanism, and thus its recovery and recrystallization behavior should be further studied and compared with traditional BCC metals. The substructures of the cold-swaged and the annealed TNTZO alloy were investigated by transmission electron microscopy(TEM) to study the recovery of the cold-swaged TNTZO alloy. The results show that no dislocation can......
