; nucleation mechanism; second phase 铝合金热轧的显微组织由热轧时及热轧间隔过程中的回复与再结晶所决定,并对热... compression in which the main nucleation mechanisms are strain induced grain boundary migration(SIBM) and sub-grain coalescence and growth. The migration of grain and sub-grain boundaries can be retarded......
and comprehend the grain refinement mechanism [16]. In general, effective heterogeneous nucleation sites need to achieve the maximum atomic matching between particle and matrix across the interface. To meet... as the heterogeneous nucleation sites for dynamic recrystallization during the extrusion due to the crystallography matching relationship. Extrusion deformation leads to dynamic recrystallization, which results......

Mechanism and Influence Factors of V6O13 Synthesis林勤,杜垣胜,叶文,刘康,刘人敏,李晓云摘 要:<正> The mechanism and influence factors of thermal decomposition of NH4VO3... by a first order reaction or nucleation and nucleigrowth with a kinetic equation--ln(l-a)=kt,and apparent activation energy of 410kJ/molis obtained.关键词:......
was used as an interlayer on the steel substrates by high velocity oxy-fuel spraying. The effects of methane content on nucleation, quality, residual stress and adhesion of diamond films were investigated. The results indicate that the increasing methane content leads to the increase in nucleation density, residual stress, the degradation of quality and adhesion of diamond films. Diamond films......

that the nucleation density of diamond on the Ni-modified Cu substrates is 10 times higher than that on blank Cu substrates. The enhancement mechanism of the nucleation kinetics by Ni modification layer results.... HAN et al [12] adopted graphite seeding and CO2 laser irradiation to enhance diamond nucleation on Cu substrate. The enhancement mechanism is attributed to the formation of defects and edges during......
