Microstructure and texture development in AISI430 ferritic stainless steel
… influences the microstructure evolution and texture development during hot rolling and subsequent annealing heat treatments. Two AISI 430 FSS heats of varying austenite volume fraction were used in this study. The two AISI 430 FSS heats were deformed using the first three passes of the …

Microstructure and texture development during high-strain torsion of NiAl
… figure is needed in order to obtain the complete texture information, which is more than is needed e.g. by extrusion or rolling. Therefore, texture analysis might be more sensitive with respect to texture components. Furthermore, torsion deformation is characterized by being inhomogeneous in terms …

"Studies of ""Reactive Templated Grain Growth"" in Some Complex -Oxide Perovskites"
Formulation affected the microstructure and texture development in the RTGG-processed BNKT. Pre-reacting the alkali carbonates and TiO2 (to Na2Ti3O7 and K2Ti2O 5) inhibited texture development. No such effect was observed when Bi 2O3 and TiO2 were pre-reacted to Bi2Ti 4O11, instead the measured …

Stochastic Mean-Field Polycrystal Plasticity Methods
… specimens. Our simulation predictions mimic the texture and deformation data measured from a powder metallurgy specimen. However, round-corner square rolled (RCSR) specimen simulations over-predict the texture development and do not accurately predict the specimen deformation. We attribute this …

Microstructural evolution of sputtered phase segregated metal composite thin films
… the first comparative study of crystallographic texture development in three different types of metal thin film composites: fully miscible (Au-Ag), slightly immiscible (Cu-Ag) and immiscible (Au-SiO 2). Texture development refers to the distribution of orientations of crystallites in …

Phase development and texture for lead-based perovskite thin layers prepared by sol-gel processing
The evolution of phases and the development of texture were investigated for sol-gel derived lead-based perovskite thin layers. Dielectric and ferroelectric properties were examined in terms of crystal structure, microstructure, and preferred orientation. Ferroelectric La-modified Pb(Zr,Ti)O$\sb3$ …
