Investigating the influence of thermomechanical variables on ridging in aisi 430 stainless steel
The phenomenon of ridging is known to occur in most ferritic stainless steels and is manifested during deformation of sheet material. It results in the formation of a corrugated profile with ridges always elongated in the rolling direction of the sheet and are typically around 1 mm in wavelength. …

Resurrecting the martyrs: the role of the Cult of the Saints, A.D. 370-430
… Chrysostom (d. 407), and Augustine of Hippo (d. 430). Though contemporary with one another, these three men all viewed the cult of the martyrs as fulfilling somewhat different needs for their congregations. The last chapter describes the controversy over the cult in Gaul, where some clergy …

Design of a 405/430 kHz, 100 kW Transformer with Medium Voltage Insulation Sheets
To achieve higher power density, converters and components must be able to handle higher voltage and current ratings at higher percentages of efficiency while also maintaining low cost and a compact footprint. To meet such demands, medium-voltage resonant converters have been favored by researchers …

Microstructure and texture development in AISI430 ferritic stainless steel
AISI 430 ferritic stainless steel (FSS) is the most widely used FSS alloy due to good resistance to stress corrosion cracking. Owing to the chemical composition range, AISI 430 alloys undergo a partial phase transformation of ferrite to austenite when subjected to hot rolling temperatures. …
