Constraint and Ductile Tearing Effects on the Cleavage Fracture of Ferritic Steel
… characterize the ductile-tobrittle toughness of ferritic steels in terms of KJc (or Jc) values with the Weibull stress model, i.e ., the ""local approach"" for fracture at the micro-scale. The E1921 procedures assume that uniform, small-scale yielding (SSY) conditions exist at fracture along the …

The effect of nickel addition by diffusion on the microstructure of AISI 304 austenitic stainless steel and S.A. 212 ferritic steel
Diffusion couples between nickel and S.A. 212 ferritic steel and between nickel and AISI 304 austenitic stainless steel were studied to determine the effect of nickel on the structure of these steels after diffusion anneals at 1300 ℉. Diffusion times varied from 50 to 4000 hours. The migration of …

Effect of titanium pick-up on mould flux viscosity in continuous casting of titanium-stabilised stainless steel
… casting of two Ti-stabilised stainless steels was investigated in terms of the level of titanium pick-up by the flux and the effect of this absorption of titanium on the viscosity of the fluxes. The two fluxes considered are respectively used for the casting of a ferritic steel (type …

The effect of drawing strain on the fatigue behaviour of stainless and carbon steel wires
… crack growth behaviour of three different steels in wire form, namely, an austenitic AISI 304 stainless steel, a corrosion resistant ferritic steel, 3CR12, and pearlitic high carbon steel. The stainless steel wires were produced in the laboratory at a drawing speed of 50 mm min-1, without …

Abrasive wear resistance of ruthenium aluminide intermetallic and ferritic steels containing a sigma intermetallic phase
… of ruthenium aluminide intermetallic and ferritic steel containing an iron-chrome sigma intermetallic phase have been investigated in this study. A medium carbon wear resistant steel (MCV) was used in the study to facilitate comparison between wear resistances in the materials of interest. …

A microstructural examination of duplex ferrite -martensite corrosion resisting steels
… of chromium containing duplex ferrite-martensite steels and examines the effects of the microstructure on the mechanical properties. Emphasis has been placed on determining the microstructural factors responsible for the persistent occurrence of anisotropy in a modified 12 wt% Cr steel designated …
