acicular ferriteの例文

• Acicular ferrite is also characterised by high angle boundaries between the ferrite grains.
• Acicular ferrite is a fine cleavage.
• Composition control of weld metal is often performed to maximise the volume fraction of acicular ferrite due to the toughness it imparts.
• In steel it produces a bainite microstructure whereas in cast irons it produces a structure of acicular ferrite and high carbon, stabilized austenite known as " ausferrite ".
• Acicular ferrite is formed in the interior of the original austenitic grains by direct nucleation on the inclusions, resulting in randomly oriented short ferrite needles with a'basket weave'appearance.
• Some confusion has arisen in the literature, as this fine-scale intragranular bainite, which can resemble acicular ferrite in appearance in the optical microscope, has been called acicular ferrite by some researchers.
• Some confusion has arisen in the literature, as this fine-scale intragranular bainite, which can resemble acicular ferrite in appearance in the optical microscope, has been called acicular ferrite by some researchers.
• In C-Mn steel weld metals, it is reported that nucleation of various ferrite morphologies is aided by non-metallic inclusion; in particular oxygen-rich inclusions of a certain type and size are associated with the intragranular nucleation of acicular ferrite, as observed, for example, by,.
