As a result of calculations it was stated that after undercooling ductile iron below liquidus temperature volumetric changes proceed in three stages: preeutectic shrinkage (minimal in eutectic cast iron), eutectic expansion (maximum value equals to about 1.5% for ES = 1.05) and last shrinkage (...
Since steel is an iron-carbon alloy, then steel that is made from alpha-iron is a low-carbon steel. This type of steel is ductile (the shape can be manipulated) and is used in wires. Alpha iron contains the highest volume and is the least dense of the three atmospheric allotropes. ...
Density-enhanced compositions that are comprised of at least iron and tungsten, and articles, including firearm projectiles, formed therefrom. The articles have a density that exceeds that of steel, and which may be less than, equal to, or greater than that of lead. In some embodiments, iron...
for use as armor piercing penetrators and the like, the alloy having high mechanical strength and yet being sufficiently ductile so as not to fracture or fragment upon impact with enemy targets, and preferably comprising about 97.0 weight % tungsten, and 1.5 weight % each of nickel and iron....
The density of a series of five different iron-cobalt alloys was measured using electrostatic levitator processing. Each sample was processed through multiple thermal cycles and the liquid density was measured, while the superheated sample was cooled down to its undercooled state. The volume of the ...

High strength austempered ductile iron (ADI) gears are widely used in mechanical transmissions having as main advantages the low production cost, the eventual noise and vibration reduction and the self lubricant properties of graphite no... R Martins,J Seabra,L. Magalhes,... 被引量: 2发表: ...
Lower may mean that the material grade has not reached to this grade, and higher hardness may cause the difficulty and low speed of machining. So, normally, iron foundries should produce this grade of ductile iron castings in this range. The hardness could be adjusted by chemical composition....
