Cast irons include many metals having a wide variety of properties. Although cast iron is often considered a simple metal to produce and to specify, the metallurgy of cast iron is more complex ...
Blast cleaning is the removal of rust and mill scale by the use of compressed air to project a high velocity stream of abrasive such as aluminium oxide, garnet, grit or steel shot onto the metal surface.
to the base metal, hardness, corrosion resistance, and thickness (Figure 2) of each zinc coating varies. This practical aid examines the following zinc coatings: batch hot-dip galvanizing, continuous sheet galvanizing, zinc painting, zinc spray metallizing, mechanical plating, electrogalvanizing, and zinc plating; to help architects,
Metal Machining The term "machinability" is a relative measure of how easily a material can be machined when compared to 160 Brinell AISI B 1112 free machining low carbon steel. The American Iron and Steel Institute (AISI) ran turning tests of this material at 180 surface feet and compared their results for B 1112 against several other materials.
Planetary mill: High energy mill widely used for producing metal, alloy, and composite powders. Fluid energy grinding or Jet milling: The basic principle of fluid energy mill is to induce particles to collide against each other at high velocity, causing them to fracture into fine particles.
Ball milling is a mechanical process and thus all the structural and chemical changes are produced by mechanical energy. I have seen an interesting image at for ball milling method at wikipedia . You can see the image here .
Increasing milling loads augmented the probability to create micrometer-sized particles. Lower milling rates increased plastic deformation processes and particle agglomeration mechanics during the milling process. Fabricated iron nanoparticles were used to synthesis bulk specimens by a cold and subsequent warm consolidation process.
5.1 This practice is to be used for sampling and sample preparation of iron ores and related materials, prior to use of a referee method for testing for compliance with compositional specifications for metal content or physical properties.

Pure iron is a soft, grayish-white metal. Although iron is a common element, pure iron is almost never found in nature. The only pure iron known to exist naturally comes from fallen meteorites. Most iron is found in minerals formed by the combination of iron with other elements. Iron …
Iron powders were prepared using mechanical milling on the Fritsch P-6 planetary ball mill, with milling times in the range of 1–30 h. The iron powders obtained have the following typical characteristics: Morphology, crystal structure, particle size, porosity and saturation magnetization, coercivity change over milling time.

Mechanical alloying (MA) is a solid-state and powder processing technique involving repeated cold welding, fracturing, and re-welding of blended powder particles in a high-energy ball mill to produce a homogeneous material.
C Steel surface on which the mill scale has rusted away or from which it can be scraped, but with little pitting visible to the naked eye. D Steel surface on which the mill scale has rusted away and on which considerable pitting is visible to the naked eye. Preparation grades. Scraping and wire-brushing
Casting offers exceptional capacity for design detail, often eliminating the need for additional fabrication and assembly. Many materials can be cast, including several types of metals and synthetics, but iron and steel in particular feature excellent mechanical properties for a wide range of applications.
