Thermomechanical processing of advanced high strength steels ...

Advanced high strength steels (AHSSs) are regarded as the most promising materials for vehicles in the 21st century. AHSSs are complex and sophisticated materials, with microstructures being controlled by precise thermomechanical processing (TMP) technologies.

Blade Steels, Steel Analysis and Heat Treating Methods.- 1st page

AEBL. Seems to be about the same as 440-B.Extremely easy to grind, heat treats like 440-C. Very easy to buff and polish, but is reported to have 'several quirky' habits in grinding that makes it difficult to use on larger or thicker knives.

JIS G 3141 Commercial Cold Rolled SPCC Steels - Material Grades

Cast Steels and Steel Castings |

Cast Steels and Steel Castings. Steel casting is a specialized form of casting involving various types of steels. Steel castings are used when cast irons cannot deliver enough strength or shock resistance.

Magnesium alloy - Wikipedia

Magnesium alloys are mixtures of magnesium with other metals (called an alloy), often aluminum, zinc, manganese, silicon, copper, rare earths and zirconium.Magnesium is the lightest structural metal.

The Key Role of Impurities in Ancient Damascus Steel Blades

Sword 8 is hypoeutectoid and, therefore, cannot be a true wootz Damascus steel, because such steels will not form Fe 3 C particles on cooling. Metallographic examination confirmed this expectation and revealed that the surface pattern seen on this sword (Figure 2) was due to ferrite bands in a pearlite matrix.

High-speed steel - Wikipedia

High-speed steel (HSS or HS) is a subset of tool steels, commonly used as cutting tool material.. It is often used in power-saw blades and drill bits.It is superior to the older high-carbon steel tools used extensively through the 1940s in that it can withstand higher temperatures without losing its temper (hardness).

EN25 High Tensile Steel | Interlloy | Engineering Steels + Alloys

Heat Treatment: Annealing: Heat to 800 o C - 850 o C, hold until temperature is uniform throughout the section and cool in furnace. Flame or Induction Hardening: EN25 hardened and tempered bar can be further surface hardened by either the flame or induction hardening methods resulting in a case hardness of Rc 50 approx. Parts should be heated ...
