Castability. Castability is the ease of forming a quality casting. [ 1] A very castable part design is easily developed, incurs minimal tooling costs, requires minimal energy, and has few rejections. [ 2] Castability can refer to a part design or a material property. [ 1]
Explosive materials are produced in numerous physical forms for their use in mining, engineering, or military applications. The different physical forms and fabrication methods are grouped together in several use forms of explosives . Explosives are sometimes used in their pure forms, but most common applications transform or modify them.
In heat transfer, the thermal conductivity of a substance, k, is an intensive property that indicates its ability to conduct heat. For most materials, the amount of heat conducted varies (usually non-linearly) with temperature. [ 1] Thermal conductivity is often measured with laser flash analysis. Alternative measurements are also established.
Refractoriness. [edit] Refractoriness is the property of a refractory's multiphase to reach a specific softening degree at high temperature without load, and is measured with a pyrometric coneequivalent (PCE) test. Refractories are classified as:[2] Super duty:PCE value of 33–38. High duty:PCE value of 30–33.
Refractory metals. Refractory metals are a class of metals that are extraordinarily resistant to heat and wear. The expression is mostly used in the context of materials science, metallurgy and engineering. The definition of which elements belong to this group differs. The most common definition includes five elements: two of the fifth period ...
Continuous casting, also called strand casting, is the process whereby molten metal is solidified into a "semifinished" billet, bloom, or slab for subsequent rolling in the finishing mills. Prior to the introduction of continuous casting in the 1950s, steel was poured into stationary molds to form ingots. Since then, "continuous casting" has ...
Steel castings are used when iron castings cannot deliver enough strength or shock resistance. [1] Examples of items that are steel castings include: hydroelectric turbine wheels, forging presses, gears, railroad truck frames, valve bodies, pump casings, mining machinery, marine equipment, turbocharger turbines and engine cylinder blocks. [1]
Where x is the material type (only 1 is specified so far), yy is the steel group number (specified in EN10027-2) and zz(zz) is a sequential number designated by the certifying body, the number in brackets being unused but reserved for later use.
