Compare Casting vs. Forging - Iron foundry

The tight grain structure offers great wear resistance without the need to make products "super hard" We have found that, on a blank HRC 38-42 forged grinder insert wear/wash is about the same as a high alloy HRC 46-50 cast grinder insert.

Particle Size Conversion Table | Sigma-Aldrich

Large sieve openings (1 in. to 1/4 in.) have been designated by a sieve "mesh" size that corresponds to the size of the opening in inches. Small sieve "mesh" sizes of 3 1/2 to 400 are designated by the number of openings per linear inch in the sieve. The following convention is used to characterize particle size by mesh designation:

Dimensional modeling: Identify the grain - IBM

When you identify the grain, you specify exactly what a fact table record contains. The grain conveys the level of detail that is associated with the fact table measurements. When you identify the grain, you also decide on the level of detail you want to make available in the dimensional model.

Grain Size | Fisk Alloy

Grain directionality occurs when metal is cold worked in one direction between anneals. Directionality (Good Way Bends) can be minimized by fine grain size. Formability; Grain boundaries impede plastic flow. The larger the grain size, the fewer the grain boundaries and the greater the potential for deformation. Surface Appearance

Industrial: Design Guide - Grain Size - Copper

The grain size of a metal or single phase alloy is an estimate of the average grain diameter, usually expressed in millimeters. The metallurgical techniques used to determine grain size are not necessary for this discussion, the major point to remember is that grain size is an important material characteristic.

Strengthening mechanisms of materials - Wikipedia

The stress required to move a dislocation from one grain to another in order to plastically deform a material depends on the grain size. The average number of dislocations per grain decreases with average grain size (see Figure 3). A lower number of dislocations per grain results in a lower dislocation 'pressure' building up at grain boundaries.

Sand Casting | Metal Casting Resources

Sand casting is a process that utilizes non-reusable sand molds to form metal castings.It is a common production method for metal components of all sizes, from a few ounces to several tons. Sand casting isn't only versatile in the size of its products – it can also create exceptionally complex or detailed castings, and can be used to cast nearly any metal alloy.

ABRASIVE PRODUCTS CATALOGUE - grindtech

The block shaped crude abrasives are reduced to abrasive grain size by crushing and milling. The abrasive grains are then graded, the range of sizes being internationally standardised according to the sieve mesh size. The grain numeral gives the number of meshes per linear inch. Very fine grains (micro grains) are obtained by sifting and ...
