Measurement Of Average Grain Size Of Metals

Applicable materials: Suitable for various metals and alloy materials such as steel, cast iron, copper and copper alloys, aluminum and aluminum alloys, titanium and titanium alloys, nickel based alloys, etc.

Applicable products: including plates, bars, profiles, pipes, wires, forgings, castings, welded joints, and various mechanical components.

Applicable states: including as cast, hot-rolled, cold-rolled, annealed, normalized, quenched and tempered, solid solution, aging and other heat treatment and processing states.

Purpose of Inspection: Used for material acceptance, heat treatment process evaluation, mechanical property verification, quality control, and failure analysis.

Average grain size determination: Determine the average grain size level of the metal material matrix.

Grain uniformity assessment: Check the uniformity of grain size and determine whether there are mixed grains, coarse grains, or fine grains.

Observation of grain morphology: Observe grain shape, grain boundary characteristics, deformation, and recrystallization microstructure.

Grain size grading: The grain size is graded and evaluated according to the standard spectrum method or cut-off point method.

Abnormal organization inspection: Identify abnormal organizations that affect grain size, such as overburning, overheating, and incomplete recrystallization.
