Sample preparation
Specimen Preparation
Cutting, grinding, and finishing steps that produce test pieces with required geometry, surface integrity, and alignment before mechanical, impact, or microstructural testing.
What it measures
Specimen preparation is not a measured property—it is the workflow that ensures test results reflect material behaviour rather than machining damage, wrong dimensions, or misaligned notches.
How it is tested
Routes include crushing and milling for bulk sampling, machining for tensile rounds and Charpy bars, and grinding/polishing for metallographic or hardness mounts.
Standards and reporting
Each downstream test (tensile, Charpy, hardness) references allowable preparation in its standard. Document heat-affected zones, coolant, and final dimensions on the test report chain.
Common errors
Overheating during cutting, incorrect notch root radius, and out-of-tolerance gauge lengths are leading causes of rejected mechanical tests.

Grinding and Polishing
Sequential abrasive steps from coarse SiC paper through diamond suspensions to remove deformation and achieve a scratch-free surface for optical etching and microscopy.
-
Metallographic Mounting
Encapsulating a specimen in resin (hot compression or cold pour) to support edges, retain fragile features, and produce a flat surface for grinding and polishing.

Charpy Impact Test
A notched bar is broken by a swinging pendulum striker; absorbed energy KV or KU (joules) characterizes toughness and ductile-to-brittle transition versus temperature.
