Case Depth Measurement by Cross-Section and Hardness Traverse
Case depth measurement methods — destructive cross-section hardness traverse, effective vs. total case depth, microhardness methods, and documentation for induction-hardened parts.
Effective Case Depth vs. Total Case Depth: Definitions and Specification
Effective case depth and total case depth defined per SAE J423 and ISO 2639, with drawing callout examples and measurement standards for specification.
Microhardness Indentation for Case Depth Profiling (ASTM E384 Procedure)
ASTM E384 microhardness for case depth profiling — Vickers/Knoop indent loads, spacing, traverse protocol, and effective case depth interpolation.
