Metallographic Evaluation & Metallurgical Analysis
Hurst Metallurgical Research Laboratory provides comprehensive metallographic evaluation services to characterize the microstructure and condition of metallic materials. Using precision specimen preparation and optical microscopy, our experienced metallurgists evaluate microstructural features that influence material performance, manufacturing quality, heat treatment, and failure mechanisms.
What is Metallographic Evaluation?
Metallography is the study of a material's internal structure using carefully prepared specimens and microscopic examination. By evaluating the microstructure, our metallurgists can identify manufacturing conditions, heat treatment response, material quality, and evidence of degradation or failure.
Metallographic evaluation is frequently used to verify specification compliance, investigate failures, troubleshoot manufacturing issues, and support product development.
