Microscopic Examination of Metals

Material failure always has its roots at the microscopic level, where tiny interactions between grains ultimately establish the macro-level performance. These interactions are evident during microscopic examination of metals, where the aggregate work of manufacturing processes creates defects at the surface that can result in reduced performance or failure. For this reason, microscopic examination is necessary for any metal characterization, as it provides a detailed detection of present microstructures.

Microscopic Examination of Metals

During microstructure analysis of metals and alloys, a microscopic examination studies the microstructural features of the material under magnification. These microstructure analyses range from simple grain size or coating thickness determination to thoroughly evaluating abnormalities and failure mechanisms such as inclusions, segregation, and surface layers.

Microscopic analysis performed at LTI is Nadcap and A2LA ISO/IEC 17025 accredited. Examinations are completed according to detailed procedures and applicable industry standards to ensure reliability. A detailed microstructure analysis lab report is available when testing is complete.

LTI’s Material Lab Testing Is an Industry-Leader

Microscopic examination of metals reveals a world of microstructure defects hidden from the naked eye. By detecting these surface abnormalities, our experienced Metallurgists can propose remediation steps to correct their presence and prevent them from occurring in future material samples or products. For proper material characterization, labs need expertise and equipment for thorough analysis. Fortunately, LTI excels in both – our whole model is built around providing customers with all their material testing needs in a single location to simplify logistics and approvals.

I would like to thank you and the associated departments at LTI that have helped delivered these reports in a short turnaround time. Our customer appreciates it.
