Fatigue Failure Analysis

Fatigue failure analysis investigates material and/or component failure to identify the underlying cause based on cyclic load performance under actual operating circumstances.

The highly skilled engineers at Infinita Lab develop test plans and computer simulations while doing different kinds of fatigue failure analysis. Functional cycle testing on real components or conventional ASTM techniques can both be used for this. As a full-service materials testing, analytical, and component testing lab, Infinita Lab focuses on the physical and chemical behavior of a variety of materials, including but not limited to titanium, ceramics, plastics, steel, stainless steel, superalloys, copper alloys, aluminum, and steel and copper alloys. The metallurgists and technicians at Infinita Lab carry out hardness and tensile testing, chemical analysis, metallography, scanning electron microscopy (SEM), energy dispersive spectroscopy (EDS), visual inspection, and optical fractography using cutting-edge equipment. Also, the fundamental causes of numerous additional material-related concerns, including overload fractures, cracking, formability problems, microstructural deterioration, corrosion, and wear, are determined in our fatigue failure analysis lab.

Material identification is a crucial component of fatigue failure analysis. The process of figuring out the chemical composition of different metals is known as alloy identification. Alloys are composed of two or more metals and are typically combined to increase strength or resistance to corrosion. The amalgam that makes up the alloy is meticulously identified during the alloy identification process. Scanning electron microscopy (SEM), which generates stunning images of surfaces at varying powers of magnification up to tens of thousands of times for observation and categorizing a material failure, is used for contamination identification. Energy dispersive spectroscopy (EDS), used in conjunction with SEM, is an analytical tool for the nondestructive chemical characterization of the material.

Testing for hardness, which determines a material’s resistance to deformation, is one of the additional metallurgical services offered in connection with fatigue failure analysis. Brinell, Vickers macro/microhardness, Knoop microhardness, Rockwell, and superficial Rockwell are a few examples of hardness test types.

SEM/EDS and metallography (MIC) are used to figure out what caused corrosion-related failures, such as weld deterioration, graphitic corrosion fatigue, galvanic pitting, crevice corrosion, stress corrosion cracking (SCC), and microbiologically influenced corrosion.

Microstructural analysis is used for qualitative observations and quantitative measurements that evaluate the effects of different manufacturing or heat treatment methods on a material in order to assess the processing history of metals. Grain size, grain flow/direction, grain structure, phase identification, nitriding presence, case depth, coating thickness, inclusion morphology, inclusion content, intermetallic phases, porosity, and void orientation are all factors in the microstructural examination.

A wide range of industries, including aerospace, automotive, defense and military, consumer products, manufacturing, maritime, nuclear, petrochemical, power generation, pulp and paper, utilities, polymer and plastics, and more, are tested by our fatigue failure analysis lab both domestically and internationally. In our cutting-edge labs, Infinita professionals provide reliable findings and analysis. To meet and/or exceed the needs of our clients, we adhere to quality assurance standards like ISO 17025 (A2LA), ISO 9001 Quality Management, Nadcap, and more.
