Correlating Macroetch Response to Microstructural Features - Cooler Campaign - September 2021

#ItBeALotCoolerIfYouDid Correlating Macroetch Response to Microstructural Features A PES internship summer project investigated how chemical segregation in steels can impact the appearance of macroetch test samples. The purpose of this project was to compare corresponding macroetch and microetch features to analyze how the underlying microstructure can affect the stronger macroetch process. Three different alloys were examined as part of the project, namely 4340, 4140, and 4

Corrosion Testing -Cooler Campaign - August 2021

#ItBeALotCoolerIfYouDid Corrosion Testing Corrosion is the process of degrading materials (e.g., metal) chemically and can occur naturally or in controlled acidic/basic environments. Natural atmospheric corrosion involves the oxidation of atoms on the surface of the material. This oxidation occurs due to a combination of slightly acidic water contacting the surface and oxygen in the air reacting with the surface. In some controlled environments, several types of acids are use

High Cycle Fatigue Testing - Cooler Campaign - July 2021

#ItBeALotCoolerIfYouDid High Cycle Fatigue Testing Typically, High Cycle Fatigue (NCF) Testing is performed in the elastic region (i.e. before yielding) of a material. HCF Testing is useful for simulating specific scenarios and investigating real world failures. This type of testing can be performed on many different types of conventional and additively manufactured materials. Test specimens preparation is critical for fatigue testing. When machining fatigue test specimens, a

Low Cycle Fatigue - Cooler Campaign - June 2021

#ItBeALotCoolerIfYouDid Low Cycle Fatigue Low Cycle Fatigue (LCF) Testing is typically performed in the plastic region (i.e. at or beyond yielding) of a material that experiences cyclic load or strain and/or temperature fluctuations in service. LCF is conducted primarily for the aerospace, oil and gas, and automotive industries on carbon steels, stainless steels, nickel and aluminum alloys. One of the most common applications to be evaluated by LCF testing is rotating compone

Transverse Rupture Strength -Cooler Campaign - May 2021

#ItBeALotCoolerIfYouDid Transverse Rupture Strength Testing Transverse Rupture Strength (TRS) Testing is commonly performed on cemented carbides - a combination of fine particles mixed into a composite with a binder metal. They are sintered together by the application of pressure and heat which fuses the metal and other particles with higher melting points. Cemented carbide was initially developed in Germany in the 1920s, to replace costly diamond as a material for machining

Effective Case Depth Measurement- Cooler Campaign - April 2021

#ItBeALotCoolerIfYouDid Effective Case Depth Measurement Case-hardening occurs when the surface layer hardness of a ferrous metal is increased, forming what is known as a "case" layer over the remaining, unaffected "core" material. For rotating components involved in industries such as automation and defense, case hardening is desirable. It serves as a protective shell that is both stronger and more wear resistant than that of the original metal, prolonging part lifespan and

Coating Weight Measurement - Cooler Campaign - March 2021

#ItBeALotCoolerIfYouDid Coating Weight Measurement Coatings are applied to substrate materials for many reasons, including corrosion/environmental protection, wear resistance, chemical resistance, enhanced electrical conductivity, improved adhesion, aesthetics, and other purposes. The amount of coating applied to a product over a given surface area can be determined by calculating the coating weight. The total coating layer thickness used varies based on the application. Rela

Drop Weight Testing - Cooler Campaign - Feb 2021

#ItBeALotCoolerIfYouDid February 2021 - Drop Weight Testing Drop Weight Testing was developed by the Naval Research Laboratory in 1952 and is still used by naval, nuclear, freight, and railcar industries to determine the Nil-Ductility Transition (NDT) Temperature for a variety of ferritic steels. The NDT is defined as the temperature at which the fracture mode of the material changes from ductile to brittle or the maximum temperature at which a material exhibits brittle fract

Blue Etch Anodizing of Titanium #CoolerCampaign - Jan 2021

#ItBeALotCoolerIfYouDid January 2021 - Blue Etch Anodizing of Titanium Visual examination for defects is an essential step in evaluating the processing and manufacturing of metal products, as their presence can negatively affect overall properties, such as strength, fatigue resistance, or corrosion resistance. Some defects are identifiable on a macroscale, while others are only visible at higher magnifications after special preparation. In machined and/or polished samples, ev

LinkedIn Giveaway Campaign for 2021

Our Recommended Reading Campaign for 2020 was a huge success and we thank everyone who participated and congratulate all of the winners. Through this campaign we gave away 36 copies of books PES team members have read and found to be influential in helping them lead, manage and/or communicate more effectively. We are excited to announce that our next monthly give-away campaign will start in January 2021. The name of this one? It Be A Lot Cooler If You Did. #ItBeALotCoolerIfYo
