Thermal analysis of Portevin-Le Chatelier Effect in AlMg alloys The Portevin-Le Chatelier (PLC) effect is a dynamic instability observed in certain alloys under plastic deformation, particularly at intermediate temperatures and strain rates. It manifests within multiple alloys as serrated yielding on stress-strain curves, attributed to the interaction between mobile dislocations and diffusing solute atoms. This phenomenon is a result of dynamic strain aging...

Multispectral Imaging of CO2-free Hydrogen Combustion for Industrial Annealing Processes and Comparison to Natural Gas The drive to transition towards greener methods for energy production and industrial processes is stronger every year. Typical combustion reactions create well known gas products (CO2, H2O, CO, etc…) and governments as well as the industry are pushing to limit the amount of greenhouse gases emitted every day. A great example of this effort is the research accomplished at the Instituto de Tecnol...

Direct Imaging of Shale Gas Leaks Using Passive Thermal Infrared Hyperspectral Imaging There are many types of natural gas fields including shale formations that are common especially in the St-Lawrence Valley (Canada). Since methane (CH4), the major component of shale gas, is odorless, colorless and highly flammable, in addition to being a greenhouse gas, methane emanations and/or leaks are important to consider for both safety and environmental reasons.Telops recently launched ...

Volcanic Eruption Observations from an Elevated Point of Stromboli Using Thermal Infrared Hyperspectral Imaging The Stromboli volcano is well known for its periodic eruptions of small magnitude containing various proportions of ash, lava and gases. Imaging was carried out at a relatively high spectral and spatial resolution before and during eruptions from the North-East crater. Both sulfur dioxide (SO2) and silicon tetrafluoride (SiF4) could be successfully identified within the volcano’s plume from the...

High-Speed Infrared Imaging of Metal Parts Fabrication by Additive Manufacturing Additive manufacturing, also known as 3D printing, is considered by many to be the biggest industrial revolution since the Internet. This method allows rapid fabrication of metal pieces with various compositions, shapes and sizes. However, the extremely high thermal gradients involved in this fabrication process can induce stress and deformation in the materials. In an effort to better understa...
