Effects of hydrogen embrittlement in Al alloy used in engine blocks
Lead Researchers: Rashiga Wallalawita
Hydrogen internal combustion engine vehicle (HICEV) is considered to be a near emission-free method of transportation and has been heavily researched. Considering the strict emission requirements it is believed that a portion of future automobiles will be HICEVs.
Furthermore, with the current industry trend towards liner-less aluminum engine blocks, It is important to investigate the effect of hydrogen embrittlement on automotive aluminum alloys which are used for engine blocks.
The experiments required for this study are conducted at the newly constructed Hydrogen lab in UBCO.
Effects of blended hydrogen enriched natural gas on the microstructure and mechanical properties of a x42 steel pipeline and grade 290 weld
Lead Researcher: Austin Piche
Investigated the effects of hydrogen-enriched natural (HENG) blend on the microstructure and mechanical properties of an API 5L X42 pipeline for FortisBC. Tested and analyzed the ultimate tensile strength, yield strength, percent elongation, area reduction, fracture surface, microhardness, and phase compositions of the X42 through tensile tests, Vickers hardness testing and scanning electron microscope. These tests were conducted on the pipeline material both before and after exposure to the HENG at concentrations of 0%, 5%, and 20% for prolonged times in an enriched environment of 2 weeks, 2 months, and 6 months.
