High-temperature hardness testing machine
EF 2006-07
Résumé
In many cases, mechanical structures serve at elevated temperatures, for example, gas turbine engines, cutting tools and pressure vessels. Most metallic materials lose their hardness and strength at high temperatures due to the promoted atomic motion. Therefore high-temperature properties of materials have attracted more and more attention. The applicant, Dr. R. Liu, is leading a group in material research. Three of the projects involve high-temperature materials (Stellite alloys and Tribaloy alloys as well as their composites) and surface coatings, which are sponsored by NSERC CRD grants, with the industrial support of Deloro Stellite Inc. These materials are developed for high temperature corrosion/wear applications. Hardness is one of the important factors in characterization of a material. It is the characteristic of a solid material expressing its resistance to permanent deformation and commonly refers to a material's ability to penetrate softer materials. In particular, hardness is quite often used in the field of wear resistance as the criteria for judging alloys, castings, hardfacings and overlays. The premise is that the harder the material, the greater the wear resistance. In general, the hardness of metallic materials decreases with temperature, especially when the temperature reaches a critical level, the hardness drops steeply, depending on individual materials. As a result, the performance and properties of a material characterized at room temperature do not reflect its real ability at elevated temperatures. The proposed equipment, high-temperature hardness testing machine, has the capacity of measuring the hardness of a material at elevated temperatures, which will provide the important data for judging alloys and castings in wear resistance and relevant mechanical performance, for example, deformation resistance, and will make significant impact on the material research of the applicant's group. The developed new high-temperature materials in the applicant's group have potential application in various fields of engineering such as aerospace, automobile, oil and chemical industries, which will definitely benefit the accruing of Canadian economy.
