In this study, the effects of Mo and Nb on microstructure Charpy impact properties coarse-grain heat affected zone (CGHAZ) in high-strength low-alloy (HSLA) steels were investigated. The high-Mo steel had a lower volume fraction acicular ferrite (AF) higher granular bainite (GB) than those low steel. CGHAZ specimen AF GB compared to low-Mo specimen. This is because, an increase lowers transform...

This research effort focuses on the evaluation of existing design standards for cold-formed steel stud walls and the development of retrofit wall systems. Full-scale wall systems are tested under uniform static pressure using a vacuum chamber. The resistance functions obtained are used to model the dynamic behavior of the walls and to predict performance under blast conditions. This paper focus...

According to the deformation and movement requirements of the FAST reflector, a multipurpose analysis, including the load-bearing behavior, deformation, construction costs of the reflector supporting structure and its model, is presented in this paper. The advantages and disadvantages of steel and aluminum alloy structures are also discussed and compared through detailed design calculations und...

When the author left the sugar industry in 1986, he requested and wasgranted permission by Tongaat-Hulett Sugar to commercially exploit the design of the coupling. A milldrive coupling was designed along the same lines as the original Amatikulu couplings, but pricing the various components indicated that the coupling would be too expensive to sell. Thoughts about ways to reduce costs by elimina...
