The present study investigates the fracture toughness of FSW X80 HSLA steel welds. Weld cooling rate and peak temperature were varied among welds; indirectly manipulated through travel speed, rpm, weld preheat. Fracture was tested according to ASTM 1820 standard along centerline using surface-notched SEB specimen cooled −40 °C. Results demonstrate that CTOD has a strong inverse linear correlati...
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...
To examine the effect of attenuated epinephrine and elevated insulin on intramuscular hormone sensitivity lipase activity (HSLa) during exercise, seven men performed 120 min of semirecumbent cycling (60% peak pulmonary oxygen uptake) on two occasions while ingesting either 250 ml of a 6.4% carbohydrate (GLU) or sweet placebo (CON) beverage at the onset of, and at 15 min intervals throughout, ex...
