Effect of Post Weld Heat Treatments on the Elevated Temperature Mechanical Properties of Ti6Al4V Friction Welds [PDF]
arXiv, 2018 The {\alpha}+\b{eta} titanium alloy (Ti6Al4V) has been successfully joined using rotary friction welding. To investigate the influence of post weld heat treatments on the microstructure and mechanical properties of the welds, the weld joints were heat treated in {\alpha}+\b{eta} and \b{eta} regions, followed by air cooling and furnace cooling ...

Transmission factors and exposure to infections at work and invasive pneumococcal disease
American Journal of Industrial Medicine, Volume 66, Issue 1, Page 65-74, January 2023., 2023 Abstract Background Working in close contacts with coworkers or the general public may be associated with transmission of invasive pneumococcal disease (IPD). We investigated whether crowded workplaces, sharing surfaces, and exposure to infections were factors associated with IPD.
