Jones, C., Hann, D. B., Voisey, K., & Aitken, S. (in press). Application of high speed filming techniques to the study of rearwards melt ejection in laser drilling. Journal of Laser Applications, 29(2), Article 022204. https://doi.org/10.2351/1.4983269

Melt ejection is the dominant material removal mechanism in long, ms, pulse laser drilling of metals, a process with applications such as the drilling of cooling holes in turbine blades. Droplets of molten material are ejected through the entrance ho... Read More about Application of high speed filming techniques to the study of rearwards melt ejection in laser drilling.

The effect of laser transformation notching on the controlled fracture of a high carbon (C70S6 ) steel (2008)
Journal Article
Zhang, D., Harris, S. J., McCartney, D., Pashby, I., Powell, J., Shipway, P., & Voisey, K. (2008). The effect of laser transformation notching on the controlled fracture of a high carbon (C70S6 ) steel. Materials Science and Engineering: A, 489(1-2), https://doi.org/10.1016/j.msea.2007.12.040

A high carbon (C70S6) steel has been laser surface treated using CO2 and Diode lasers in order to produce an embrittled region to act as a fracture notch. Such a process has been investigated as a precursor to the fracture splitting of automotive eng...
