Fibre laser piercing of mild steel: the effects of power intensity, gas type and pressure (2014)
Journal Article
Hashemzadeh, M., Powell, J., & Voisey, K. (2014). Fibre laser piercing of mild steel: the effects of power intensity, gas type and pressure. Optics and Lasers in Engineering, 55, https://doi.org/10.1016/j.optlaseng.2013.10.001

Laser piercing is used to generate a starting point for laser cutting. The pierced hole is normally larger than the kerf width, which means that it cannot lie on the cut line. An experimental program investigating the piercing process as a function o... Read More about Fibre laser piercing of mild steel: the effects of power intensity, gas type and pressure.

The application of specific point energy analysis to laser cutting with 1 ?m laser radiation (2014)
Journal Article
Hashemzadeh, M., Suder, W., Williams, S., Powell, J., Kaplan, A., & Voisey, K. (2014). The application of specific point energy analysis to laser cutting with 1 ?m laser radiation. Physics Procedia, 56, https://doi.org/10.1016/j.phpro.2014.08.110

Specific point energy (SPE) is a concept that has been successfully used in laser welding where SPE and power density determine penetration depth. This type of analysis allows the welding characteristics of different laser systems to be directly comp...

Effect of prior laser microstructural refinement on the formation of amorphous layer in an Al86Co7.6Ce6.4 alloy (2014)
Journal Article
Li, C., Murray, J., Voisey, K., Clare, A., & McCartney, D. (2014). Effect of prior laser microstructural refinement on the formation of amorphous layer in an Al86Co7.6Ce6.4 alloy. Applied Surface Science, 289, https://doi.org/10.1016/j.apsusc.2013.10.140

Laser surface melting (LSM) pre-treatment was conducted before large area electron beam (LAEB) treatment in an attempt to eliminate the cracking of the amorphous layer. In our previous work, LAEB treatment successfully generated an amorphous layer on...

Neutron strain scanning of fibre and diode laser welds in stainless steel and Ti6Al4V (2014)
Journal Article
Voisey, K., Folkes, J., Srithorn, J., & Hughes, D. (2014). Neutron strain scanning of fibre and diode laser welds in stainless steel and Ti6Al4V. Physics Procedia, 56, https://doi.org/10.1016/j.phpro.2014.08.051

Fibre lasers provide an unprecedented combination of high beam quality, brightness and low cost. Fibre laser beams can provide an exceptionally high power density beam with a relatively large depth of focus. Compared to more established laser welding...

Effect of Q-switched laser surface texturing of titanium on osteoblast cell response (2014)
Journal Article
Voisey, K., Scotchford, C., Martin, L., & Gill, H. (2014). Effect of Q-switched laser surface texturing of titanium on osteoblast cell response. Physics Procedia, 56, https://doi.org/10.1016/j.phpro.2014.08.027

Titanium and its alloys are important biomedical materials. It is known that the surface texture of implanted medical devices affects cell response. Control of cell response has the potential to enhance fixation of implants into bone and, in other ap...
