Analysis of tool traverse speed in Friction Stir Welding of AZ31 Magnesium alloy thin plates
(Universidade Federal de São Carlos, 2021-02-25)
The automotive industry's great interest in lightweight materials, such as
magnesium alloy AZ31, reflects the growing importance of reducing cars' weight.
One of the challenges of using such alloys is that their welding ...
Previsão de viscosidade e temperatura liquidus de vidros óxidos via redes neurais artificiais
(Universidade Federal de São Carlos, 2020-04-30)
The number of glass compositions that have already been studied (~10^5) is many times smaller than the potential glass compositions (~10^52). The traditional method “cook and look” all of the potential compositions to ...
