Investigation of microstructural match at friction welded TC17/TA19 interface based on β reconstruction under various frictional linear speeds

Journal of Materials Research and Technology
TC17 (α+β titanium alloy) and TA19 (near-α titanium alloy) are often joined in aerospace compressor rotors by rotary friction welding, but their differing phase transformation behaviors cause a mismatched microstructure at the weld interface.

Residual Stress Analysis in Linear Friction Welded Ti17

Materials
Residual stresses with a complex distribution are generated after linear friction welding, which affects the service performance of the weldment. In this work, a numerical model for linear-friction-welded Ti17 (Ti-5Al-2Sn-2Zr-4Mo-4Cr) was developed to investigate the evolution of residual stresses and the effect of welding parameters on residual ...

Characteristics, properties and limitations of per‐ or polyfluoroalkyl substances (PFASs) and fluoropolymers

Polymer International, EarlyView.
An overview and categorization of man‐made per‐ or polyfluoroalkyl substances (PFASs) including low‐molar‐mass and high‐molar‐mass fluorochemicals, and their international regulations is presented. Though certain PFASs are toxic, bioaccumulative and cross the human cellular membranes, others, such as fluoropolymers, are safe, reliable and involved in ...
