Paragraph starter

Research by Bergamini et al. (2013) highlights the critical role of precise temperature control during the hot extrusion of Ti-6Al-4V. Their findings indicate that deviations in billet and die temperatures directly correlate with the formation of defects such as cracks and surface imperfections, and impact microstructural homogeneity. This underscores the importance of integrating manufacturing process knowledge, particularly thermal management, into the design phase to ensure the successful production of complex titanium alloy components.
