The effect of pressure and temperature variations on the FEM prediction of deformation during extrusion [PDF]

, 2005
The extrusion process is complex, involving interaction between the process variables and the material’s high temperature properties and is typically conducted at relatively high temperatures because the lower flow stress of the material permits larger ...

Study on adhesion mechanism of fouling organisms on marine steel surface based on inverted microscope [PDF]

E3S Web of Conferences
Marine stainless steel is immersed in seawater for a long time, and its surface will inevitably adhere layer by layer to form biofilm, which will lead to microbial corrosion of the material.
