• Understanding Material Forging Defects 

  In this second of two articles, authors Van Tyne and Walters examine defects that can occur in forgings because of microstructural irregularities or ductile fracture.

• Understanding Geometrical Forging Defects 

  In this first of two articles, authors Van Tyne and Walters examine possible causes and remedies of geometrical forging defects, which are generally related to process design.

• Multiscale Analysis of Void Closure During Hot Forming Process 

  In the metal forming industry, elimination of internal defects is a prerequisite to avoid catastrophic failure of workpieces. The two different approaches used in the literature to study void closure, respectively at the process-scale and void-scale,
