... shown in the near-surface region is a void that is formed in most metallic depositions at thermal energies. The random nature of the positions along the surface, where the vapor atoms land, coupled with the low mobility of the atoms after impact, leads to void formation. The upper left portion of Fig...

The molten substance assists in pore elimination by drawing the particles together and filling void spaces. The undesirable small pores are the first to disappear. Thus, the extent of fusion determines pore...

... entrapped air out through the mold walls. The result is voids and porosity. Thus, this 8-in.-long casting as originally designed, with a 0.060-in. wall thickness and five cross members, is incapable of being properly filled. The problem can be solved in at least three ways. First, the outer wall thickness...

Various criteria for describing coalescence via such an internal necking process have been based on (1) a critical matrix-ligament strain, ε cr , (2) a critical stress, or (3) a critical void volume fraction. The first criterion is the one applied in most cases. The critical matrix...
