... and the distribution of gas porosity was investigated. Microhardness analysis was also conducted on both 1 g and reduced gravity samples to assess variations in material hardness. A statistically significant difference in droplet diameter and frequency was found. This difference is attributed to the reduction...

... was proposed based on microstructure, microhardness, and residual stresses of CD stud welded joint. The results show that a narrow weld seam with a widmanstaten structure is formed because of quick cooling. For the longer stud extension length, the width of the weld zone becomes wider and the microstructure...
