- 論文の詳細を見る
Effects of solidification rate on solidification structure were investigated using moving heat sources of welding arc and electron beam. Solidification rate was varied in the wide range from about 10 to 10^7℃/sec by means of variation of welding heat input for AISI310 austenitic stainless steel and Fe-20 (wt%) Mn alloy. The sizes in the columnar grains and the primary and the secondary arm spacings in the subgrains were measured in the inward location in the weld metal. Moreover the relations between the arm spacings and the solidification rate in weld metal were investigated.
