概要
- 論文の詳細を見る
Deformation and cracking behavior of weld metal of Fe-36% Ni alloy Invar reheated in hot stage microscope is observed dynamically to reveal the behavior and mechanism of reheat hot cracking in weld metal of this alloy. It is shown that grain-boundary sliding and its resultant cavity formation and coalescence precede the occurrence of the reheat hot cracking. It is also suggested that grain-boundary migration improves the hot ductlity.
