A study was carried out to seek the element which did not affect the HAZ cracking of 75Ni-15 Cr-Fe alloy remarkably and improve the forgeability of it instead of Mg.
The main results obtained are as follows:
1. Using Ca, the range where HAZ cracking does not occur can be extended.
2. Using Ca, the mechanical and corrosion properties of 75 Ni-15 Cr-Fe alloy do not become worse.
3. Consequently, a weldable 75 Ni-15 Cr-Fe alloy which does not cause HAZ cracking can be made more easily using Ca.
