Abstract:
The report begins with a short explanation of why a large titanium content was thought to be a detrimental to toughness of maraging steels. Several metallurgists have identified the fracture nucleating particles in maraging steels as titanium nitrides and titanium carbides. An experimental titanium-free maraging alloy was developed. Two heats were tested one was of laboratory quality, and one of a quality as might be expected from production heats. Both base plate and welded samples are considered from each heat. Welding with the new titanium-free alloy proved to be a problem which has not yet been solved. At best the new alloy offered only a slight improvement over the normal alloy. The required high purity and difficulity with welding make use of this new alloy impractical at the present time. Author
