Of all hardfacing applications, tool-and-die repairs are one of the most metallurgically challenging. What makes it so challenging is the metallurgy of the base materials and their compatibility with the hardfacing products, as well as the post-weld heat treatments required.
Additive manufacturing techniques are no longer in their infancy. They are quickly emerging into serious options for the production of metallic parts. Forge shops should keep a watchful eye on this unfolding technology, both as a competitor and as an opportunity.
is the main constituent in titanium alloys, of course, but they can contain a
significant amount of other elements, which are added for a variety of
metallurgical reasons. The strength of titanium alloys can often be comparable
to steel, but they have the advantage of having only about 60% of the weight.
