Due to its well-known superior strength to weight ratios, titanium has become a more and more critical material choice in aerospace applications which require heavy loading.
Due to titanium’s high chemical activity welding can be a real challenge but to overcome this, new technologies are being developed which uses the slag pool and argon to shield the weld site from interstitial element contamination. Continue reading

High Entropy Alloys: Part One
As technology increases to become more advanced and complex it puts an ever increasing demand on materials and their performance to keep pace.
Currently the application of high entropy alloys is restricted currently to protective coatings for high temperature components however it is a rapidly developing field which will soon diverge to cover materials which have high loading conditions coupled with extremely high temperatures.

High Chromium Cast Iron: Part Two
High chromium cast irons (HCCI’s) exhibit very good mechanical properties and offer benefits for a range of manufacturing applications.
One of the main flexibilities exhibited is the possibility of HCCI’s to have different matrix structures in different treatment states whether it be austenite in casting state, pearlite in annealing state, martensite in quenching state, and tempered martensite in tempering state.
