Making iron aluminides out of scrap | Journal of …

It is possible to obtain iron aluminides using exclusively recycled raw materials and a low-cost processing route. 2. Carbon can be added to the alloy simply by using a graphite crucible or by placing the melt in contact with graphite tools, suggesting that adding graphite pellets to the load is unnecessary in processing iron aluminides.

1/12/1991· For these reasons, titanium aluminides are prime candidates to replace conventional titanium alloys (which lose their strength at about 1000[deg.]F) and lower-temperature nickel-base superalloys. In addition, metal-matrix composites using reinforced titanium aluminide alloys appear to have the potential to surpass the monolithic titanium aluminide alloys in several important areas.
