The driving force for titanium foam's replacement of existing materials in the aerospace sector results from the following five factors:
*Weight reduction: as a substitute for steels and nickel-based superalloys;
*Application temperature: as a substitute for aluminum and nickel-based alloys and steels
*Corrosion resistance: as a substitute for aluminum alloys and low-alloyed steels
*Galvanic compatibility: with polymer matrix composites as substitutes for aluminum alloys
*Space constraints: as substitutes for aluminum alloys and steels
The most urgent problem of engineering and its advanced branch of aerospace engineering is the efficient use of materials as well as increased service life.
