Titanium Metal Matrix Ceramic Composite

A metal matrix composite mmc is composite material with at least two constituent parts one being a metal necessarily the other material may be a different metal or another material such as a ceramic or organic compound when at least three materials are present it is called a hybrid composite an mmc is complementary to a cermet.

Titanium metal matrix ceramic composite.

Titanium metal matrix composites ti mmcs have offered the promise of significant weight savings since their initial development in the early 1960s but until recently their inadequate quality and reproducibility combined with high processing and materials costs have prevented their introduction into production applications. The fiber materials are b sic al 2 o 3 and refractory wires of tungsten alloy w 2 pct tho 2 and molybdenum alloy tzm. Titanium metal matrix composites tmcs provide an alternative to overcome these shortcomings. 350 f 177 c initial 2000 f freestanding fire.

1650 f 900 c structural applications. Tmcs have been under significant development and evaluation in the past 30 years for use in aircraft engines and airframe applications. The matrix metals included in this study are aluminum titanium magnesium and a superalloy mar m 200 of martin marietta co. Figures 8 10 show the performance of the composite systems in terms of the young s modulus e x and e y in the two mutually orthogonal.

Aircraft engine components ducting oil gas tubing advanced energy motorsports. At present the most industrially valuable composite materials are polymer matrix composites pmcs ceramic matrix composites cmcs and metal matrix composites mmcs. The high specific modulus of tmcs is the main catalyst behind its usage for airframes applications while the. Titanium matrix composites firmetal 2019 01 08 09 28 00 pm.

Unlike other metal matrix composites titanium composites show a much lower wear of the counterpart because the particles like tic or tib show some self lubricating behavior. Solvent based ceramic matrix composite cmc prepreg high strength. 1 2 mmcs are made by. Metal matrix composite mmc metal ceramic composites in light metal construction the range of applications for high strength light metal components primarily aluminum but also magnesium and titanium is constantly growing.

Metal matrix composite or mmc for short is a composite material artificially combined with one or more metal or non metal reinforcing phases with metal and its alloys as the matrix. The ductility is lower than for conventional titanium alloys however recently developed titanium composites show good ductility values.
