For example, the fracture toughness of diamond is about 7–10 MPa·m 1/2, [16] [17] which is high compared to other gemstones and ceramic materials, but poor compared to many metals and alloys – common steels and aluminium alloys have the toughness values at least 5 times higher.

Like many other alloys, titanium gold alloys have a higher yield strength, tensile strength, hardness, and magnetism than either of its constituent metals. [ 4 ] In July 2016, researchers led by Emilia Morosan at Rice University discovered that a titanium-gold alloy, β-Ti 3 Au, is an intermetallic alloy that is up to 4 times harder than pure ...
This is a list of named alloys grouped alphabetically by the metal with the highest percentage. Within these headings, the alloys are also grouped alphabetically. Within these headings, the alloys are also grouped alphabetically.
However, these are all based on empirical correlations, often specific to particular types of alloy: even with such a limitation, the values obtained are often quite unreliable. The underlying problem is that metals with a range of combinations of yield stress and work hardening characteristics can exhibit the same hardness number. The use of ...
increases hardness, tensile strength, and toughness. increases resistance to corrosion, heat, and wear. more than 11% makes it "stainless", by causing an oxide coating to form. [61] carbide inclusions reduce wear, but bulk material is softer. Cobalt (Co) increases strength and hardness, and permits quenching in higher temperatures.
Titanium alloy in ingot form. Titanium alloys are alloys that contain a mixture of titanium and other chemical elements. Such alloys have very high tensile strength and toughness (even at extreme temperatures). They are light in weight, have extraordinary corrosion resistance and the ability to withstand extreme temperatures.
An alloy is a mixture of chemical elements, which forms an impure substance (admixture) that retains the characteristics of a metal. An alloy is distinct from an impure metal in that, with an alloy, the added elements are well controlled to produce desirable properties, while impure metals such as wrought iron are less controlled, but are often ...
