Titanium alloy: WTi Alloy Tungsten-tirongmetal

Titanium alloys are alloys containing a mixture of titanium and other chemical elements.This alloy has very high tensile strength and toughness (even at extreme temperatures).They are lightweight, have extraordinary corrosion resistance and the ability to withstand extreme temperatures.However,the high cost of raw materials and processing limits their use in military applications,aircraft,spacecraft,bicycles,medical equipment,jewelry, high-stress components such as connecting rods on expensive sports cars,and some advanced sports equipment and consumer electronics use.Although "commercially pure" titanium has acceptable mechanical properties and has been used in orthopedic and dental implants,for most applications titanium is alloyed with small amounts of aluminum and vanadium,typically 6% by weight and 4% by weight.This mixture has a solid solubility that varies significantly with temperature,making it capable of precipitation strengthening.This heat treatment process is carried out after the alloy has been worked into its final shape but before it is put into service, making it easier to manufacture high-strength products.


Alloys are mixtures of chemical elements,at least one of which is a metal.Unlike compounds with a metal base,alloys will retain all the properties of metals in the resulting material,such as conductivity,ductility, opacity and luster,but may have properties different from pure metals,such as increased strength or hardness In some cases,alloys can reduce the overall cost of a material while retaining important properties.In other cases, the mixture imparts synergistic properties to the constituent metal elements, such as corrosion resistance or mechanical strength.Alloys are defined by metal bonding properties.Alloy composition is usually measured in mass percent in practical applications. Alloys are often classified as substitutional or interstitial alloys,based on the arrangement of atoms that form them. They can be further classified as homogeneous (composed of a single phase) or heterogeneous (composed of two or more phases) or intermetallics.Alloys can be solid solutions of metallic elements (single phase in which all metal grains (crystals) have the same composition) or mixtures of metallic phases (solutions of two or more forming a microstructure of different crystals within the metal).Examples of alloys include red gold (gold and copper), platinum (gold and silver), pure silver (silver and copper), steel or silicon steel (iron containing non-metallic carbon or silicon respectively), solder, brass, tin alloys, Duralumin, bronze and amalgam.Alloys are used in a wide variety of applications, from steel alloys for construction, automotive, surgical tools, to special titanium alloys for the aerospace industry, to beryllium copper alloys for non-sparking tools.


Titanium alloys are generally divided into four categories:

  • Alpha alloys containing only neutral alloying elements (such as tin) and/or alpha stabilizers (such as aluminum or oxygen).These are not heat treatable.Examples include:Ti-5Al-2Sn-ELI, Ti-8Al-1Mo-1V.

  •  Near alpha alloys contain small amounts of ductile beta phase.Near-alpha alloys are alloyed with 1-2% beta-phase stabilizers such as molybdenum, silicon,or vanadium in addition to the alpha-phase stabilizer.Examples include:Ti-6Al-2Sn-4Zr-2Mo,Ti-5Al-5Sn-2Zr-2Mo, IMI 685, Ti 1100.

  • Alpha and beta alloys,which are metastable,usually contain some combination of alpha and beta stabilizers, and can be heat treated.Examples include:Ti-6Al-4V,Ti-6Al-4V-ELI, Ti-6Al-6V-2Sn, Ti-6Al-7Nb.

  • Beta and near-beta alloys,which are metastable and contain enough beta stabilizers (such as molybdenum, silicon, and vanadium) to allow them to retain the beta phase when quenched, and can also be solution treated and aged to increase strength.Examples include:Ti-10V-2Fe-3Al, Ti–29Nb–13Ta–4.6Zr,Ti-13V-11Cr-3Al,Ti-8Mo-8V-2Fe-3Al, Beta C, Ti-15 -3.


Beta titanium alloys exhibit the BCC allotropic form of titanium, known as beta.The elements used in this alloy are one or more of the following elements,but with varying amounts of titanium.These are molybdenum, vanadium, niobium, tantalum, zirconium, manganese, iron, chromium, cobalt, nickel and copper.Titanium alloys have excellent formability and are easy to weld.β titanium is now mainly used in the field of orthodontics, and was used in orthodontics in the 1980s.This type of alloy has replaced stainless steel in some uses,which has dominated orthodontics since the 1960s.It has nearly twice the strength/modulus ratio of 18-8 austenitic stainless steel, greater elastic deflection of the spring, and 2.2 times lower force reduction per unit displacement than stainless steel appliances.Some β-titanium alloys can be transformed into hard and brittle hexagonal omega-titanium at low temperature or under the influence of ionizing radiation.

Transition temperature

The crystal structure of titanium at normal temperature and pressure is a close-packed hexagonal α phase, and the c/a ratio is 1.587. At about 890 °C, titanium undergoes an allotropic transformation to the body-centered cubic beta phase,which remains stable at the melting temperature.Some alloying elements,called alpha stabilizers,increase the alpha to beta transition temperature,while other elements (beta stabilizers) decrease the transition temperature. Aluminum,gallium,germanium,carbon,oxygen and nitrogen are alpha stabilizers.Molybdenum,vanadium,tantalum,niobium,manganese,iron,chromium,cobalt, nickel,copper and silicon are beta stabilizers.
