In order to make up for the poor high temperature strength and low oxidation resistance of pure molybdenum alloy, producers often dope appropriate amount of additives such as zirconium hydride, yttrium oxide and cerium oxide in their production process

Like TZM alloy (molybdenum-titanium-zirconium alloy) and MHC alloy (molybdenum-titanium-zirconium-carbon alloy), TZC alloy (molybdenum-titanium-zirconium-carbon alloy) is also a high-temperature-resistant molybdenum-based alloy, which is widely used in places with harsh working environments.

TZM alloy is currently the most widely used molybdenum alloy with the best performance. TZM alloy has good high temperature strength, creep resistance and high recrystallization temperature, so it is often made into nozzles, perforated heads, molds, heat shields and grids in high-power ceramic tubes.

Because recrystallization TZM alloy at room temperature is fragile and it is hard to deform. So before cool and warm rolling should avoid annealing at perfect recrystallization.

TZM alloy has good high temperature mechanical property, but at a high temperature oxidation resistance property is poor. Under high temperature, it unable to form a protective oxide layer, so it must be used at high temperatures in non-oxidizing atmosphere. When the temperature is below 400 ℃

The strengthening mechanism of TZM alloy is divided into: solid solution strengthening, second phase strengthening and deformation strengthening.

The degree of deformation is one of the main factors affecting the densification process of the TZM alloy slab, and it also ultimately affects the mechanical properties of the TZM alloy slab. When the TZM alloy plate is rolled,the degree of deformation of the material is expressed by the compression

Titanium alloy has some special requirements on isothermal forging, for example, there are some special requirements on mold temperature, pressure and dwell time. During isothermal forging the mold temperature should be at 850~950 ℃ and pressure should be control at 100~120 MPa.

Molybdenum alloy is a non-ferrous alloy composed of molybdenum as a matrix and other elements added. The main alloying elements are titanium, zirconium, hafnium, tungsten and rare earth elements.
