Core characteristics of TZM alloy

High temperature performance:

The melting point is as high as 2610℃,and it can work for a long time at 1200℃~1800℃(better than pure molybdenum).

The high temperature tensile strength is significantly better than pure molybdenum(such as 30%~50%higher strength at 1500℃).

Creep resistance:The solid solution strengthening effect of Ti/Zr suppresses high-temperature deformation and is suitable for withstanding long-term thermal stress.

Corrosion resistance:It has good resistance to molten metals(such as copper and aluminum),non oxidizing atmospheres(H₂,Ar),and some acids and bases.

The recrystallization temperature is high:about 1400℃(1000℃for pure molybdenum),and the fine crystal structure is still maintained at high temperatures.

Difficulties in Processing and Manufacturing

Precision molding:

Powder metallurgy(HIP hot isostatic pressing)or smelting forging requires control of Ti/Zr composition segregation.

Complex structures require slow wire cutting(accuracy±0.01mm)or laser processing.

Welding process:

Electron beam welding or argon arc welding(preheated to 800℃to avoid cracking).

Surface treatment:

Silicide coatings(such as MoSi₂)enhance oxidation resistance(up to 1700℃).

Polishing or nickel plating reduces the risk of high-temperature adhesion.
