Multiphase tungsten alloy belong to transformation material, resistance to deformation larger than uniphase tungsten alloy, but to concerned the comprehensive strength, muitiphase tungsten alloy much nore better than uniphase tungsten alloy.
 
Multiphase tungsten alloy be seriously harden by hot or cold working for it’s rod, wire material during casting process, besides,on proper temperature,carbide intensify also make multiphase tungsten alloy with dynamic deformation trends,thus result in rapid harden of material and reduce further processing ability.
 
Main factors impact cast of multiphase tungsten alloy include: alloying level of multiphase tungsten alloy,deformation temperature and so on. Tungsten radicalα-solid solution and carbide ZrC compose the phase of multiphase tungsten alloy. Use twice high temperature extrusion ingot with  1700 vacuo recrystallization annealing for 5 hours rods obtained, further rotary swaging and drawing made thin rods and wire. Multiphase tungsten alloy often applied with this form. Tungsten phase electrochemistry dissolution precipitated phase during casting processing,when the temperature high than 1400 ,due to the intensify heat activity  of dislocation cross slip ,lead to alloy soften at high speed, thereout multiphase tungsten alloy.
 
Multiphase tungsten alloy with especially high hardness,the contribute to strength of tungsten alloy much more exceed traditional cognition, compare to uniphase tungsten alloy, multiphase tungsten alloy improved in strength ,resistance deformation plasticity ability .
