Review on Processing & applications of refractory metal bar

Most common processing for refractory mental is sintering, that is press powder or mixed powder into certain shape, sintered in vacuum sintering furnace. This forms simply sintered metal blanks. Different temperature & sintering time is used for different material and dimensions. Simply sintered metal bars are basically used as additive in stainless steel and other no-ferrous alloys, to improve the properties. It only requires purity and limits gas elements for this usage.
Other applications which requires the material to be more dense, uniform grain, better machinability, resistance on temperature & wear. Forging, & repeat forging can make the material suitable for these applications. Metal bars can be forged from ingots, or smaller bars are cut from plates. Below we listed the applications for forged metal bars.
Niobium bar application: Electronic industry, chemistry, electronic industry, steel, ceramics, electronics, nuclear energy industries, and superconductor technology; melted cast ingots and alloying agents. Widely used in manufacturing various kinds of alloy steel, high temperature alloy, optical glass, cutting tool, electronics and superconducting materials and other industries.
Molybdenum bar application: Produce crucible for all the traditionally utilized procedures in the field of sapphire development, utilized as upgraded dissolving and cementing vessels, a wide range of glass liquefy, high power densities and the progression of power through power diodes and transistors create heat. molybdenum and its compounds are the ideal substrate for power hardware. At the point when utilized as a base plate, molybdenum dependably disseminates heat. Also, used as in other high temperature furnaces.
Based on different physical properties, Mechanical properties, Chemical properties, Machinability, Recrystallization behavior. Molybdenum alloys with various scopes of properties which are unequivocally built to meet the necessities of every individual application.
