Microstructure and mechanical properties of vacuum

2018/9/1Therefore the pre-sintered product was taken as charge material and melting was carried out under vacuum (2.3 10 −4 mbar) in vacuum induction furnace (GCA/vacuum industries, USA). The furnace crucible was lined with magnesium oxide (MgO) and has a capacity of 50 kg melts with maximum temperature up to 1650 C.

Vacuum induction melting

Vacuum induction melting (VIM) utilizes electric currents to melt metal within a vacuum.The first prototype was developed in 1920. Induction heating induces eddy currents within conductors. Eddy currents create heating effects to melt the metal. Vacuum induction

EFFECT OF VACUUM INDUCTION MELTING

This paper dealt with the effect of different induction melting technologies on mechanical properties of Nb-16 Si-22 Ti-2 Al-2 Hf-17 Cr alloy. The cast ingots were fabricated first by arc-melting, and then remolten in the vacuum induction furnace. The results showed that
