Technology for Making Sparingly Alloyed Titanium Foundry Alloy VT40L

Resumo

Results are presented from studies performed to develop a technology for obtaining ingots of sparingly alloyed titanium foundry alloy VT40L by vacuum-arc remelting in a VD5M furnace. The structure and phase composition of the alloy and the degree of segregation of the main alloying elements over the volume of the ingot are studied. The research results are used to give recommendations on a refining regime that ensures the production of chemically and structurally homogeneous ingots.
