Defects Easy Occur in VAR Titanium Ingots
VAR ingots are still main primary semi-products of titanium and its alloys up to now in the world. Due to special vacuum melting principles and operation reasons,some defects are easy occurring during preparation procedure and exist in the final ingots products,whether it is unavoidable, detrimental or not considering the latter processing. Surface or near surface defects include skin oxidation,dirty substance white,grey or black, shaggy,goffer,and pores under surface,etc. Inside defects include shrinkage holes during hot topping, chemical composition fluctuation,macro-segregation , undesired inclusions, alloying elements dissolved insufficiently during melting, etc. Some suggestions are also mentioned to improving the quality of titanium ingots in industrial scale.
