The Effect of Nb on Microstructure and Properties of GH4169 Alloy Pipe

With the manufacturing process by vacuum induction， electroslag remelting， vacuum self consumption， homogenization heat treatment， forging， hot extrusion， cold rolling， and heat treatment. we can get two types of GH4169 alloy pipes with Nb content of 4.90% and 5.30% respectively. The effect of Nb co...
