Abstract:The effects of heat processing and heat treatment technology on combination properties of TB2 alloy were studied. The experiments show that inspiratory thickness is reduced when two-step heating way is used so as to improve the surface quality of forging and rolling. Strength of the alloy is increased after solution and aging treatment; however, plasticity is decreased. The optimum properties of high strength and good ductility can be obtained by aging at deformation stage.
