Abstract

Abstract

The microstructures and tensile behaviors of high-titanium maraging stainless steel under different ageing treatments were studied by means of metallurgical microscope, scanning electron microscope, transmission electron microscope and tensile testing machine. Microstructures observations shows high-titanium maraging stainless steel with different ageing treatments consist of martensite and a small amount of austenite, and there are a large number of nano-scaled Ni₃Ti precipitates in the martensite matrix. The lengths of Ni₃Ti precipitates in 1050-480, 1050-500, 1050-530 and 1050-550 samples are 11.5, 7.9, 15.9 and 33.1 nm, respectively, and their corresponding widths are 2.8, 2.8, 4.3 and 7.8 nm, respectively. As Ni₃Ti precipitates size increases, their distribution gradually becomes sparse, consequently the tensile strength of high-titanium maraging stainless steel decreases and the plasticity improves, and the resulting tensile fracture characteristics change from brittle cleavage fracture to ductile dimple fracture.
