摘 要: 加工变形量ε和Q是管材冷轧变形的重要参数。通过三辊冷轧方式制备小规格TA18管材,并在不同温度下进行退火处理。研究不同加工变形量ε和Q对管材性能和表面质量的影响,分析不同退火温度下各管材的室温拉伸性能和显微组织,探索退火温度对TA18管材性能和组织的影响。结果表明:TA18管材具有较好的冷加工性能,变形量在12%~48%,且Q≤1.30时,管材表面质量较好,通过不同的退火温度(350~380℃,600~750℃),可获得满足不同强度级别要求的TA18管材。

Abstract:Machining deformations ε and Q are important parameters for cold rolling of tubes. The small size tubes of TA18 were prepared by cold rolling through three-roll tube reducers. The effects of different machining deformations ε and Q values on the properties and surface quality of tubes were investigated, the tensile properties at room temperature and microstructures of tubes under different annealing temperatures were analyzed, and the effect of annealing temperature on the microstructure and properties of TA18 tubes was studied. The results show that TA18 tubes have good cold working properties, the surface quality of tubes is good when the deformation rates range from 12% to 48% and the Q value is not more than 1.30. The TA18 tubes have excellent properties to meet the requirements of different intensity levels after different annealing treatments (350-380 ℃, 600-750 ℃).
