摘要
为了研究铝和硅质量分数更高的合金,利用真空感应炉对高锰和高铝合金进行熔炼,并且对合金的拉伸性能、微观组织、断口形貌和夹杂物特征进行了分析,并对其强化机理进行了讨论。发现该合金为奥氏体-铁素体双相组织,其抗拉强度为856.2MPa,伸长率为52.3%,强塑积为44.78GPa·%。并且在拉伸后的样品中发现了变形孪晶,其强化机理为孪晶诱导塑性(TWIP)效应。
In order to study alloys with higher aluminium and silicon mass percent,an alloy with high manganese and high aluminum mass percent was melted using vacuum induction furnace.The tensile property,microstructure,fracture morphology and inclusion characteristics of the alloy were analyzed.The strengthening mechanism of the alloy was discussed as well.It was found that the microstructure of the alloy was austenite-ferrite dual-phase,the tensile strength was 856.2 MPa,the elongation rate was 52.3%,and the product of tensile strength and ductility was44.78 GPa·%.After tensile test,deformation twins was detected in the sample,and the strengthening mechanism is supposed as the TWIP effect.
