采用Nakazima实验法对不同尺寸的退火态TA2/Q235B复合板样品进行胀形实验,研究不同作用面对TA2/Q235B复合板的成形极限和界面损伤行为的影响.结果表明,当凹模与碳钢侧接触时,由于接触材料、界面变形协调能力和应变状态的不同,复合板的胀形高度和成形极限增加,其中R140试样的极限拱高达到最大值(46.17 mm),R60和R180试样在3个方向上的厚度减薄量和界面裂纹更大.此外,由于硬度和拉应力不同,两组样品中所有的水平和斜向孔都向纯钛侧延伸.
Forming limits and interface damage behavior of different acting surfaces on TA2/Q235B composite plate
The Nakazima method was applied to performing bulging experiments of annealed TA2 pure titanium/Q235B carbon steel composite plate samples with different sizes.The effects of acting surfaces on forming limits and interface damage behavior of TA2/Q235B composite plate were investigated.It is found that when the steel contacts with the concave die,the bulging height and forming limit of the composite plate increase due to the different contact materials,coordination deformation ability of the interface,and strain state.The bulging height of the R1 40 specimen reaches the maximum value(46.17 mm),and the thickness reduction and interfacial crack of the R60 and R180 specimens in three directions are larger.In addition,due to the difference in hardness and tensile stress,all horizontal and inclined holes in both groups extend toward the pure titanium.
