Through thermal simulation compression experiment of tank used aluminium alloy,the influence of rate of deformation and deformation temperature on rheological stress were analyzed.
通过对罐用铝合金进行热模拟压缩实验,分析了变形速率、变形温度等参数对流变应力的影响,计算出了该合金的材料常数,并建立了该合金稳态流变应力模型。
20/s and at constant temperature in the range of 450～500 ℃ were conducted on the 35steel and 45steel on the basis of the rheological stress constitutive model of 20steel.
为了进一步研究温度和应变速率对固体金属材料的粘性性质及其流变力学特性的影响,在建立20号钢的高温流变应力模型的基础上又对35号、45号碳素钢在温度为450~550℃和等应变速率(0。
The experimental results indicated that the rheological stress was influenced by both strain rates and deformation temperature,and it increased with increasing strain and tends to be constant afte.
采用圆柱试样在Gleeble-1500热/力模拟试验机上进行高温压缩变形试验,研究了2124铝合金在高温塑性变形过程中流变应力的变化规律。
