合金丝马氏体逆相变的影响 - The effects of baking temperature , baking time and prestrain on the bake hardenability and dent resistance of isotropic sheet steel and bh sheet steel produced by batch annealing were studied
摘要研究了烘烤温度、烘烤时间和预拉伸应变量对罩式炉退火工艺生产的各向同性钢的烘烤硬化性的影响，并与力学性能相当的冷轧烘烤硬化钢进行了对比。 - Comparing with these several strengthen formal , towards strength limit ' s improvement , the effect of torsion - tension and tension - torsion - tension was close ; simply tension - torsion - tension required a little larger prestrain quantity . whereas , towards yield limit " s improvement , the effect of torsion - tension - tension action ' s strengthen was the best
从几种硬化形式的比较来看，对于强度极限的提高，扭转-拉伸和拉伸-扭转-拉伸的强化效果相近，只是拉伸-扭转-拉伸所需的预应变量要大一些；而对于屈服极限的提高，扭转-拉伸-拉伸作用下的强化效果最佳。 - After pretorsion the successor tensile yield limit and strength limit both improved very highly , but the trend of the increase of the strength limit was suspended till the pretorsional capacity reached 17 , when the pretorsional capacity was greater than17 ( prestrain value was 81 . 19 % of total strain ) , the successor strength limit rapid failed and approached the yield limit . this illustrate the a3 steel specimen translate from plasticity into friability after pretorsion strengthen . when the specimen was operated by tension - torsion action , the yield limit had very large improved , but the strength limit changed very little . furthermore , the trend of the increase of the strength limit was suspended till the pretension capacity reached 0 . 25 ( prestrain value was 66 . 93 % of total strain )
A3钢试件在预扭转后，后继拉伸屈服极限和强度极限均有很大提高，但强度极限的增大趋势到预扭转量为17为止，预扭转量大于17 (预应变值为总应变的81 . 19 )后强度极限迅速下降，与其屈服极限接近，这说明a3钢试件经预扭转强化后逐渐由塑性转化为脆性。该预应变值为a3钢试件的韧脆转变点。 a3钢试件在拉伸-扭转作用下，屈服极限有很大提高，但强度极限没有多大改变，而且，屈服极限的增大趋势到预拉伸量为0 . 25应变(预应变量为总应变量的66 . 93 )后就不再增加。 - Consider the total plasticity of these several kinds of prestrain a3 steel specimen . the total plasticity of tension - torsion - tension action was higher than that of torsion - tension and torsion - tension - tension action . but the max . values of their total plasticity were all greater than those of any single destructional form
考虑几种预应变下的a3钢试件的总塑性，拉伸-扭转-拉伸作用下的总塑性比扭转-拉伸和扭转-拉伸-拉伸作用下的总塑性有明显的提高。但它们的总塑性的最大值都大于单一破坏形式下的总塑性。
