摘要
作者用不同壁厚和重量的圆柱形铝合金铸造试块进行了固溶时效处理对其组织（DendriteArmSpacing，即树枝晶干间距，简称D．A．S）和机械强度影响的试验。结果表明，AC4B铝合金铸件的D．A．S和机械强度的尺寸效应表现为铸件模量（体积与表面积的比值，即V／S）的函数；对经过T6热处理的试块，所测出的尺寸效应也保持为铸件模量的函数关系。
The authors have made experiments,using specimens of cylindrical casting different in thickness and mass,on the influence of solution treatment upon the mechani cal strength and structure(D. A. S)of the said casting. Since the mass effect of mechanical strength and D. A. S length of AC4B casting are considered to be a function of casting modulus,and the relationship among them in the specimens subjected to solution treat ment T6 was examined with mass effect are considered to be also a function of casting modulus.
