At 973K the diffusion coef-ficient of La in liquid Al-5.2-wt%Si alloy D(L_La(Al-s?)) equals (0.91±0.01)×10~(-5)cm.s~(-1). In the range of temperature 953--1053K, the relationship between diffusioncoefficients and temperature is represented by lgD_(La(Al-Sl))=-1.78×10~(-3)-4909/T.The activation energy Q=94.00kJ.mol~(-1). Using the diffuaion data of La, Sr, the in-fluence of the diffusion of modificator on the incubation period of modificationeffect and critical cooling rate has been discussed. Key words:  Diffusion coefficient      activation energy      La      Al-Si alloy      Received:  18 February 1989      Service E-mail this article Add to citation manager E-mail Alert RSS （） Articles by authors URL:  https://www.ams.org.cn/EN/     OR     https://www.ams.org.cn/EN/Y1989/V25/I2/104 1 张启运,郑朝贵,韩万书,金属学报,1981:17:130 2 Sharan R, Anantharaman T R.
