摘要：

<正>In this paper,the influence of preheating on the layer microstructure and properties is analyzed in the layermetal microstructure.The influence of preheating temperature on the shape and amount of primary crbides and bordeslittle,but on initial γ-dendrites is large With the increasing of preheating temperature,little by little the γ-dendrites,which grown from parent mateiol to layer,are flourishing to disappearing,and the microhardness at the center of the layer is increasing.
