%X The influence of two different grain shapes and carbides in the HK40 alloy,the material for use of furnace tube, on the rate of creep crack growth has been investigated.The material of columnar grain is inferior resistance against creep crack growth to that ofequiaxial grain, when the load line is perpendicular to the columnar grain axis. The influenceof secondary carbides on the rate of creep crack propagation is dependent upon the grain shape.
