%X The cleavage fracture mechanism of acicular bainitic weld metal in steel 15MVN has been investigated, SEM observation of a special specimen for re- vealing simultaneously fracture surface and microstructure shows that the cleavage of the weld metal is initiated by M-A constituent. The 95th percentile equivalent diameter of M-A constituent controlls the cleavage fracture stress of the weld me- tal.
