通过将淬火后的１５ＣｒＭｎＭｏＶ 钢进行多道次冷轧的方法制备了金属内生复合板，透射电镜（ＴＥＭ）及Ｘ 射线（Ｘｒａｙ） 衍射研究发现：复合板显微组织呈现明显的层片状特征，试样的屈服强度σ０．２ 为１ ５００ ～１ ８００ＭＰａ，断裂韧性ＫＩＣ为８５ ～１１０ ＭＰａ ｍ１／２ ，ＫＩＳＣＣ为７５ ～９８ ＭＰａ ｍ１／２ 。
Through the multi-pass cold rolling of the quenched 15CrMnMoV steel, the metal endogenous composite plate, TEM and X-ray diffraction were used to study the microstructure of the composite plate. The yield strength σ 0.2 of the sample is 1 500 ~ 1 800 MPa, the fracture toughness KIC is 85 ~ 110 MPa m 1/2 and the KISCC 75 ~ 98 MPa m 1/2.
