Based on the test prepared by powder metallurgy TZM alloy sintered and then rolled into 2mm thick plate,the four times rolling compound for TZM plate by accumulative roll bonding technology (ARB) was successfully completed.And the properties tests and structural analysis of different times of TZM composite board was made.The results show that:with cumulative deformation increasing,the grain is refined,and the tissue is distributed homogeneously.The tensile strength and interface state are the best after the three time cumulative compound.During rolling process,the grain size of the sample is elongated and broadened,the grain section diameter is 200-500nm,tensile strength increases by 50％,the maximum tensile strength of 2mmTZM composite board reaches 968 MPa; but its fracture feature is a brittle fracture,elongation rate does not change obviously,and the elongation rate of the composite plate is only 2％.%采用粉末冶金法制备出TZM合金烧结坯,并将其轧制成2mm厚板材,在此基础上采用累积复合轧制技术(ARB),完成TZM板四次轧制复合,并对不同道次TZM复合板进行性能测试和组织分析.结果表明:随累积变形量增加,复合板晶粒显著细化、组织分布更加均匀,经过三次累积复合后,材料的抗拉强度和界面结合状态最佳.试样晶粒在轧制过程中被拉长、展宽,晶粒断面直径200～500nm,抗拉强度提高50％,2mm TZM复合板最高抗拉强度可达968MPa;材料断裂特征仍为脆性断裂,伸长率变化不明显,轧制复合板伸长率仅为2.0％.
