The effect of micro parameters of martensite ( M ), bainite ferrite ( BF ), ferrite ( F ) and retained austenite ( γ R) multiphase mixed structure on strength and ductility was investigated. The results showed that yield strength of fibrous multiphase mixed structure was related to strengthening state and quantity of movable dislocation in ferrite. The ultimate strength was dominated by the volume fraction of high strength phase ( M+BF ), especially martensite and its strength, while the ductility was related to the length of fiber F , the volume fraction of γ R, and differences of strength among phases. The best balance of strength and ductility was obtained by heat treatment of 1 050 ℃ prequenching +760 ℃ intercritical heating +400 ℃ short time holding. The maximum value of ( σ b· δ 5) reached 33 561 MPa·%, much higher than that of massive mixed structure.

研究了30CrMnSiA钢中马氏体(M)+贝氏体铁素体(BF)+铁素体(F)+残留奥氏体(γR)多相复合组织形态、微观参量对强塑性的影响。研究结果表明,纤维状多相复合组织的屈服强度与F的强化状况及可动位错数量有关。极限强度主要受控于高强度相(M+BF),尤其是M量及其强度,而塑性则与F纤维长度、γR量及各相强度差大小有关。采用1050℃预淬火+760℃临界区加热+400℃短时等温热处理,可以获得最佳的强塑性配合,并且最高强塑性积(σb·δ5)可达33561MPa·%,远高于块状复合组织。

>=Brake friction heat is the key factor that influences the safety and reliability of braking. Based on the analyses of the production, distribution and transformation of the brake friction heat, the actual conditions are simulated by the finite element method and the temperature dynamic distributions on the heat-affected layer of the multiphase mix-structures of the friction brake material calculated. Furthermore, with the analyses of the components and structure of the heat-affected layer, the specialties of the influence of the multiphase mix-structure of the composite to the brake friction heat and braking properties have been studied. The relevant results would be helpful to provide the theory base for the friction properties controlling of the brake and the development of new high performance friction materials.
