The effects of alloying elements Cr, Mo and Si in austenitic cast iron with a 20%nickel content on its resistance to thermal shock and the relationship between the morphology of graphite and carbide and the crack extension type and its speed due to thermal shock are discussed. For spheroidal graphite iron, it has been found that the crack due to thermal shock is a grain boundary one and its resistance to thermal shock is the highest. For lamellar graphite iron, the crack is a transgranular one and the resistance to thermal shock is the lowest. For dendritic graphite iron, the crack is a hybrid one and the resistance is between those of spheroidal and lamellar graphite irons. The resistance can be significantly improved with suitable contents of Cr, Mo and Si in the spheroidal austenitic cast irons.

本文论述了合金元素Si,Cr,Mo对含Ni20%的高镍奥氏体球墨铸铁抗热冲击性能的影响,揭示了石墨和碳化物形态与热冲击疲劳裂纹扩展方式和扩展速率之间的关系。发现石墨呈球状时热冲击疲劳裂纹为晶界型裂纹,抗热冲击性能最好;呈片状时为穿晶型裂纹,抗热冲击性能最差,呈枝晶状时为(晶界加穿晶)混合型裂纹,抗热冲击性能介于前二者之间.加入适量的Cr,Mo,Si可显著地提高抗热冲击性能。

The thermal shock fatigue behavior of Ti(C,N) based ceramets containing 20% nickel has been studied The results show that the formation of thermal shock fatigue cracking is related to the nucleation, growth and joining of microvoids distributed at the interfaces of Ti(C,N)/Ni phases The incubation period of crack formation decreases and the rate of crack propagation increases with increasing cyclic temperature and cooling rate within the cycles The effects are mainly caused by increases of thermal stress...

The thermal shock fatigue behavior of Ti(C,N) based ceramets containing 20% nickel has been studied The results show that the formation of thermal shock fatigue cracking is related to the nucleation, growth and joining of microvoids distributed at the interfaces of Ti(C,N)/Ni phases The incubation period of crack formation decreases and the rate of crack propagation increases with increasing cyclic temperature and cooling rate within the cycles The effects are mainly caused by increases of thermal stress and temperature gradients within the specimens The introduction of a notch also has the same effect SEM examination has some striae on the thermal shock fatigue fracture surfaces The crack propagation is a continuous process on a macroscopic scale although discontinuous microscopically

研究了含20%Ni的Ti(C,N)基金属陶瓷的热冲击疲劳。试验结果表明:随循环温度的上升和冷却速率的加快,热冲击疲劳裂纹的形成孕育期缩短,裂纹扩展速率加快。缺口也使裂纹形成的孕育期缩短。观察还表明,热冲击疲劳断口中存在疲劳条纹。

The formative mechanism of thermal shock fatigue crack of cemented carbide YG8 has been investigated. Results have shown that the formative mechanism of the crack is related to the nucleation,growth and join of microvoids distributed at the interfaces of WC/Co phases. A dislocation model of describing the nucleation and growth of microvoid also has been proposed

研究了YG8硬质合金热冲击疲劳裂纹的萌生机制。试验结果表明,热冲击疲劳裂纹的萌生与WC/Co相界面微孔洞的形核、长大和连通有关。文中还提出了微孔洞形核和长大的位错模型。
