The kinetics of decomposition of retained austenite in AISI 4325,AISI 4340and their silicon modified steels has been studied by precision length measurement.It is found that the internal stresses play a very important role in the first instantof transformation.In steels with normal silicon content(0.2—0.3%),the activation energy of thedecomposition of retained austenite is about 35,000 cal/mole,comparable to thatrequired for the diffusion of carbon in γ-Fe.In general,high silicon content(1.5% Si)retards...

The kinetics of decomposition of retained austenite in AISI 4325,AISI 4340and their silicon modified steels has been studied by precision length measurement.It is found that the internal stresses play a very important role in the first instantof transformation.In steels with normal silicon content(0.2—0.3%),the activation energy of thedecomposition of retained austenite is about 35,000 cal/mole,comparable to thatrequired for the diffusion of carbon in γ-Fe.In general,high silicon content(1.5% Si)retards the transformation of retain-ed austenite in these steels.Based upon the isothermal transformation curvesand rate equation the activation energy for this transformation has been deter-mined to be about 44,000 cal/mole,and it is therefore suggested that the diffusionof silicon in γ-Fe surrounding the growing carbide particles is possibly the ratecontrolling factor.

用测量长度的变化,得出残留奥氏体在含硅量不同的Ni(2%)Cr(0.8%)Mo(0.25%)高强度低合金钢中在回火过程的分解曲线,在这些合金钢中,硅的含量为1.5%时,残留奥氏体的分解较慢。由其分解激活能的推论得到:在这个类型的合金钢中,含硅量较低时(0.2—0.3%),残留奥氏体的分解是由于碳在奥氏体中的扩散,而含硅量较高时(1.5%),硅的扩散可能成为残留奥氏体分解的控制因素。

The kinetics of decomposition of 3, 5, 5-trimethylhexanoyl peroxide (1) in benzene has been studied at 30, 40 and 50℃ and the cage effect of decomposition has been determined by scavenging method. The relative amounts of the main products of decomposition of 1 at 50℃ with change of initial concentration have been determined. The results showed that the decomposition of 1 followed first plus three halves order kinetics as reported for lauroyl peroxide (2), but had a larger cage effect of 0.6. The mechanism of decomposition of 1 is practically the same as what we have proposed for 2. The faster rate and larger cage effect but less induced decomposition of 1 than that of 2 are attributed to the branching of the molecule of 1, especially to the presence of β-methyl group, which causes a larger entropy increase in the transition state.

本文对过氧化3,5,5-三甲基己酰(1)在30,40,50℃苯中的分解动力学、笼效应、分解主要产物及用galvinoxyl(3)捕获的产物进行了测定。结果表明,当起始浓度在0.04到0.43mol.L~(-1)范围内时,1在苯中的分解符合一级加二分之三级动力学;笼效应为0.6;也基本上符合作者以前提出的过氧化月桂酰(2)在苯中的分解机理。与2相比,1在同样温度下的自发分解有较大的速率、较大的笼效应以及较少的诱导分解,这应归因于1分子内的枝化,尤其是β-甲基的存在,引起的分解反应物与过渡态之间的较大熵增。

Recently, thermal analysis is a useful technique to study the kinetics of decomposition reaction. We used this technique to studythree kinds of organophosphorus pesticides--roger, dipterex andparathion-methyl and obtained kinetic equations of the theremal decomposition.These pesticides may decompose more or less readily in storage conditions. The rate of decomposition increases at higher temperature, especially to parathion-methyl, and an explosive violence would occur at certain temperature.In...

Recently, thermal analysis is a useful technique to study the kinetics of decomposition reaction. We used this technique to studythree kinds of organophosphorus pesticides--roger, dipterex andparathion-methyl and obtained kinetic equations of the theremal decomposition.These pesticides may decompose more or less readily in storage conditions. The rate of decomposition increases at higher temperature, especially to parathion-methyl, and an explosive violence would occur at certain temperature.In order to control the thermal decompositions of these pesticides either in storage or in production, we studied their decomposition kinetics and mechanisms and estimated the "stable life" at some lower temperature.
