The results show that the alloy undergoes obvious plastic elongation, the specimen fractures into four sections and the diameter changes from 16 mm to 12 mm. The fracture surfaces distribute randomly well developed and partially developed veinal patterns. The deformation behavior of alloy is non-Newtonian flow behavior. About 3% amorphous matrix of extruded specimen transforms crystal, the crystal particles with size of 10-20 mm are precipitated in the amorphous matrix, the thermostability of the extruded specimen was lowered. The failure of the alloy is mainly attributed to non-uniform viscous flow under high strain rate resulting from the hydrostatic extrusion process.
结果表明:非晶合金在高应变速率下产生了明显的塑性变形,直径从16 mm变为12 mm,断裂为4段,且样品断口上随机分布着充分发展与未充分发展的脉纹式切变带,由此可看出非晶合金的变形为非牛顿体变形行为;挤压后的样品约有3%的非晶相发生晶化,在非晶基体上析出10~20 nm的纳米晶粒,导致挤压后非晶合金的热稳定性降低;静液挤压高应变速率变形条件使非晶合金产生非均匀流变,是造成非晶合金断裂的主要原因。

Increased spin disorder and a decrease of with increasing Fe content are evident. It depopulates the hopping electrons and weakens the double exchange. From resistivity and magnetization data, it is expected that the addition of Fe can introduce grain boundaries and form antiferromagnetic clusters.
电阻率的峰值随着Fe的增加而增大,并且峰值对应的温度TIM向低温移动,随着外加磁场的增大电阻下降,产生MR效应,这是因为随着掺杂的增加,自旋无序增加,外场的增加抑制了自旋的扰动,在顺磁温区内,电子自旋形成了随机的磁结构,产生电子局域,破坏了极化子形成的环境,因此输运机制由绝热极化子输运转变为变程跳跃机制。

In chapter three the performance and structure of components of oxygen probe were especially investigated. The Cr-Cr〓O〓 powder was overcome by treatments. The reason of occurrence of thermal peaks on the EMF curves was explained. A water glass based cement which high temperature insulation was around 10MΩ within 10 seconds at 1600℃ was developed for the use of oxygen probe. The effects of tip end thickness of ZrO〓 tube and amount of reference electrode on response time and thermal equilibrium in oxygen probe were investigated. The optimum tip end thickness of ZrO〓 tube and amount of reference electrode addition were determined. It is found that the heat transfer in oxygen galvanic cell is the rate limiting-step in the response process. The national oxygen probe WOS Ⅱ type was designed and manufactured. By three batches of industrial tests its specification reached the level of American Celox Ⅱ type oxygen probe.
