In order to probe the existence of nonthermal microwave effects, four synthetic transformations (Diels-Alder cycloaddition, alkylation of triphenylphosphine and 1,2,4-triazole, direct amide bond formation) were reevaluated under both microwave dielectric heating and conventional thermal heating.

为了探测非能微波效应的存在,四种合成转化反应(Diels-Alder环加成、三苯基膦和1,2,4-三唑的烷基化、酰胺键的直接合成)在微波介电加热和传统热加热两种情况下的重新评价。

Underfill technology has been used to minimize the mismatch of the Coefficient of Thermal Expansion in flip chip technology.

Meanwhile, amorphization induced by ion mixing, beginning also with multilayered films, has been extensively studied since early 1980s and some scientists have argued that a positive heat of formation is unfavored for amorphous alloy formation.

同时,80年代初以来,人们也对多层膜离子束混合诱发非晶化开展了广泛的研究。一些学者认为正的生成热不利于非晶态合金的形成。

Based on the design of the interfacial free energy, the positive heat of formation, which is an unfavored factor for alloying, could be overcome for forming amorphous alloys in those equilibrium immiscible binary metal systems, thus confirming the thermodynamic model for metallic glass formation proposed previously by this research group.

二、通过界面能的设计可以克服正生成热的不利影响而制备出非晶态合金,论证了本研究组提出的非晶化相变的热力学模型的合理性。

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。
