The continuous cooling transformation curves of Zr- and Pd-based alloys are calculated and the results are in good agreement with the experimental values. It is suggested that the method can be used to evaluate glass forming ability of alloy systems more effectively. In addition, the calculation results show that the main factors effecting the critical cooling rate are the viscosity of melt, nucleation barrier and critical volume fraction of the crystal, the critical cooling rate is reduced with the increase of the viscosity, nucleation barrier and critical volume fraction of crystal.","authors":[],"categoryName":"|","doi":"","fpage":"1953","id":"430eb4b5-d965-40f8-b498-4f445b8aa2e0","issue":"4","journal":{"abbrevTitle":"APS","id":"36b887b6-8083-4722-8735-38a6f6f18130","issnPpub":"1000-3290","publisherId":"APS","title":"Acta Physica Sinica"},"keywords":[{"id":"c3a4e4f0-31ee-4a5d-ae0f-92e85ce1d45b","keyword":"critical cooling rate;glass forming ability;bulk metallic glass;continuous cooling transformation curve;alloys;stability","originalKeyword":"critical cooling rate;glass forming ability;bulk metallic glass;continuous cooling transformation curve;alloys;stability"}],"language":"en","publisherId":"1000-3290_2006_4_1","title":"A new model for calculating the critical cooling rate of bulk metallic glass under non-isothermal condition","volume":"55","year":"2006"},{"abstractinfo":"介绍了在不同性质应力(拉应力或压应力)作用下氧化\n膜开裂和剥落的方式和特点及发生开裂和剥落的临界温度变化条件.简述了在外加应力作用下氧化膜的破裂行为及改善氧化膜力学完整性的主要方法.","authors":[{"authorName":"钱余海","id":"144492f2-6aec-4ec8-a6ed-ea535cde151f","originalAuthorName":"钱余海"},{"authorName":"李美栓","id":"b5ec038f-015e-4941-8561-c5e33dda86c0","originalAuthorName":"李美栓"},{"authorName":"张亚明","id":"e213d141-c00b-4d5d-9bce-620006e1ac14","originalAuthorName":"张亚明"}],"categoryName":"|","doi":"","fpage":"90","id":"f2585668-272e-4885-b80b-ef346feae824","issue":"2","journal":{"abbrevTitle":"FSXB","coverImgSrc":"journal/img/cover/腐蚀学报封面.jpg","id":"24","issnPpub":"2667-2669","publisherId":"FSXB","title":"腐蚀学报(英文)"},"keywords":[{"id":"d977a455-00dd-452d-b717-168fb86b8261","keyword":"氧化膜","originalKeyword":"氧化膜"},{"id":"b573efe0-9ba6-4025-bf9a-099398742780","keyword":"cracking and spalling","originalKeyword":"cracking and spalling"},{"id":"30a4f0f9-87e8-4bd6-8e1e-6d16ff80b17c","keyword":"critical condition","originalKeyword":"critical condition"}],"language":"zh","publisherId":"1002-6495_2003_2_4","title":"氧化膜开裂和剥落行为","volume":"15","year":"2003"},{"abstractinfo":"The surface oxidation patterns of iron or low-carbon steels are critical to their life when serving in typical damp environments. An accurate determination of the oxidation pattern entails tracking the iron atoms oxidized at the iron/steel-moisture interface. Using a quantum chemistry-based force field that is capable of simulating chemical reactions, this paper studies the process of iron oxidation under a typical moist condition. The oxidation of iron surface was found to be highly thermodynamic and dependent on the availability of reactants. A triplex structure was formed at the end of a three-stage oxidation process to reduce the overall oxidation speed. The results from this study shed light on the atomistic mechanism of iron oxidation; therefore can be used to guide the protection of general ferrous-based iron/steel structures.","authors":[{"authorName":"Tongyan PAN","id":"8090eda8-b5d6-4092-b804-9b876814172f","originalAuthorName":"Tongyan PAN"}],"categoryName":"|","doi":"","fpage":"415","id":"b7f87b92-6fe5-40df-a50c-d4f9ce480c2d","issue":"6","journal":{"abbrevTitle":"JSXBYWB","coverImgSrc":"journal/img/cover/amse.jpg","id":"49","issnPpub":"1006-7191","publisherId":"JSXBYWB","title":"金属学报(英文版)"},"keywords":[{"id":"b667d008-ed14-494b-b8a4-198307a464fe","keyword":"Iron oxidation","originalKeyword":"Iron oxidation"}],"language":"en","publisherId":"1006-7191_2011_6_4","title":"Physicochemical nature of iron oxidation in a damp atmospheric condition","volume":"24","year":"2011"},{"abstractinfo":"Using gauge field theory of defects,the effective critical extension force in elastic-plastic fracture mechanics was given.The rationality of logarithm of effective extension force as a linear function of the fractal dimensionality of the fracture surface was analyzed in theory.

The main feature of the present theory is to find an appropriate starting point for perturbation expansion, which can directly treat the infrared divergences encountered in the conventional perturbation theory. Exact critical conditions for the phase transition of the model are derived; and the quantum sine-Gordon Hamiltonian is found to correspond exactly to a free-field model. Near the critical regime, a gap will open near zero momentum in the excitation spectrum, and the corresponding ground-state wave function is a pairing quasiparticle state, analogous to the BCS superconducting state. It is proved that this ground state will possess quasi-long-range and quasi-off-diagonal long-range correlations. Comparisons with the Kosterlitz-Thouless classical theory of the two-dimensional Coulomb gas are also made.","authors":[],"categoryName":"|","doi":"","fpage":"13566","id":"2d1ff6fb-6fe3-4d37-b8de-18cf8011481f","issue":"16","journal":{"abbrevTitle":"PRB","id":"41d73232-e732-4216-a5f7-4b352bb955cf","issnPpub":"0163-1829","publisherId":"PRB","title":"Physical Review B"},"keywords":[{"id":"9f511443-9509-49a1-8cd0-649fbedf284a","keyword":"2-dimensional coulomb gas;squeezed-state approach;yang-mills theory;superconducting films;phase-transitions;quark confinement;critical-behavior;thirring models;gauge theories;field-theory","originalKeyword":"2-dimensional coulomb gas;squeezed-state approach;yang-mills theory;superconducting films;phase-transitions;quark confinement;critical-behavior;thirring models;gauge theories;field-theory"}],"language":"en","publisherId":"0163-1829_1991_16_1","title":"CRITICAL PROPERTIES OF THE QUANTUM SINE-GORDON EQUATION","volume":"43","year":"1991"},{"abstractinfo":"sWe have developed a mass- and charge-dependent equation to predict theoretical critical angles for ion channeling in carbon nanotubes We focus M (ion mass) effects how to reduce Ze (ion nucleus charge) effects on Psi(c) (critical angles).
