Effects of Austenizing Time on Wear Behavior of D6 Tool Steel After Deep Cryogenic Treatment

The effects of the prior austenite grain size in deep cryogenic treatment on the hardness, the structural change and the wear resistance of D6 tool steel were investigated. The wear resistance of the cryogenically treated samples was determined using the pin-on-disk wear machine. The microstructural characteristics and phases present in heat treated samples were determined using SEM and XRD techniques. The results showed that the retained austenite is completely transformed to martensite during the cryogenic treatment. Besides, there is an optimum grain size of which the maximum wear resistance and hardness are obtained.

Effects of Austenizing Temperature on Reprecipitation of BN

Most of BN was precipitated around the spherical MnS and formed the compound of MnS and BN during the isothermal treatment at 850 ℃ after austenizing at 950-1050 ℃. Most of MnS was transformed into polygon when austenized at 1 150 ℃ or above, which could not be the nuclei of BN anymore. During the insulation process at 850 ℃, MnS kept the state of monomer. The compound of MnS and BN at earlier time was of fine polycrystalline in spherality and BN was formed as a plate-like monocrystal on a certain part of the polycrystalline when its dimension reached 0.6 μm.

两个务实的人中间的务实婚姻 --析《傲慢与偏见》(英文)

Jane Austen begins Pride and Prejudice with "It is a truth universally acknowledged that, a single man in possession of a good fortune, must be in want of a wife."Hence, there is no doubt that marriage will be a central concern of Pride and Prejudice. In this novel, Austen depicted several types of marriage: Elizabeth and Darcy’s marriage which emphasized equality and independence, Jane and Bingley’s marriage for love’s sake, Charlotte Lucas and Mr. Collins’ practical marriage and the rash marriage between Lydia and Wickham. This thesis is focused on the practical marriage between Charlotte Lucas and Mr. Collins while further explores the reasons behind their pragmatism.

A Study of Romantic Tendency in Jane Austen's works——A Comparison between Sense and Sensibility and Persuasion

Sense and Sensibility and Persuasion is Jane Austen's first and last published works respectively, which are read widely all over the world. Austen proclaims that feeling should be governed by reason in Sense and Sensibility and that reason should be compatible with feeling in Persuasion. This paper attempts to explore romantic tendency in Austen's works according to the comparison and contrast between her two novels. Through comparison and contrast, we can see the transformation of Marianne from a lady of sensibility to a sensible lady and the growth of Anne into a lady with romance.

Effect of continuous annealing parameters on the mechanical properties and microstructures of a cold rolled dual phase steel

A cold rolled dual phase （DP） steel with the C-Si-Mn alloy system was trial-produced in the laboratory, utilizing a Gleeble-3800 thermal simulator. The effects of continuous annealing parameters on the mechanical properties and microstructures of the DP steel were investigated by mechanical testing and microstructure observation. The results show that soaking between 760 and 820℃ for more than 80 s, rapid cooling at the rate of more than 30℃/s from the quenching temperature between 620 and 680℃, and overaging lower than 300℃ are beneficial for the mechanical properties of DP steels. An appropriate proportion of the two phases is one of the key factors for the favorable properties of DP steels. If the volume fraction of martensite and, thereby, free dislocations are deficient, the tensile strength and n value of DP steels will decrease, whereas, the yield strength will increase. But if the volume fraction of martensite is excessive to make it become a dominant phase, the yield and tensile strength will increase, whereas, the elongation will decrease obviously. When rapid cooling rate is not fast enough, pearlite or cementite will appear, which will degrade the mechanical properties. Even though martensite is sufficient, if it is decomposed in high temperature tempering, the properties will he unsatisfied.

Imperfect Emma:An Analysis of Emma's Character Flaws

Influence of austenization temperature on the erosion behavior of austempered ductile irons

The erosion behavior of austempered ductile irons austenized at different temperatures was studied. The results indicate that the erosion rate well correlates with the mechanical properties. At high impact angles, increasing ductility and mechanical energy density results in decreasing erosion rate, whereas increasing hardness reduces the erosion rate at low impact angles. 2008 University of Science and Technology Beijing.

EFFECT OF ELECTRIC FIELD ON THE AUSTENIZATION OF A LOW CARBON STEEL

With an electric field during austenitizing, the martensite transformation of the low carbon steel was promoted, and more martensite were obtained. The electric field promotes the homogeneity of carbon, and reduces the free energy of austenite. The critical neuclus r* and the critical driving force G* responsible for the nucleation of proeutectoid ferrite were increased. As a result of which the diffusion controlled proeuctoid ferrite transformation was retarded and the hardenability was improved.

“Thou hast thy music too”:The Autumnal Duet in Jane Austen's Persuasion

Jane Austen's posthumously published novel Persuasion has been regarded as a foreshadowing of Romanticism, especially in its autumnal tone that has inherent intimacy with John Keats's To Autumn and Percy Bysshe Shelley's Ode to the West Wind. Blending the stylistic disparities in the two Romanticist poems, Persuasion 's autumnal sensation changes its colors from being tinged with Keats's melancholy to the touch of Shelley's animation. The integration of both tones has created a unique autumnal duet that is remindful of its Romanticist followers.

Mistress of the House——An Interpretation of Emma and Her Predicament in Jane Austen's Novel Emma

Published in 1815, Emma is considered to be Jane Austen's best and most representative novel. It tells the story of how the heroine acquires the knowledge of herself as well as the world, and finally steps to maturity. Attracting readers with its humor and vivacity, the novel, at the same time, repeatedly betrays a sense of frustration and incompleteness. Looking into Emma's role in the family, her moral judgment, and her relationships with male characters in the novel, we will be able to touch the root of her power, yearning and predicament. My paper attempts to explore into the above three aspects in order to discover the inherent ironies of the novel and Austen's profound reflections on the position of women.
