specific strength, high specific stiffness, and many other advantages (Mordike et al., 2001). With the increased consciousness of energy saving and environmental protection, Mg alloys are becoming widely recognized as the candidates to replace steel and aluminium alloys in many fields, such as in vehicles and the electronics industry. Mg alloys are thus becoming known as new ‘green’ engineering...

Flow curves are generated in muti-pass torsion tests for a titanium stabilized and a niobium stabilized IF steel. Two types of test schedule are used, one based on plate rolling and the other approximating strip rolling. The purpose of the former is to define the three critical temperatures of steel rolling. The strip schedules are varied in order to investigate the influence of increasing the ...

While the navigation metaphor has received widespread support from the HCI community, the views on the usefulness of the navigation approach have a very wide range. Benyon (1998, p 35) argues that “‘Navigation in Information Space’ is not (just) a metaphor, (...) [it] is a new paradigm for thinking about HCI.” On the other hand, Dillon and Vaughan (1997) claim that “navigation is a limited meta...

The final hot strip profile is a superposition of the roll initial crown, the roll bending and flattening crown, the roll wearing crown and the roll thermal crown. In this research, linear regression models are proposed to predict the roll force, the roll wearing crown and the roll thermal crown using experimental data provided by Mobarake Steel Complex (MSC). The short beam theory based on ela...

In this paper, the deformation and phase transformation of disordered α in (α + γ) two-phase region as-forged Ti-44Al-8Nb-(W, B, Y) alloy were investigated by hot-compression hot-packed rolling. The detailed microstructural evolution demonstrated that deformed microstructure was significantly affected conditions, differences mainly due to use a lower temperature strain rate. Finer grains formed...
