Current experimental investigation deals with the effects of asymmetrical rolling parameters on the inhomogeneity, microstructure, mechanical, and geometrical properties of rolled brass wire. Toward this end, a roll machine with three different roll radii ratios was set up. The asymmetrical conditions are arranged using three different sets of rolls with different diameters that result into dif...

We present results from a systematic study linking material microstructure to monotonic and fatigue properties of NiTi shape memory alloys. We consider Ni-rich materials that are either (1) hot rolled or (2) hot rolled and cold drawn. In addition to the two material processing routes, heat treatments are used to systematically alter material microstructure giving rise to a broad range of therma...

This work examines the effect of heat treatment on tensile strength and ductile responses of rolled and forged AA6063 aluminum alloy. Some cast samples were rolled while some were forged at ambient temperature (32C). The deformed samples were subjected to heat treatment processes. The tensile strengths of rolled (212 MPa) and forged (127 MPa) samples are enhanced at ambient temperature but with...

Oat is promoted as a low-glycaemic index food. Our aim was to measure the effect of the fat content of oat in glycaemia and insulinaemia and compare it with the effect of wheat. The study design was a double-blind, randomised cross-over study with four treatment segments. Eight healthy males attended four study sessions in which porridge made from four different raw materials was consumed: roll...

Tensile and fatigue properties of as-rolled and annealed polycrystalline Cu foils with different thicknesses at micrometer scale are investigated. Uniaxial tensile testing shows that with decreasing foil thickness the uniform elongation decreases for both as-rolled and annealed foils, while the yield strength and ultimate tensile strength increase for as-rolled foils, but those decrease for the...

folded bandage102919 significantly different for folded and for rolled bandages (long, p < 0.001 and short p <0.01). Discussion. This study has confirmed that Esmarch bandages, whether tightly rolled or loosely folded, may not be properly sterilised by normal autoclaving and that there is a significant difference between the rolled and folded group. The causeoffailure is probably the thermal in...

Hetero-yellow (Hu red (RED) and brown (BR, high tannin) sorghums were fed dry-rolled or reconstituted (RED and BR only) to evaluate the effect of variety and reconstitution on the site and extent of starch and protein digestion in steers fitted with ruminal, duodenal and ileal cannulae. Processed grains were incorporated into 88% sorghum (DM basis) diets fed at 2% of body weight in a 5 • 5 Lati...

Cold rolling behaviours of a commercial pure titanium have been studied by means of transmission electron microscopy. The results indicates: (1) In cold rolled titanium, there are a number of tangled dislocations which have often been observed in cold worked face centered cubic metals. (2) In 16.7% cold rolled Ti, imperfect structures with a high concentration of tangled dislocations were obser...

the formation of nano/ultrafine grained ferrite in low carbon steels containing different amounts of niobiumwas investigated using thermomechanical treatment which consisted of annealing of 85% cold rolled martensite with different parameters. the specimens were characterized by optical and scanning electron microscopy and vickers hardness test. a lamellar dislocation cell structure was formed ...

In distributed applications, a group of multiple objects are cooperated to achieve some objectives. The objects may su er from kinds of faults. If some object o is faulty, o is rolled back to the checkpoint and objects which have received messages from o are also required to be rolled back. In this paper, on the basis of the message semantics, we de ne in uential messages whose receivers are re...
