Abstract CERROCAST Alloy is a non-eutectic alloy with a melting range from 281 F to 338 F. It provides manufacturing engineers with an easily castable material that is ready for use soon after it freezes; moreover, it can be recovered readily and recycled into new uses any number of times. Cerrocast alloy is used widely for spray molding techniques, for sealing and soldering in low-temperature work, for proof casting in foundries and for masks in spray painting and electroplating. This datasheet provides information on composition, physical properties, hardness, and tensile properties. It also includes information on heat treating, machining, and joining. Filing Code: Sn-9. Producer or source: Cerro Metal Products.

Increased Strength

Gradient nanotwinned (GNT) metals exhibit extra strengthening and work hardening behaviors, which endow them impressive potentials in engineering applications. The increased strength is attributed to the dense interactions between dislocations and boundaries in the grain interiors. However, a constitutive model elucidating the extra strengthening effect is currently lacking. Here, we propose a theoretical framework to describe the mechanical response of GNT metals, especially the unusual extra strengthening behavior. The model captures the deformation mechanisms of GNT metals and coincides well with the reported experiment. The constitutive description developed in this work presents a tool to guide the structural design for developing gradient metallic materials.

The ubiquity of aircraft in being and yet to be, whether civil or military, manned or unmanned, makes them liable to exposure to wide extremes of atmospheric conditions. The range of temperature to which they may be subjected may possibly be from +90° to –90°C. (+194° to –130°F.), that of pressure, from one atmosphere to something approximating to one-tenth of this amount, while the water content (aqueous vapour plus water in suspension; for example, in a very dense tropical cloud), can, on occasion, be as high as 2.5 per cent. by weight and, at stratospheric heights, at least as low as 0.001 per cent. Such variations in ambient conditions are not without chemical and physical repercussions. The engineering problems which arise will be examined, therefore, from both these view points, and attention will be drawn to potential dangers and means suggested for their avoidance.
