Fluid Metal

In 1879-80 I drew attention to a method of measuring the changes of volume taking place in cast iron while passing through the varying temperatures lying between its cold and its molten state. If a ball of cast iron at atmospheric temperature be immersed in a vessel of molten iron of the same quality, it first sinks. In a few seconds it comes to the surface, owing to the heat penetrating and expanding the ball, which, causing increased displacement of the fluid metal, produces the increased buoyancy observed.

Abstract MEEHANITE-GD is a high strength iron casting having high damping capacity, self-lubricating properties, and good machinability. It combines the good properties of both cast iron and steel. This datasheet provides information on composition, physical properties, hardness, elasticity, tensile properties, and compressive and shear strength as well as fracture toughness and fatigue. It also includes information on casting, heat treating, machining, and joining. Filing Code: CI-32. Producer or source: Meehanite Metal Corporation.

Abstract Drops of molten cast iron were placed on moulding sand substrates. The composition of the forming gaseous atmosphere was examined. It was found that as a result of the cast iron contact with water vapour released from the sand, a significant amount of hydrogen was evolved. In all the examined moulding sands, including sands without carbon, a large amount of CO was formed. The source of carbon monoxide was carbon present in cast iron. In the case of bentonite moulding sand with seacoal and sand bonded with furan resin, in the composition of the gases, the trace amounts of hydrocarbons, i.e. benzene, toluene, styrene and naphthalene (BTX), appeared. As the formed studies indicate much higher content of BTX at lower temperature it was concluded that the hydrocarbons are unstable in contact with molten iron.

In experiment, worked out the parameters of deposition and the composition of the ferromagnetic charge, which ensure a defect-free weld layer (no pores, inclusions, hot and cold cracks) with a surface hardness of 52- 56 HRC without additional technological measures (heating products) and subsequent heat treatment.
