“A team of engineers from North Carolina State University looked to eutectic gallium indium (EGaIn) – a metal with a melting point of ∼15.5 °C – to produce thin wires at room temperature. Conventional electrical wires are fabricated by using large forces to repeatedly pull and elongate a metal rod that had been produced at high temperatures. The approach taken by Prof. Michael Dickey and his team is rather different.”

“This resistance to oxidation is possible because of the presence of aluminum in layers between molybdenum and boron layers,” Barsoum said. “When heated to high temperatures in air the aluminum atoms selectively diffuse to the surface and react with oxygen – forming a surface aluminum oxide, or alumina, protective layer that slows down further oxidation considerably. So the material forms its own protective coating.”

Molten Iron is produced directly using iron ore fines and non-coking coal rather than processing through a sinter plant and coke ovens as traditional blast furnace route. In the Finex process, iron ore fines are charged into a series of fluidized-bed reactors. The fines pass in a downward direction where they are heated and reduced to direct-reduced iron (DRI) by means of a reduction gas – derived from the gasification of the coal – that flows in the counter – current direction to the ore. The DRI fines are then hot-compacted to hot-compacted iron, transferred to a charging bin positioned above a melter gasifier where smelting take place. The tapped product, liquid hot metal, is equivalent in quality to the hot metal produced in a blast furnace ore Corex plant.

Like most other heat treatments, the carburizing and hardening process is known to introduce dimensional changes and gear distortion [4]. If these size and shape changes can be anticipated and controlled, it is possible to eliminate post–heat treatment machining by designing ring gears that would allow for the heat treat change. Such gear manufacturing would significantly reduce cost and machining-to-assembly time, both of which are critical in a commercial environment and large-scale production.

Record Gas Quenching Speeds Achieved in Ipsen’s ARGOS Heat Treating System

KLEVE, GERMANY – Ipsen’s Global Development Team recently celebrated the first build and testing of the ARGOS heat-treating system. The ARGOS uses low-pressure carburizing (AvaC®) in combination with 20-bar nitrogen quenching to provide metallurgical properties never before seen in gas quenching systems – even those utilizing 20-bar helium quenching. One industry visitor who witnessed the test run commented, “The ARGOS is likely the fastest inert gas quench furnace in the world.”

This initial test was performed on one of the most difficult to quench vacuum carburized components: layshafts for large gears. Until now, helium gas, which is both expensive and declining in availability, was required to fully transform parts with very high cross-sectional thicknesses.

Test outcomes showed that the shafts processed in the ARGOS system with 20-bar nitrogen quenching achieved higher surface hardness and core hardness values than shafts processed in the existing vacuum heat-treating furnaces that use 20-bar helium quenching. The ARGOS heat-treating system also offers several benefits, including:

  • Flexible installation with a selectable number of carburizing, nitriding, subzero and high vacuum process chambers with a nitrogen gas and/or oil quench module
  • Excellent temperature uniformity during heating and cooling
  • Minimal and controllable distortion due to temperature homogeneity throughout the entire load and the reversible gas flow during cooling
  • Extremely high gas velocity and volume due to Ipsen’s unique cooling system design

Overall, the ARGOS furnace line represents a significant milestone in the growing trend to operate low-pressure carburizing (LPC) lines in combination with inert gas quenching.
