Brass, or any of the copper alloys, can be made to coat the iron, in the same manner as the copper. We hope this new process will be the means of extending the use ot sheet-iron, soi as to save ...

Fragments of copper alloy unearthed at one of Britain's most important archaeology sites have been revealed to be parts of an incredibly rare Iron Age helmet. The discovery was made by the British ...

This precaution is not necessary, unless the alloy contains a metal requiring a high temperature for its fusion, as, for instance, copper or iron. In alloys oontaining tin, however, a laler of ...

This method uses ribbons of an iron-copper-boron alloy and exposes it to an atmosphere of ammonia and hydrogen at 550°C for 28 hours, followed by a rapid treatment at 700°C and an ice-water quench.

Since iron, nickel, copper, and cobalt can all be processed this way, high-entropy alloys could be the next focus. These ...

IT is generally accepted that the lattice parameter of retained austenite in quenched iron—carbon alloys increases continuously and linearly with the increase of carbon content. So far ...
