Heat resistant super alloys (HRSA) fall into three material groups; nickel-based, iron-based and cobalt-based alloys. Titanium can be pure or alloyed. The machinability of both HRSA and titanium is poor, especially in an aged condition, requiring particular demands on the cutting tools. HRSA and titanium alloys
Alloying of elemental blends achieved through high-energy ball milling (HEBM) is referred to as mechanical alloying (MA), which is a solid-state powder processing technique involving the repeated deformation, fracture and welding of powder particles [1,2,3,4].This technique was originally developed to produce oxide-dispersion …

For purposes of machining nickel alloys are classified in four groups and two subgroups: •Group A: Consists of alloys containing 95% or more nickel. These alloys have moderate mechanical strength and high toughness. They are hardened only by cold work. The alloys are quite gummy in the annealed and the hot-worked condition, and cold-drawn
During alloy formation using ball-mill, two processes simultaneously occur: (a) fracturing, and (b) cold welding of powders. Thus, it becomes imperative to create a balance between these processes for successful alloying. In mechanical alloying, planetary ball mill is commonly employed because it involves very small quantities of precursor powders.
In the present research work the mixture of boron carbide and graphite ceramic powders with a theoretical composition of 50% each by weight were mechanically alloyed in a laboratory ball mill with ...

The United States had only one active nickel mine in 2013. There are also small amounts of by-product nickel recovered from copper and palladium-platinum ores in the Western United States. More than 80,000 tons of nickel is recovered annually by recycling stainless steel and other nickel-iron alloys.
