SLM-based additive manufacturing of nickel superalloys still poses significant challenges due to these alloys’ complex composition. With multiple alloying elements and high aluminum/titanium fraction, these materials, when consolidated through SLM form various secondary phases, which affects the processability and leading to weakness within ...
First, the alloy materials are combined in a ball mill and ground to a fine powder. A hot isostatic pressing (HIP) process is then applied to simultaneously compress and sinter the powder. A final heat treatment stage helps remove existing internal stresses produced during any cold compaction [ broken anchor ] which may have been used.
That family is known as the 18Ni maraging steels, from its nickel percentage. There is also a family of cobalt-free maraging steels which are cheaper but not quite as strong; one example is Fe-18.9Ni-4.1Mo-1.9Ti. There has been Russian and Japanese research in Fe-Ni-Mn maraging alloys. [4]
Rising nickel prices are a hot subject among traders today and we’re diving into why interest in the precious metal is increasing. Source: Shutterstock Let’s get right into the nickel prices ...
Inconel alloys are oxidation- and corrosion-resistant. When heated, Inconel forms a thick, stable, passivating oxide layer protecting the surface from further attack. Inconel retains strength over a wide temperature range, attractive for high-temperature applications where aluminum and steel would succumb to creep as a result of thermally ...
Iron powder is commonly used for sintering. Powder metallurgy (PM) is a term covering a wide range of ways in which materials or components are made from metal powders.PM processes are sometimes used to reduce or eliminate the need for subtractive processes in manufacturing, lowering material losses and reducing the cost of the final product.

Nickel aluminide refers to either of two widely used intermetallic compounds, Ni 3 Al or NiAl, but the term is sometimes used to refer to any nickel–aluminium alloy. These alloys are widely used because of their high strength even at high temperature, low density, corrosion resistance, and ease of production. [ 1 ]
In 2004, the company acquired Branford Wire & Manufacturing of Mountain Home, North Carolina. [3] [4] In March 2007, Haynes became a public company via an initial public offering. [5] [6] The Space Shuttle program, which ended in 2011, used total of 47 parts made from Haynes 188 alloy and 7 from Haynes' Hastelloy B alloy in its engines ...
