Rockwell hardness testing is a method of determining the relative hardness of a material. In this test, hardness is measured by determining the depth of residual penetration by a steel ball or a diamond point under load.
Ferro boron is a type of ferroalloy that is made up of boron and iron. The content of boron varies between17.5% to 20%. Its CAS number is 11108–67-1. It is silver metallic grey solid. Ferro boron can improve the quenching degree and mechanical behavior of steel.
Ferro molybdenum is an alloy formed by combining iron and molybdenum. It is an extremely versatile alloy used primarily in high-strength low alloys and stainless steels. It has numerous properties and can be used even in cast irons, some high-speed tool steels, nickel-based and superalloy
Ferro nickel is a ferroalloy that contains approximately 35% nickel and 65% iron. Its CAS number is 11110-39-7. It is a shiny metallic solid material. It can be obtained from the carbothermic reduction of serpentinic minerals, such as serpentine, limonite, or garnierite.
Ferrosilicon is a ferroalloy, meaning an alloy of iron and silicon. Its CAS number is 8049-17-0. The average silicon content varies between 15 and 90 wt%. It contains a high proportion of iron silicides.
Titanium alloys are metals containing a combination of titanium and other chemical elements such as vanadium, zirconium, palladium, and chromium. They are lightweight and corrosion resistant. Grade 20 Ti-3Al-8V-6Cr-4Zr-4Mo-0.05Pd alloy is a beta wrought alloy.
Titanium is a while metal that is 40% lighter than steel and 60% heavier than aluminum. Titanium alloys are metals containing a combination of titanium and other chemical elements. They are lightweight and corrosion resistant.
Aluminum is a silverish white metal that can be combined with some of these elements – silicon, magnesium, zinc, manganese, and copper to form aluminum alloys.
3D printing and additive manufacturing has the potential to be used within space travel.
