Super alloys or high performance alloys are available in a variety of shapes and contain elements in different combinations to obtain a specific result. These alloys are of three types that include iron-based, cobalt-based and nickel-based alloys.
Super alloy or high performance alloys have good creep and oxidation resistance, and are available in different forms. Cobalt-based, nickel-based, and iron-based alloys are three groups of super alloys.
Super alloys or high performance alloys have the ability to function at high temperatures and under mechanical stress. They have good creep and oxidation resistance, and are available in different forms.
Master alloys are semi-finished products available in a variety of shapes. These alloys are referred to as grain refiners, modifiers or hardeners based on their usage. In comparison with pure metals, master alloys are more economical.
In order to analyze mirocystins (MCs) in drinking water, an LC-MS/MS technique has been devised by direct injection on EVOQ Elite model triple quadrupole mass spectrometer.
Zirconium is a strong, ductile and malleable metal whose physical and chemical properties are similar to that of titanium. It has good corrosion and heat resistance. At elevated temperatures, the finely divided metal is capable of igniting spontaneously in air.
Tungsten has high electrical and thermal conductivity, and low vapor pressure at high temperature. It has high meting point compared to all other metallic materials.

Rhenium has high melting point of 3180°C next to tungsten. The ductility of rhenium can be maintained even after recrystallization. It is best-suited for filaments due to its high electrical resistivity and low vapor pressure.
