Metals are crystalline in nature and in their solid form, the atoms of alloys or metals exhibit different crystallographic structures, usually cubic structures. Some crystal structures are linked with enhanced properties as compare to others. Moreover, crystalline group of atoms maintain orientation relationships. Consistent crystalline clusters are known as grains, and in an alloy, there … Continue reading Strengthening of Superalloys

Generally the FeCrAl heating Alloys have similar basic chemical composition of 20-25% chromium, 4.5 to 6% aluminum and remaining iron. Other elements are Yttrium and silicon. Properties of FeCrAl The FeCrAl alloys can be processed at temperatures up to 1250oC offering resistance temperature about 1300oC. They possess ferrite structure. Subsequent to fine processing of alloy at … Continue reading FeCrAl heating Alloy- Behavior in different atmospheres

In the Nichrome matrix chromium can be completely dissolved in nickel. The dissolution is highest at 47% in the eutectic temperature and reduces at concentration of 30% at room temperature. Various nickel-chrome alloys are based on this solution that offers superior resistance to elevated temperature oxidation and diverse corrosive media as well as excellent wear resistance. Oxidation … Continue reading Nickel-Chrome resistance alloys- High temperature Corrosion resistance

Sea Water operations need construction material to avoid corrosion due to hard conditions but it should be economical to buy. The alloys that have 6% molybdenum and super austenitic stainless steel are affordable but these couldn’t work in many of the corrosive conditions. Therefore, a Duplex stainless steel 2205 with excellent corrosion resistance as of UNS … Continue reading Duplex stainless steel 2205- Local corrosion resistance

FeCrAl alloy is used as catalytic substrate that is a metallic substrate offering various benefits as compare to ceramic substrates. A metallic substrate offers more resistance to shock and vibration, it offers higher conductance to heat rather than ceramic. Moreover,it can be manufactured easily in thin foil and offers honeycomb structure to render broad surface area … Continue reading FeCrAl Resistance Heating Alloy-Scaling Resistance

A fixed position electric heater produces heat through the passage of current to the heating element that is made of a Nichrome resistance heating wire Ni80Cr20. The Nichrome heating element can be covered in a metal sheath shielded with a magnesium oxide powder or can be kept in open coil geometry.Generally, the heating element is … Continue reading Nichrome in Fixed position electric heaters
