Description for inconel metal :
Inconel alloys are typically used in high temperature applications.
Common trade names for Inconel Alloy 625 include: Inconel 625,
Chronin 625, Altemp 625, Haynes 625, Nickelvac 625 and Nicrofer
6020
Properties
Inconel alloys are oxidation- and corrosion-resistant materials
well suited for service in extreme environments subjected to high
pressure and kinetic energy. When heated, Inconel forms a thick and
stable passivating oxide layer protecting the surface from further
attack. Inconel retains strength over a wide temperature range,
attractive for high-temperature applications where aluminium and
steel would succumb to creep as a result of thermally induced
crystal vacancies (see Arrhenius equation). Inconel's high
temperature strength is developed by solid solution strengthening
or precipitation strengthening, depending on the alloy. In
age-hardening or precipitation-strengthening varieties, small
amounts of niobium combine with nickel to form the intermetallic
compound Ni3Nb or gamma double prime (γ''). Gamma prime forms small
cubic crystals that inhibit slip and creep effectively at elevated
temperatures.[12] The formation of gamma-prime crystals increases
over time, especially after three hours of a heat exposure of 850
°C, and continues to grow after 72 hours of exposure.
Description for superalloy:
superalloy is an alloy that exhibits several key characteristics:
excellent mechanical strength, resistance to thermal creep
deformation, good surface stability, and resistance to corrosion or
oxidation. The crystal structure is typically face-centered cubic
austenitic. Examples of such alloys are Hastelloy, Inconel,
Waspaloy, Rene alloys, Incoloy, MP98T, TMS alloys, and CMSX single
crystal alloys.
Description for zirconium alloy
Zirconium alloys are solid solutions of zirconium or other metals,
a common subgroup having the trade mark Zircaloy. Zirconium has
very low absorption cross-section of thermal neutrons, high
hardness, ductility and corrosion resistance. One of the main uses
of zirconium alloys is in nuclear technology, as cladding of fuel
rods in nuclear reactors, especially water reactors. A typical
composition of nuclear-grade zirconium alloys is more than 95
weight percent[1] zirconium and less than 2% of tin, niobium, iron,
chromium, nickel and other metals, which are added to improve
mechanical properties and corrosion resistance
Description for nickel based alloy
These nickel chromium base alloys are used extensively in
applications where heat resistance and/or corrosion resistance is
required. In some members of the group, where conditions are less
demanding, some nickel is replaced by iron to decrease the overall
cost.
Metals fail at high temperatures by both oxidation (scaling) and
through a loss in strength. Alloys in this class are designed to
resist failure from both of these mechanisms. Nickel alloys are not
suitable for high temperature sulphur rich environments.
Where corrosion resistance is significant, molybdenum is used as an
alloying addition in nickel chromium based alloys.
This group of alloys are frequently sold under trade name
specifications but most are listed in the Unified Numbering System.
Common trade names are HASTELLOY, INCOLOY, INCONEL, NICROFER,
NICROM and NIMONIC.
The more recentnickel chromium base alloys in these groups also
have a wide range of ancillary elements added to give special
properties - some of these can be quite complicated and require
very close control over composition and heat treatment.
