2. Widmanstätten pattern - Wikipedia

   en.wikipedia.org/wiki/Widmanstätten_pattern

   Widmanstätten patterns, also known as Thomson structures, are figures of long phases of nickel–iron, found in the octahedrite shapes of iron meteorite crystals and some pallasites. Iron meteorites are very often formed from a single crystal of iron-nickel alloy, or sometimes a number of large crystals that may be many meters in size, and ...

3. Precipitation hardening - Wikipedia

   en.wikipedia.org/wiki/Precipitation_hardening

   Precipitation hardening, also called age hardening or particle hardening, is a heat treatment technique used to increase the yield strength of malleable materials, including most structural alloys of aluminium, magnesium, nickel, titanium, and some steels, stainless steels, and duplex stainless steel.

4. Work hardening - Wikipedia

   en.wikipedia.org/wiki/Work_hardening

   The work-hardened steel bar fractures when the applied stress exceeds the usual fracture stress and the strain exceeds usual fracture strain. This may be considered to be the elastic limit and the yield stress is now equal to the fracture toughness, which is much higher than a non-work-hardened steel yield stress.

5. Stainless steel - Wikipedia

   en.wikipedia.org/wiki/Stainless_steel

   Stainless steel, also known as inox, corrosion-resistant steel (CRES), and rustless steel, is an iron-based alloy containing a minimum level of chromium that is resistant to rusting and corrosion. Stainless steel's resistance to corrosion results from the 10.5%, or more, chromium content which forms a passive film that can protect the material ...

6. Flask (metal casting) - Wikipedia

   en.wikipedia.org/wiki/Flask_(metal_casting)

   Round flasks. A flask is a type of tooling used to contain a mold in metal casting.A flask has only sides, and no top or bottom, and forms a frame around the mold, which is typically made of molding sand.

7. Duplex stainless steel - Wikipedia

   en.wikipedia.org/wiki/Duplex_Stainless_Steel

   Duplex steels also have higher strength. For example, a Type 304 stainless steel has a 0.2% proof strength in the region of 280 MPa (41 ksi), a 22%Cr duplex stainless steel a minimum 0.2% proof strength of some 450 MPa (65 ksi) and a superduplex grade a minimum of 550 MPa (80 ksi). [6]

9. Leeb rebound hardness test - Wikipedia

   en.wikipedia.org/wiki/Leeb_rebound_hardness_test

   A test takes a mere 2 seconds and, using the standard probe D, leaves an indentation of just ~0.5 mm in diameter on steel or steel casting with a Leeb hardness of 600 HLD. By comparison, a Brinell indentation on the same material is ~3 mm (hardness value ~400 HBW 10/3000), with a standard-compliant measuring time of ~15 seconds plus the time ...
