The experimental results showed that the maximum formable dome height without cracks in warm forming is lower than that in cold forming despite the lower material strength at elevated temperatures. In order to clarify the factors leading to poor stretch formability when using warm forming, the surface temperature and strain in the spherical Cited by: 9.

Erichsen tests using a hemispherical punch with a diameter of 20 mm were carried out atand K to investigate stretch formability of rolled Mg alloy sheets with a diameter of 60 mm, and the Erichsen value, which is the punch stroke at fracture initiation, was measured.

Punch speed was set to 5 mm/min and the blank-holder force was set to 10 by: The mechanical behaviour of the commercial aluminium alloys EN AW, EN AW and EN AW is investigated at temperatures ranging from to 77 K and strain rates from × 10−3 to 6.

Encyclopedia of Iron, Steel, and Their Alloys DOI: the material at elevated temperatures and then baked it at. subsequent re-age-hardening in a low-carbon aluminium-killed steel. Trans. Austenitic stainless steels are classified in the and series, with 16% to 30% chromium and 2% to 20% nickel for enhanced surface quality, formability, increased corrosion and wear resistance.

Austenitic stainless steels are non-hardenable by heat treating. These steels are the most popular grades of stainless produced due to their. Fatigue crack growthstrength. However, at elevated temperatures there are other fatigue that are more common as life limiting factors.

aproduct which requires good stretch formability. The duplex grades have similar formability to in deepdrawing but lower in stretch forming operations. Precipitation hardening.

The generally high aluminum content of this group of alloys assures excellent strength characteristics and oxidation resistance at elevated temperatures (in the range of ˚C ( - ˚F)). Alpha alloys cannot be heat-treated to develop higher strength since they are singlephase : Patrick Dominguez.

This improvement at the elevated temperatures is principal for the aluminum alloys such as and alloys due to the increased strain rate hardening (Shehata et al., ).

Schmoeckel () and Schmoeckel et al. () investigated the drawability of 5XXX series alloys at the elevated : Tailor welded blanks for advanced manufacturing the geometry of the weld seam may also have changed due to the welding process.

Similar optical techniques can be used for determination of the geometry of the weld seam, particularly in the areas close to the thickness step, where the geometry of the weld can play an important role in the.
