Sheet Metal Formability Analysis Training. ... We've developed forming limit curves for sheet aluminum, zirconium, nickel, brass, and titanium alloys, as well as numerous stainless steel and Advanced High Strength Steel (AHSS) grades. Let us know how we can help solve your challenges!
The HSLA steels in sheet or plate form have low carbon content (0.05 to −0.25% C) in order to produce adequate formability and weldability, and they have manganese content up to 2.0%. Small quantities of chromium, nickel, molybdenum, copper, nitrogen, vanadium, niobium, titanium, and zirconium are used in various combinations. HSLA Steel ...
Steel, Sheet and Strip, Hot-Rolled, Carbon, Structural, High-Strength Low-Alloy, High-Strength Low-Alloy with Improved Formability, and Ultra-High Strength1 This standard is issued under the fixed designation A 1011/A 1011M; the number immediately following the designation indicates the
Due to the poor formability of zirconium alloy, crack is one of its most common failure modes when the alloy is used for strips of spacer grids of nuclear fuel assembly during the sheet forming process. In this paper, the relationships between processing parameters (including punching speed, stamping clearance and blank-holder force (BHF)) and ...
The zirconium alloy used in this study is SZA6 sheet with the thickness of 0.457 mm and its nominal composition (Le et al., 2017) is Zr-0.5Sn-0.5Nb-0.3Fe-0.015Si. The clamping rigidity and convexity characteristic of strips used to fix fuel rods in the nuclear fuel assembly is selected as the stamping product while its geometry structure and ...
Therefore, research on the formability of zirconium alloy sheet is . very necessary. Generally, there are many factors which affected the formability of zirconium alloy . sheet.
The formability of sheet zirconium has not been clarified enough. Besides, the numerical analysis of the forming processes of sheet zirconium has never been carried out. In the present study, the formability of a commercially pure zirconium sheet in fundamental forming processes, i.e. in deep drawing, stretching and bore-expanding processes, is ...
correspondingly large differences in formability are obtainable at room temperature. The tensile ... that contain aluminum, tin, and/or zirconium are preferred for high-temperature and cryogenic applications. Alpha-rich alloys are generally ... use sheet material in the annealed condition to eliminate this problem.
Technical Data Sheet ATI Zircadyne® Zirconium ... to increase its strength and improve its formability. Table 1 shows the chemical composition of Zircadyne alloys. The presence of hafnium in Zircadyne alloys does not significantly influence the physical, mechanical, or corrosion properties. ...

The sheet formability of zirconium is supposed to be much different from that of cubic metals. In order to find the forming method and conditions suitable for sheet zirconium, the deformation behaviour in forming processes has to be investigated in detail.
The work should be flooded or sprayed with a coolant to completely wash away all chips from the tool. The penetration can range from .005 to .010 inch per tooth at 150 to 250 SFPM. The work absorbs about 10 percent of the cutting energy with sharp cutters. Hafnium requires only about 75 percent of the horsepower required for SAE 1020 CR steel.
Zirconium 705 is alloyed with Niobium to increase its strength and improve its formability. Zirconium is a reactive metal that has a high affinity for oxygen resulting in the formation of a protective oxide layer in air at room temperature. This protective oxide gives Zirconium alloys their superior corrosion resistance.
Due to the poor formability of zirconium alloy, crack is one of its most common failure modes when the alloy is used for strips of spacer grids of nuclear fuel assembly during the sheet forming ...
Formability refers to the ability of sheet metal to be formed into a desired shape without necking or cracking. Necking is localized thinning of the metal that is greater than the thinning of the surrounding metal. Necking precedes cracking. From the metallurgical perspective, the formability of a particular metal depends on the metal's ...
