Warm Forming of Mg Sheets: From Incremental to Electromagnetic Forming
Metallurgical and Materials Transactions A, 2014Magnesium alloys are generating interest in the automotive and aeronautic industries due to their low density and potential to reduce gross vehicular weight. However, the formability of these alloys is poor and they are very difficult to be formed at room temperature due to their strong basal texture in rolled form.

An Empirical Analysis of Urban Form, Transport, and Global Warming
The Energy Journal, 2008Does urban form affect travel choices and thus C02 emissions by individuals? If this is the case, then urban form and policies that influence it deserve serious attention in the context of long-term climate policy. To address this issue, we examine the impact of urban density on commuting behavior, and the consequences for C02 emissions.

Advantages of Servo Presses in Metal Forming With a Focus on Warm Forming of Sheets
ASME 2010 International Manufacturing Science and Engineering Conference, Volume 1, 2010Servo presses are recently introduced metal forming machinery and they are in many ways, a hybrid of mechanical and hydraulic presses. They are designed to combine the strengths of conventional mechanical and hydraulic presses, and at the same time to minimize their constraints.

DLC for tools protection in warm massive forming
Diamond and Related Materials, 2003Abstract In order to find an alternative to solid lubricants in bulk metal forming with contact temperatures between work piece and tool up to 600 °C, low wear friction coatings like hydrogenated amorphous diamond-like carbon (DLC), silicon doped diamond-like carbon (Si-DLC), sputtered molybdenum disulfide and a multilayer system of TiC and TiN (TiCN)

Warm incremental forming of magnesium alloy AZ31
CIRP Annals, 2008Industrial application of magnesium alloy AZ31 is dramatically increasing due to the very competitive mechanical strength vs. weight ratio. On the other hand, AZ31 is very difficult to be formed at room temperature. In this study incremental forming of the above material is taken into account, with particular reference to formability limits.

Alloyability of warm formed FeCrAl powder compacts
Materials Today Communications, 2015Abstract Alloyability of warm formed Fe-based powder compacts is presented here. Iron (Fe) powder ASC100.29 was mixed with other alloying elements, namely chromium (Cr), and aluminum (Al) powder for 60 min and compacted at 150 °C by applying 130 kN axial loading, simultaneously from upper and lower punches to generate green compacts.

Determination of warm forming limit diagram for ZEK100
AIP Conference Proceedings, 2013The formability of a rare-earth alloyed magnesium sheet, ZEK100, is studied through determination of its Forming Limit Diagram (FLD). Limiting dome height experiments were performed at elevated temperatures with in situ digital image correlation (DIC) measurement of strain.

Warm forming of aluminium/magnesium alloy sheet
Journal of Mechanical Working Technology, 1978At this time, when energy conservation is gaining popularity, the increased use of aluminium sheets for motor-car body construction to reduce the overall weight of the car, and so use less fuel, is appropriate. Pure aluminium, as used in the days of hand-made bodies, is now quite out of the question for the mass-produced car, due to inherent softness ...

Development of a Processing Map for Use in Warm-Forming and Hot-Forming Processes
Metallurgical Transactions A, 1981A fracture initiation map is developed which should be useful in fast forming operations at strain rates greater than about 10-3 s-1 at elevated temperatures. Two types of cavitation mechanisms, one pertaining to cavity formation at second phase particles, as in ductile fracture, and the other pertaining to wedge type microcracking at grain boundaries,
