Analysis of non-isothermal warm deep drawing of dual-phase DP600 steel

International Journal of Material Forming, 2018
Improving the formability of the material is a key issue in the deep drawing process. Heating the material above its recrystallization temperature drastically increases formability, but in the case of dual phase (DP) steels, it results in a loss of their mechanical properties.

Experimental research on warm deep drawing of HC420LA grade sheet material

The International Journal of Advanced Manufacturing Technology, 2016
The use of high-strength sheet material applications in the automotive industry has become widespread due to their high strength/weight ratios. The formability, however, of these high-strength sheet materials is limited at room temperatures (RTs).

Numerical optimization of warm hydromechanical deep drawing process parameters and its experimental verification

Journal of Manufacturing Processes, 2020
Abstract Warm Hydromechanical Deep Drawing (WHDD) is considered as an effective sheet metal forming process to overcome low formability problems of lightweight materials, such as aluminum and magnesium alloys, at room temperature. WHDD process combines the advantages of Hydromechanical Deep Drawing (HDD) and Warm Deep Drawing (WDD) processes. In this

The circumgalactic medium of massive galaxies at z~3: a test for stellar feedback, galactic outflows, and cold streams [PDF]

, 2013
We present new results on the kinematics, thermal and ionization state, and spatial distribution of metal-enriched gas in the circumgalactic medium (CGM) of massive galaxies at redshift 3, using the "Eris" suite of cosmological "zoom-in" simulations. The

Toward a Circular Economy in Deep Drawing: Remanufacturing End-of-Life Automotive Parts [PDF]

MATEC Web of Conferences
Recycling aluminium typically involves energy-intensive melting processes. This study presents a more sustainable approach by directly remanufacturing deep-drawn parts from end-of-life aluminium automotive components.

Circular and square cups drawing and ironing of Ti alloy sheets by incremental press forming method [PDF]

MATEC Web of Conferences
The low ductility of Ti–6Al–4V alloy at forming temperatures below 780°C is still a problem. Ti–6Al–IV alloy is usually hot press formed at 780 to 900°C.

Comparison of the Mechanical Properties and Forming Behavior of Two Texture-Weakened Mg-Sheet Alloys Produced by Twin Roll Casting

Frontiers in Materials, 2019
The influence of rolling and annealing on the resulting mechanical properties and forming behavior of Mg-Zn-RE and Mg-Zn-Ca alloys produced via twin roll casting is investigated. After hot rolling followed by an annealing treatment, both alloys develop a
