Die Material Selection Criteria for Aluminum Hot Stamping

Journal of Manufacturing and Materials Processing, 2021
The aim of this work is to develop a die material selection criterion for aluminum hot stamping applications. The criterion has been based on the back-to-back comparison of a set of reciprocating friction and wear tests.

Effect on Blank Holding Force on Blank Deformation at Direct and Indirect Hot Deep Drawings of Boron Steel Sheets

Metals, 2018
This study involves performing direct and indirect hot press forming on ultra-high-strength steel (UHSS) boron steel sheets to determine formability. The indirect hot press process is performed as a cold deep drawing process, while the direct hot press ...

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.

Adjust operating conditions of an in-made house horizontal hydraulic press for a 90° cold bending process

Revista de Ciencias Tecnológicas, 2023
During the cold-bending process, the tooling suffers considerable damage due to excess pressure. This also causes the machines to break down, causing problems in the precision and quality of the metal parts formed. The precision depends on the operating

Comparison of Ceramic Waste forms Produced by hot Uniaxial Pressing and by Cold Pressing and Sintering [PDF]

MRS Proceedings, 1994
AbstractSynroc C waste form specimens prepared using the Australian-developed technology are uniaxially pressed in stainless steel bellows at 1200°C and 20MPa. This produces a material with high chemical and physical durability and with the radioactivity enclosed inside both the waste form and the bellows. An alternative method of producing the ceramic

Repurposing steel press production lines for hot formed high-strength aluminium automotive body components

Advances in Industrial and Manufacturing Engineering, 2022
Climate change and normative requirements are forcing car manufacturers to make their products ever lighter despite the highest safety requirements. For this case study a high-strength EN AW-7075 alloy is used as an example of how hot formed aluminium ...

A Study on the Cooling Performance of Newly Developed Slice Die in the Hot Press Forming Process

Metals, 2018
The cooling performance of a slice die is studied numerically and experimentally. The slice die is designed to improve the cooling performance compared to that of a conventional die that is generally used in the Hot Press Forming (HPF) process by ...

Thermomechanical Treatment of Martensitic Stainless Steels Sheets and Its Effects on Their Deep Drawability and Resulting Hardness in Press Hardening

Metals, 2020
The deep drawability of three Martensitic Stainless Steels (MSS) alloys under conventional press hardening thermomechanical process conditions was investigated. The three alloys differ in the content of the main elements C and Cr.
