·Applying high strength materials beside high strength steels like DP1000,TRIP780 recently aluminium alloys,e.g.AA7021 or AA7075 have a positive response for many of the requirements increasing strength results in the application of thinner sheets together with significant mass reduction,leading to lower consumption with increased environment protection; however it canApplication of Hot Forming High Strength Steel Parts on Application of Hot Forming High Strength Steel Parts on Car Body in Side Impact SUN Hongtu 1,2 ,HU Ping 1,2,* ,MA Ning 1,2 ,SHEN Guozhe 1,2 ,LIU Bo 3 ,and ZHOU Dinglu 3Author Fu Li Lu,Ji Shun Song,Jian Zhang,Xiu Ping YanPublish Year 2013Ausforming Process and Applications Steel MetallurgyAusforming (after hardening and tempering) results in higher yield and the tensile strength as compared to conventionally tempered martensite steel without adverse effect on ductility and toughness.Ausforming requires careful control to be successful and also
Apr 10,2020·The steel then becomes pearlite,bainite,or if kept hot long enough,ferrite.None of the microstructures just stated have the same strength as martensite after tempering and are generally seen as unfavorable for most applications.The successful heat treatment of a steel depends on three factors The size and shape of the specimenCited by 2Publish Year 1979Author John J.Jurkowski,M.GonzalesAdvanced High-Strength Steels Add Strength and Ductility Laser welding two sheets of dissimilar-thickness or dissimilar-grade steel together puts strength where it is needed in a single steel stamping.Hydroforming a continuous hollow tube to the desiredCited by 57Publish Year 2018Author Jean-Hubert Schmitt,Thierry IungHigher-strength steels - Schuler GroupHigher strength steels have been in use since the 1990s,primarily for structural components.There is a distinction made between Micro-alloyed steels.Micro-alloyed steels have been in use for a considerable time.They combine relatively good formability with high tensile strength.Designation ZStE 260,ZStE 300,ZStE 340,ZStE 380,ZStE 420.

The choice of a specific high-strength steel depends on a number of application requirements including thickness reduction,corrosion resist-ance,formability,and weldability.For many applications,the most impor-tant factor in the steel selection process is the favorable strength-to-weight Art-3b.qxd 10/23/01 4:39 AM Page 194New developments of advanced high-strength steels for ·Automotive industry asks for higher resistant steels to lighten parts and improve crash resistance.Keeping a good ductility while increasing tensile strength requires the development of new grades in which hardening mechanisms counteract the drop inProperties and automotive applications of advanced high Jan 01,2015·Substituting a steel grade with a higher strength or advanced high-strength steel (AHSS) does not improve component stiffness; however,the added formability of AHSS allows additional geometric form to be added to improve component stiffness.The additional component stiffness allows for reductions in the sheet thickness to reduce mass.
