Herein, a new kind of overaging strategy: two steps for tailor rolled blank dual phase steel (DP-TRB) was investigated. The results indicate that the process is useful way to control mechanical properties DP-TRB. In premise satisfying requirement strength DP590 grade, total elongation can be significantly increased (3~7% in most cases). Due different degrees ferrite recrystallization (differenc...

A new algorithm based on the sweep plane approach to determine the machined part geometry in 5-axis machining with general APT tools is presented. Undercut and overcut can be determined. Collision detection between the toolholder, workpiece and workpiece fixture can also be detected. The subtraction of the removed material is obtained for each sweep plane by using a stencil buffer. A flat plane...

Unlike existing uniform thickness structures, tailor rolled blank (TRB) which allows continuous metal thickness charges has been recently gaining comprehensive attention due to its excellent lightweight potential. The aim of this study is to combine the advantages of the TRB manufacturing technology with the structural optimization methodology to design the front longitudinal beam under impact ...

A finite element model is proposed to investigate the effect of thickness differential on Limiting Dome Height (LDH) testing aluminum tailor-welded blanks. The numerical validated via comparison equivalent plastic strain and displacement distribution between simulation results experimental data. normalized LDH values are as a means quantifying influence for variety different ratios. Increasing ...

Abstract The majority of parts in modern car bodies is manufactured from sheet metal. Rarely these are fully stressed due to design space restrictions and complex requirements. usage tailor rolled blanks (TRB) enables the reduction thickness areas less loaded thus reduces part weight. Technically most metal potentially suited for application TRB. Economic circumstances like additional flexible ...

The purpose of this study was to develop a specialized Friction Stir Welding process for superplastic grade aluminum alloy 5083-SP and titanium alloy 6Al-4V, in thickness of 1.5 to 4 mm, such that the butt welded nugget would have equal superplastic forming (SPF) characteristics as the parent sheet material The concept of using tailored blanks for the SPF process is proposed which will allow th...

objectives: this study aimed to evaluate the effect of different ceramic surface treatments after machining grinding on the biaxial flexural strength (bfs) of machinable dental ceramics with different crystalline phases. materials and methods: disk-shape specimens (10mm in diameter and 1.3mm in thickness) of machinable ceramic cores (two silica-based and one zirconia-based ceramics) were prepar...
