Thermoplastic-based fibre metal laminates (FMLs) have gained increasing interest in the automotive industry due to their forming potential—especially at higher temperatures—into complex components compared thermoset-based ones. However, several challenges arise while processing thermoplastic-based FMLs. One one hand, room temperature (RT) leads early failure modes, e.g., fracture and delaminati...

ausser der traditionellen nutzung der geothermalen energie sind in jungster zeit neue erkenntnisse und projekte in ausarbeitung, die fur die zukunft ausserst wichtig sein konnen. bei einigen dieser projekte hat man bereits einige sehr positive ergebnisse erzielt. ausserdem wurde klar, das die ausgaben fur exploration,und expleitaion wirtscnaftlich ohneweiteres vsrtretbar sind,j•a sogar in hinbl...

Abstract Heat transfer and stress distribution are studied using computational fluid dynamic structural simulation for a conformal cooling die insert made of Maraging M300 steel by selective laser melting. The phase transformation water is to understand the effects concentration on life. results validated in production. failure has been revealed result enhanced corrosion directly related format...

Abstract Slug pulling, adhesion formation and edge fracture are major challenges in the sheet metal processing industry. They lead to a strong reduction part quality, process stability as well profitability. In this study, investigations carried out on stainless steel X5CrNi18-10 address previous mentioned challenges. While slug pulling strongly depend geometric characteristics of active elemen...

This paper studies the influence of substrate bias on structure and performance multi-arc ion plating TiCrAlN film surface H13 die steel. Using technology, by controlling adjusting size bias, different structures properties are prepared steel substrate. The research results show that when voltage gradually increases, number large particles decreases, particle distribution becomes more uniform, ...

Since the die-casting mold repeats rapid heating and cooling during operation, defects such as heat checks generate. Therefore, quality life of are degraded. To improve these demerits, improvement thermal conductivity material is effective. In this study, carbon fibers were added to SKD61(40CrMoV5) tool steel fabricate composites with high conductivity. fiber has a chemical reaction steel, elec...

Herein, the microstructure stability of a newly developed hot‐working die (HWD700) steel at elevated temperatures up to 700 °C is investigated using transmission electron microscopy (TEM), selected‐area diffraction, energy‐dispersive spectrometer, and high‐resolution microscope. The results show that HWD700 exhibits higher thermal than commercial H13 when temperature °C. After quenching temperi...

Rectangular waveguide is one of the earliest types of transmission lines. Rectangular waveguide can be produced by hot extrusion process. In this paper, the hot extrusion process of CuZn5 rectangular waveguide was investigated by Finite Element Method (FEM). In addition, Genetic Algorithm (GA) was used to optimize the die geometry and process conditions to achieve the lowest magnitude of extrus...
